The winning project of the German Sustainability Award for Architecture 2022 was announced at the beginning of December 2021. This year’s prize goes to the “Einfach Bauen” project in Bad Aibling. Read all about the project here.

Germany’s most prestigious architecture prize for sustainability (we already reported here: Sustainability Award Architecture 2022) goes to Bad Aibling this year. Here, the Munich-based firm Florian Nagler Architekten built three research houses with identical floor plans under the motto “Simply Building“. This motto perfectly reflects the premise under which the buildings were designed. The houses are designed to be as simple as possible, using few and unmixed materials. This saves construction time and costs. If necessary, the materials used can also be easily recycled.

The three “Einfach Bauen” houses are located on the B&O Group’s park in Bad Aibling. Initially, they look like two peas in a pod. Each of them offers space for eight residential units. On closer inspection, however, it becomes clear that the buildings are constructed from different materials. Wood, concrete and brick were used, each in single-shell and monolithic construction. In other words, without composite materials, which contain plastic, for example, and may make recycling impossible.
The concrete house is made of unreinforced insulating concrete. To avoid the mix of materials, the windows of the concrete building are also curved. The high thermal storage capacity of the concrete also makes the building climatically inert, so that no insulation layers are required. The timber house consists of three-layer wall elements made of cross-laminated timber layers. Inside the wooden walls, air cushions provide the necessary insulation, and they are also clad with rear-ventilated spruce boards. Additional layers of insulation are therefore not required here either.

Building services: as simple as possible

The “Einfach Bauen” houses in Bad Aibling are also as simplified as possible when it comes to building services. The building structure and the technical system are also as separate as possible. Pipes, for example, are mostly laid on the surface. This allows for quick repairs if necessary. Instead of complex underfloor heating systems, conventional radiators are used, which can be easily replaced. Architect Nagler also dispenses with complicated ventilation technology in the research houses. Instead, simple window rebate ventilators ensure the minimum air exchange in the apartments when the windows are closed.

On November 18, 2023, the exhibition “Tsuyoshi Tane: The Garden House” will open in the Vitra Design Museum Gallery. It is dedicated to the recently built Tane Garden House on the Vitra Campus.

The Garden House by Japanese architect Tsuyoshi Tane is the latest building on the Vitra Campus and the first to be designed with the climate crisis in mind. The impetus for its construction came from Rolf Fehlbaum, Chairman Emeritus of Vitra, in 2020. In a letter to Tane, he explained that the Tane Garden House, together with the surrounding Oudolf Garden, should be the “first manifestation of a greater awareness of sustainability” on the Vitra Campus. It is important that the materials, working methods and usage methods used meet high ecological standards.

The Tane Garden House has a relatively small footprint of just 15 square meters and serves both as a lounge for the gardeners on the site and as a viewing platform for visitors to the campus. The platform offers an elevated view of the surrounding Oudolf Garden. The facility was developed in a trial-and-error process in which many different options were explored in search of the essence of the site.

The garden house is a typical example of Tsuyoshi Tane’s way of working. His projects are always preceded by intensive research into the local conditions. The exhibition in the Vitra Design Museum Gallery shows how the new building emerged from such research.

Like an archaeologist, Tane embarks on a kind of journey of discovery and searches for the essence of each place – he even describes this process as archaeology, the “archaeology of the future”. In doing so, he primarily explores the use of traditional materials and the regional craftsmanship in dealing with them. Tane also uses the term “above ground” to describe renewable products such as reeds or wood. This contrasts with “underground materials”, which are heavily overused raw materials. Although Tane was inspired by the historical buildings in the Swiss open-air museum Ballenberg to use the materials that make up the garden house, his own structure was built using regional production techniques and in collaboration with local craftsmen. The aim was to generate the smallest possible CO2 footprint overall.

The exhibition in the Vitra Design Museum Gallery presents, among other things, precisely these materials as components of the building: from the traditional thatched roof and the well trough made of logs to the binding and knotting techniques of ropes used for the staircase balustrade. Visitors will also find architectural models as well as models of individual building elements, drawings of the building and evidence of collaboration with local craftsmen. The entire development of the building can be traced on the basis of over a hundred models and mock-ups that have gone through several experimental stages. The exhibits show Tane’s intensive engagement with the typology of the building and his playful approach. The Tane Garden House is a building that represents an experimental study in contemporary and ecological construction. The exhibition consists exclusively of the materials used in the development process.

The exhibition is accompanied by the publication “Tane Garden House”. It conveys Tane’s unique architectural approach, his discussions and exchanges with craftsmen, builders and others involved in the process using statements and drawings, prototypes and sketches, models and materials.

The exhibition will open on November 18, 2023 and will run until April 21, 2024, inviting anyone interested to come and see for themselves.

Until recently, another interesting exhibition was on show at the Vitra Design Museum: Everything about “Garden Futures” here.

Art in shape – The stone in January 2025

Jo Kley's "Bull" is one of more than 100 sculptures that the freelance artist has created in Germany and 20 other countries around the world. Kley has been carving sculptures out of natural stone for around 25 years, using them to bring irrepressible energy into solid forms. Jo Kley regularly takes part in symposia and has created numerous works for public spaces. The artist lives and works in Kiel. © Bernd Perlbach

In the first issue of the new year, we invite you to rediscover the ancient excavation sites of Pompeii through the eyes of renowned architectural photographer HG Esch. He shows the city in unprecedented clarity. We will also be presenting impressive sculptures made of natural stone that artist Jo Kley has created in recent years and taking a closer look at the mandatory e-invoicing that will apply to companies from 2025.

Trade fair in Munich

Right at the beginning of the year, another trade fair is on the agenda: BAU 2025. It could be worth coming to Munich, because the program reads promisingly. The building of the future is right at the top of the trade fair organizers’ agenda. Companies from the natural stone, ceramics and tile sectors await you in Hall A4.

Pompeii from above

From page 6 onwards, we invite you to take a completely new look at the ancient excavation sites of Pompeii with us. Renowned architectural photographer HG Esch and his team have embarked on a literally “historic” journey, during which spectacular drone photos were taken. They show the structures of the ancient city with unprecedented clarity.

Award-winning sculptures

After breathtaking photographic art, from page 14 we show impressive sculptures made of natural stone that artist Jo Kley has created in recent years. He remains true to his original profession as a stonemason and stone sculptor. Kley has already given advice and support to the winners of the “DMH” and “Gute Form” competitions twice during a workshop. In this way, he is preparing the ground for the artists of tomorrow.

Maoi in Berlin

Our author Dr. Inge Pett found out for you how a moai from Easter Island ended up in Berlin’s Gardens of the World. The replica of such a huge sculpture made of tufa stone had literally been growing grass for 25 years. Find out what the Moai are all about from page 30 onwards.

Electronic invoices

From page 48, we turn our attention to a topic that may be on the minds of many of you: e-invoices. They will be mandatory from 2025. Our author Marian Behaneck explains what this means for companies and what details you should pay attention to when creating, receiving, processing and archiving electronic invoices.
