Basic building design concepts – sounds like dry compulsory reading from the first semester, but it is the secret toolbox without which no architectural design, no building application and certainly no sustainable building can function. If you don’t know these basics, you’ll just plan pretty renderings – and leave the building to others.

  • What is behind the most important basic building design concepts – and why are they more relevant today than ever?
  • How do the approaches in Germany, Austria and Switzerland differ – and where is the potential for innovation?
  • What role do digitalization and AI play in structural engineering practice?
  • What challenges and solutions are there when it comes to sustainability and resource efficiency?
  • What technical expertise is expected of architects and engineers today?
  • How are new materials, construction methods and standards changing the profession?
  • Where are the biggest misunderstandings or stumbling blocks in dealing with design principles?
  • What do international experts think – and why is the topic being hotly debated worldwide?

Basic construction terms – the underestimated foundation of architecture

Any architect or engineer who believes that basic building design concepts are a relic from the days when people still drew with ink on tracing paper is very much mistaken. In fact, these concepts form the backbone of all serious planning – not only in the traditional age, but especially in the digital age. From the floor slab to the roof construction, from the wall structure to the façade, from statics to moisture protection: without a solid understanding of the basic building construction, every building remains a paper tiger. In Germany, Austria and Switzerland, these concepts are firmly anchored in training and construction practice – and yet they are often criminally underestimated in everyday life. This comes back to haunt them at the latest when the beautiful design idea fails due to its feasibility or the building produces refurbishment cases after a few years.

The basic concepts of building design are essentially universal – but their use varies depending on the country, region and building culture. While Germany is dominated by a flood of standards and every detail seems to be regulated, Austria and Switzerland often rely on pragmatic solutions and traditional craftsmanship. However, the challenges are similar everywhere: increasing demands on sustainability, energy efficiency and resource conservation, growing complexity due to new materials and construction methods and, last but not least, the pressure to integrate digital methods into analog building construction. Anyone who is not up to speed here quickly loses touch – or gets stuck in the thicket of paragraphs and construction management details.

The fatal thing is that many young architects believe they can revolutionize the construction world with BIM, 3D modelling and a few clever plug-ins. But without an understanding of how a wall structure really works, how loads are transferred or how a waterproofing layer needs to be dimensioned, any digital twin remains a beautiful illusion. The result: planning errors, structural damage and endless supplements – and the realization that the basics of building construction cannot be outsourced or automated.

The basic concepts of building design are more than just vocabulary for inspections or checklists for building applications. They are the DNA of construction, the common vocabulary of architects, engineers, tradespeople and clients. Without them, all communication on the construction site would be a Babylonian confusion of languages – and no building would survive its first decade. Those who master it can have a say, participate in planning and decision-making – and make themselves indispensable in the planning process.

And yet: the understanding of structural design principles is not static. It changes with every new material, every new standard, every digital tool. If you want to build successfully today, you have to be prepared to constantly question your basic concepts, add to them and adapt them to reality. This is uncomfortable, but there is no alternative – at least for anyone who wants more than just pretty renderings for competitions.

Germany, Austria, Switzerland – three building cultures, one construction canon?

A look across the borders shows: At first glance, the basic building construction terms may seem the same everywhere – wall, ceiling, foundation, roof, joint, insulation, sealing, supporting structure – but their use and application sometimes differ considerably. In Germany, the principle of standardization rules. The DIN series, the model building regulations, the EnEV and its successors dictate down to the last detail how buildings may and should be built. This leads to impressive technical precision – but also to a certain tendency towards over-regulation. There is a regulation, a guideline, a certificate for everything. This has advantages in terms of planning security, but also creates frustration and barriers to innovation. If you want to try something new, you often have to overcome the bureaucracy of standards first.

In Austria, there is greater serenity in dealing with building design rules. The ÖNORM standards are less all-encompassing, and many things are solved pragmatically on the basis of experience, craftsmanship and regional building culture. The result is a greater variety of solutions – but also greater responsibility on the part of planners to make the right decisions. Switzerland, on the other hand, stands out for its precision and the close link between planning and execution. Here, building construction is often understood as a strategic discipline in which innovation and quality are not opposites, but rather both a goal and an aspiration. Swiss building culture is characterized by a constant striving for improvement – and this is also evident in the way construction principles are handled.

But despite all the differences, the three countries face the same challenges. The requirements for thermal insulation, sound insulation, fire protection and sustainability are constantly increasing. New materials such as wood-concrete composite systems, recycled building materials or aerogel-based insulation call for new construction details and new ways of thinking. And digitalization does not stop at the basic concepts of building construction – on the contrary: it brings new opportunities, but also new risks. The question of how much standardization makes sense, how much innovation should be allowed and how to separate the wheat from the chaff remains topical everywhere.

The exchange between countries is more intensive than ever. International standards, cross-border projects and the global construction industry ensure that the basic concepts of building construction are constantly evolving. But the core remains the same: Those who have not mastered the basics will not be able to survive in an international context. The building culture of the future will be hybrid, digital and sustainable – but it needs a solid foundation of building construction knowledge. Anyone who thinks they can skimp on this knowledge will quickly be caught up in reality – and overtaken by colleagues from abroad.

The art lies in using the strengths of the respective building culture without getting lost in bureaucracy, regionalism or the romance of innovation. The best solutions are created where standards and experimentation, experience and digital tools, craftsmanship and high-tech interact. This applies to Germany, Austria and Switzerland – and to the global architectural discourse anyway.

Digitalization, AI and the renaissance of building construction

Digitalization has not abolished building construction – it has transformed it. Anyone talking about basic building design terms today can no longer avoid BIM, parametric planning, simulation and AI. It sounds like buzzword bingo, but it has long been part of everyday life on many construction sites and in more and more planning offices. The question is no longer whether digital models will influence building construction, but how profoundly they will change everyday planning and which skills are really required.

With BIM and digital twins, wall superstructures, load-bearing structures and façade details can no longer just be drawn, but simulated, analyzed and changed in real time. This opens up new possibilities – but also new chasms. Anyone who does not understand the design principles will only produce errors in 3D with digital tools. The danger of automation is that apparent intelligence replaces the experience and knowledge of the planners. The result: incorrect details, inconsistent models and flying blind during construction.

Artificial intelligence promises to revolutionize construction planning. Algorithms can calculate load transfers, suggest optimal material combinations or evaluate the sustainability of components. However, AI is no substitute for structural design education – it is only as good as the data it is fed with. Anyone who thinks they can solve all construction problems with just a few clicks is very much mistaken. The future lies in the combination of human expertise and digital support – not in blindly relying on smart tools.

Digitalization has also created new challenges. The question of data sovereignty, interface standards and the traceability of decisions is becoming increasingly urgent. Who controls the digital building data? How are changes documented? And how can structural design errors be prevented from only becoming apparent on the construction site because the model was too abstract or too complex? These questions will occupy the industry in the coming years – and they show that the basic concepts of building design are not dying out, but are experiencing a renaissance.

The winners are those who have mastered the basics and are prepared to use new tools at the same time. Planners who speak the language of structural design and can translate it into digital models are urgently needed on the job market. Digitalization is not a sure-fire success – it is a catalyst for competence, for a culture of error and for the continuous further development of structural design practice. Those who recognize this will not be replaced by technology, but will use it to enhance their own skills.

Sustainability, resource efficiency and the new demands on building design

The days when building construction consisted only of statics and waterproofing are over. Sustainability, resource efficiency and the circular economy are the new buzzwords – and they are putting the basic concepts of building design to the test. Today, a roof is no longer just weather protection, but an energy generator, living space and material store all in one. A wall is no longer just a partition, but a climate buffer, storage and design element. If you don’t rethink this, you will miss out on the future – and risk your building being considered an old building tomorrow.

The requirements for sustainable building constructions are high. Materials must be reusable, separable and free of harmful substances, and constructions must be designed to be dismantlable and adaptable. This sounds like idealism, but it has long been a reality on the international market. Switzerland and Austria are pioneers in resource-saving constructions, while in Germany the primacy of economic efficiency still reigns too often. But the truth is: those who do not take sustainable building designs seriously are quickly punished by investors, clients and legislators.

The integration of sustainability into building design practice requires new knowledge – and a new understanding of the basic concepts. What does a “load-bearing wall” actually mean today when modular systems and flexible floor plans are in demand? How do you define an “insulation standard” when gray energy and life cycle costs are more important than pure U-values? And what does a “watertight” construction look like when extreme weather and heavy rainfall are becoming the new normal? The answers to these questions are complex – and they require constant further development of the building design principles.

Innovative solutions are created where specialist knowledge, creativity and digital methods interact. This could be the use of recycled materials, the development of new joining techniques, the integration of sensor technology to monitor components or the use of digital twins to optimize material flows. The challenges are great – but so are the opportunities. Anyone who understands the basic concepts of building design as a dynamic tool can create sustainable, robust and future-proof buildings.

Building design is becoming the scene of social debates. How much comfort is necessary, how much technology makes sense, how much material is enough? The answers to these questions are being demanded not only by experts, but by society as a whole. The basic concepts of building design are therefore not static rules – they are the playing field on which the architecture of tomorrow will be negotiated. And they are the touchstone by which the seriousness of any sustainability strategy is demonstrated.

Conclusion: No progress without basic concepts – building design remains a top priority

The basic concepts of building design are the foundation on which every innovation, every digitalization and every sustainability strategy is built. Those who master them are able to design buildings that are not only beautiful, but also robust, efficient and sustainable. The differences between Germany, Austria and Switzerland provide valuable impetus – but the global architectural discourse shows that the challenges are similar everywhere. Digitalization is changing the rules of the game, but it is not replacing basic knowledge. Anyone who neglects the basics of building design will quickly be caught up in reality. And anyone who believes that sustainability can be achieved without construction know-how will only end up producing refurbishment cases. The architecture of the future needs both: solid knowledge and the courage to change. The basic concepts of building design are not a compulsory exercise, but the key to the building culture of the 21st century.

Wood – an urban material ?

Building design

Wood in the cities – there are a number of arguments in its favor. The material is CO2-neutral, has good insulating properties and is a renewable raw material. Architect and civil engineer Wolfgang Winter would design any new building out of wood. Sufficient material and the technology to build upwards are available.

Wood in the cities – there are a number of arguments in its favor. The material is CO2-neutral, has good insulating properties and is a renewable raw material. Architect and civil engineer Wolfgang Winter would design any new building out of wood. There is enough material and the technology to build upwards.

Baumeister: Mr. Winter, we are confused: on the one hand, we hear about a renaissance in timber construction, but on the other hand, timber construction in the city has declined. Which is true?
Wolfgang Winter: A stable market segment has emerged for single-family houses in Central Europe. In multi-storey construction, it is more complicated: in the 70s to 80s, i.e. after the war, there was a market share of zero. In Austria, Germany and Switzerland, state-subsidized campaigns were created at the time to accommodate the returnees from Russia – building was done with wood. These campaigns caused the market share to rise to five percent in the short term. The fact that this figure is now weakening again is due to the lack of funding. The question is: Can ecological measures that cost more than concrete construction be justified at all? This brings up the concept of affordable housing, because expensive construction is not socially sustainable. Then we just build in concrete again. From this perspective, social sustainability excludes ecological sustainability.

B: Does timber construction necessarily have to be more expensive?
W W: In the short term, yes. A cubic meter of concrete costs 50 euros. Wood, on the other hand, costs 400 euros per cubic meter. So if you replace concrete with wood in an equivalent construction project, it is more expensive. That is of course a disadvantage of wood.

B: Where does this big price difference come from?
W W: A cubic meter of tree, as it comes from the forest, costs 100 euros. The price is determined by the forester who cuts the wood and the forest owner who waits 100 years for the tree to grow. If the tree is sawn down, 50 percent is lost through the waste products. This means that a cubic meter costs 200 euros. The wood then has to be dried and glued, tempered and quality sorted. This is always a high cost for a natural product.

B: The solution?
W W: You have to build intelligently. For timber construction in the city, you need a well thought-out system and a quality-assured product. This is not possible in this DIY niche with a regional, “cute” timber construction culture. For large-scale industrial projects with 200 residential units that need to be completed within six months, you need prefabricated products. In terms of price, timber is competing with in-situ concrete poured on site. At the moment, it is still losing this battle.

B: So timber has a lot of competition. Until 1800, things were different – every building was made of wood, at least in part. When exactly did the turning point come?
W W: Until 1800, all construction was “self-build”. People built with the materials that were available on site. Carpenters and bricklayers built without architects. A big break came with industrialization. The crafts disappeared. The railroad, steel and cement arrived.

B: What’s more, in the 19th century there was simply no more wood…
W W: That’s when the laws for sustainable forestry were introduced. From the second half of the 19th century, they stipulated that if a tree was felled, two new ones had to be planted.

B: So we would have enough wood again today. And the “paperless office” will surely ensure even more wood…
W W: The paper thing is not so easy to conclude. In fact, the yields from forests have increased enormously. This is due to properly managed forests. Until the 18th century, yields were five cubic meters per hectare. With forest management, the figure climbed to 10-15 cubic meters per hectare. Due to climate change and the high CO2 content in the air, forests are becoming even more productive.

B: So we would have enough wood to theoretically build entire cities with?
W W: Yes. There is more wood growing than we need. If we wanted to, we could build every new construction project in wood.

B: How high could we build with wood?
W W: Wood has a compressive strength of 30-40 newtons, concrete also has 30 newtons. Of course, it has a lower tensile strength than steel. But this can be compensated for with a higher cross-section. And timber is still relatively light. Pure timber buildings of up to ten storeys are technically possible without any problems, even when fire protection requirements are taken into account. Fire protection is actually a question of escape routes and access and not the combustible material.

B: Especially when we’re talking about urban areas, isn’t there a great risk of fire spreading from one building to another?
W W: Every fire is started by mobile fire loads – the furniture, the curtains. Wooden buildings don’t burn any more than other buildings. Wood does not ignite more quickly, nor is the risk of a fire starting greater than with other building materials. The most important fire protection measure is the escape routes.

B: Timber construction seems to reach its limits at ten storeys. Why then want to build even higher? Shouldn’t we think about the material according to its use?
W W: The tensile forces are the problem. But you can use timber steel for that.

B: Wooden steel?
W W: When we talk about timber-steel construction – steel clad with wood – then it’s the same principle as with reinforced concrete: you have a large cross-section consisting of compression elements, in this case made of wood, and inserted flat bars or angles that absorb the tension. From a structural point of view, all skeleton structures that are currently made of reinforced concrete could be made of wood.

B: What are the biggest advantages of timber in the city?
W W: Wood is an excellent raw material that can be used to make various products. It is easy to process. It also has low thermal expansion due to its high porosity. With other materials, you have to leave more space during installation, or the adhesive has to compensate for the expansion. Wood also has good thermal insulation properties. The advantages in the city lie in building gaps and extensions. The material is light and can be lifted into urban structures by crane.

B: Another major advantage of timber in the city is the high degree of prefabrication. Does this impose restrictions on the design?
W W: I think you can design very freely with wood. Nowadays, wood is machined and glued together. Robots mill out holes and join the wood together. So you can produce parts industrially and individually.

B: No disadvantages?
W W: Of course, it’s clear that if an architect builds monolithically beforehand, this allows for different building forms and requires different thought structures than if you put together an additive system from rods. Prefabricated timber construction requires a certain level of awareness on the part of the architect. If the architect has this knowledge, however, there is certainly freedom of design. The prefabrication of timber and steel is equivalent in the construction process. But wood has a few additional advantages.

B: Sustainability, for example. However, the word is now used everywhere. Has it lost any of its strength as an argument for timber construction as a result?
W W: A lot has been smuggled into the term sustainability: architectural quality, beauty and ecology. Now we no longer talk about sustainability, we talk about resource efficiency. Timber construction itself is clearly resource-efficient. And since we change our building fabric in relatively short cycles, resource efficiency also means what the material makes possible in terms of later use. The monolithic cast construction cannot be dismantled and rebuilt elsewhere. Steel and wood are easier to recycle.

B: Do you think that in a world surrounded by technology, we are longing for a natural building material?
W W: Yes, that is certainly part of it. On the one hand, there is this useful timber construction, but it doesn’t claim to be a statement. Our urban buildings have many half-timbered structures that were subsequently clad. Today, of course, things are different. Since concrete was the building material of the 20th century, if you offer an alternative, you also have to work with a feeling: We now live in a material that is closer to nature. But that will certainly only remain a niche. Eco-awareness is a decisive factor for a maximum of 20 percent of the population. The others don’t care if they live in a concrete building.

B: You said that concrete was the dominant building material of the 20th century. Is wood the building material of the 21st century?
W W: Wood has everything it takes to become the building material of the 21st century. Concrete was the building material of the 20th century, especially in Europe. This has to do with our specific history, with the Second World War. You could argue that the population’s growing environmental awareness is the basis for wood becoming the material of the 21st century. But, of course, you have to see how strongly wood is being fought over by the forestry, paper and pellet industries. The competing players for this natural material must agree that it makes the most sense to build with wood.

The poetry collection "Schiefern"

The poetry collection “Schiefern” by Esther Kinsky explores the analogy between human memory and metamorphic rock – a sensual search for the lifeless. On the map, they are small patches off the west coast of Scotland, so small that it is easy to overlook them. You have to seek them out specifically to find them. You don’t just come across […]

The poetry collection “Schiefern” by Esther Kinsky explores the analogy between human memory and metamorphic rock – a sensual search for the lifeless.

On the map, they are small spots off the west coast of Scotland, so small that it is easy to overlook them. You have to seek them out to find them. You don’t just stumble across them. The Inner Hebrides of Scotland, a group of islands at the top of the British Isles, are a popular travel destination. Those who come here long for the original, the wild, the rugged. For the salty wind that catches hair and clothes and makes them stiff. For the Atlantic, its waves crashing against the black rock. Gneiss. Granite. Basalt. Slate.

Esther Kinsky, translator and poet and 2018 for “Hain. Geländeroman” in the fiction category at the Leipzig Book Fair, has dedicated a volume of poetry to slate and the region where the sedimentary rock was mined for centuries with the simple yet telling title “Schiefern”.

The quarries on Slate Islands are still there, as are the remnants of a now defunct industry. Kinsky embarks on a voyage of discovery and wraps her observations of nature in words that are enigmatic to decipher and carry us away to the remoteness of the Inner Hebrides, to the black, raging sea, above which the reader floats like an invisible person in the mental space that Kinsky spins with her words.

It is precisely there, in this space of thought, that the analogies between something thoroughly lifeless and human can be found. There are only a few people in this three-part volume, but it is not lacking in humanity. In fact, it is quite astonishing how sensually it is possible to write about waves carrying spray and “plates with a / surface like petrified quiet waves” without slipping into kitschy romanticism.

“Nature Writing”

Nature has been tempting writers to write about it as the main protagonist since the 18th century. In Anglo-Saxon, “nature writing” is the name given to lavish literary descriptions of trees, meadows, flowers and cloudbursts. In German, the term “Naturpoesie” or “nature poetry” has become commonplace. Esther Kinsky has stood out in literature for years with such nature poetry.

In 2013, she weaved four cycles of poems about decay and growth in “Naturschutzgebiet” (Nature Reserve), based on a neglected city park. If Kinsky’s work is now categorized as “nature writing”, she is happy to contradict this. In an interview with Deutschlandfunk radio, she once said that she did not see herself in the tradition of nature writing. This term is too diffuse, too sprawling in terms of what it encompasses and what it does not. “Nature writing” can be anything, she says. So why not her latest work “Schiefern”, one might ask?

The layers of time

Early on in “Schiefern”, the word “memory” is used “as a space of absences, moved by the transparent hand of unpredictable synapses and imponderable shifts of deposits in the slowly emerging and deepening furrows and folds of the brain”. Kinsky is concerned with the layers of time that accumulate over memories. At first very gently, then more clearly, she draws linguistic parallels between human memory and the preserved history on the surface of the rocks, which the tides and times have passed by over millions of years.

The past is preserved in the stone, it only has to be read from its wrinkles, as if the stone were an old, cherished old man whose weathered face bears the traces of life. Kinsky writes of “signs without hand or foot / in the stone to which no one / knows how to make a rhyme / but the greatest possible past”.

“Schiefern” could be the modern sequel to Adalbert Stifter’s 1853 short story “Bunte Steine” and join the ranks of “Granit”, “Kalkstein” and “Turmalin”. But as treacherously idyllic as Stifter’s detailed, Biedermeier-like depictions of nature are, Kinsky’s description of the Slate Islands is just as uncharitable. The coolness of the surroundings snows through her words. There is a harshness in them that you don’t want to imagine without.
