It’s the little things that make good products into very good products: a membrane, a hidden hinge, the look. The latter in particular is one of the main criteria for architects when choosing the right solution. After all, architects and specialist planners expect the technology to work and the material to meet individual requirements. And so most companies continue to attach great importance to design aspects – without neglecting function and additional benefits.

Glass doors with maximum minimalism

With its unmistakable design claim, Josko has created new, extraordinary interior doors: the glass doors of the MET-Loft series. They are characterized by their uncompromisingly reduced design and are pure perfection for people with a high aesthetic sense. The puristically elegant glass doors are meticulously crafted and feature discreet, clear lines. With extremely slim frames of only 15 millimetres face width made of easy-care aluminum and concealed fittings without a visible lock case, they underline the claim of modern architecture: minimalism for advanced users.

Another example of Josko’s minimalist design language is “ONE”, the uncompromisingly symmetrical and slim window with a purist look. What both products – ONE and MET Loft – have in common is that they received the “Red Dot Award” even before their market launch.

For a more industrial look, the glass doors in the MET Loft series can also be designed with discreet transom doors. Depending on the style of living and taste, there are models with different glazing bar spacings and glass with textures and tints. Thanks to the innovative locking magnet and the shell handle specially developed by Josko, which is discreetly concealed in the aluminum frame, no lock case is visible on the glass doors. The discerning eye will also look in vain for hinges here, as they are concealed in the MET frames. Beauty is what you don’t see.

Product: MET-Loft glass doors
Manufacturer: Josko Fenster und Türen GmbH, A-Kopfing
Features: Sliding and hinged doors, powder-coated aluminum frame with 15 mm face width, invisible frame, concealed hinges, with and without glazing bars, glass also with textures and tints, in three aluminum shades: light bronze, medium bronze, and black

Aiming high thanks to airtightness

Strong wind loads, building movements, driving rain and high noise levels are major challenges for the tightness and comfort of sliding systems in high-rise buildings. The solution lies in the seal. And that is why Schüco has brought a competent partner on board for the development of the “AS AL 75” single-track sliding system: Air-Lux. Their patented pneumatic sealing technology with membrane function meets these high requirements – and works with air.

When the sliding system is closed, air is pumped into the seal by pressing a button. The gap between the sliding sash and the frame closes so that the sliding system is 100 percent sealed. The air can escape from the seal by pressing the button again: The sliding element can now be opened and closed smoothly again.

The filigree aluminum profiles of the Panorama Design windows can be installed flush with the floor and ceiling as well as laterally in the reveals, so that a level threshold ensures barrier-free access. The interior thus opens seamlessly to the outside. Large elements can be installed up to a height of six meters and a width of up to eight meters and can optionally be operated with a concealed drive. The integration of the Schüco AS AL 75 sliding system into all standard building management systems offers a high level of convenience. Control with a mobile end device is also possible.

Product: “AS AL 75” sliding system
Manufacturer: Schüco International KG
Properties: 75 mm basic depth, for high-rise buildings, wind loads up to class C4/B4, watertightness up to class E1500, burglar resistance up to RC 3, sound insulation up to 44 decibels

Blunt is trump

Discreet design, straight lines and purist solutions continue to define the current architectural design trend. This is why the demand for building elements in which technically functional elements are formally integrated is also increasing.

Flush doors with clear lines, aesthetic shadow gaps and harmonious edges meet this demand within modern architecture and combine functionality and design at the highest level. One example of a particularly clan look combined with a very high functional standard is the flush-fitting “T30-1/2-FSA-Teckentrup 72 ST” fire protection door. The door element is available with one or two leaves and the door leaf is 72 mm thick. The door and gate specialist Teckentrup has also developed the “Designprofil-FB” for the uncomplicated realization of flush-fitting requirements. This frame solution enables cost-optimized and simple installation of doors with a flush look. The profile – available for Teckentrup doors in the “62 series” – is easily combined with standard frames. With a block frame, the door is flush with the wall, while with a corner or U-frame, the door leaf itself is flush with the frame and at the same level as the skirting board.

Both series offer numerous additional functions – such as smoke, sound and burglary protection, thermal insulation – as well as different surfaces and glazing.

Manufacturer: Teckentrup GmbH & Co KG, Verl-Sürenheide
Product Teckentrup 72 ST: Door leaf 72 mm, door leaf/frame rebate-free and flush with the wall, single and double-leaf, sound-insulating up to 42 dB, burglar-resistant up to RC 2 (to DIN EN 1627)

Product design profile-FB: Door leaf 62 mm, depending on frame type flush in the wall or in the frame, 1- and 2-leaf, sound-insulating up to 43 dB, burglar-resistant up to RC 4 (according to DIN EN 1627)

Sound architecture used to be a question of acoustic planning and good taste. Today, it meets high-tech, artificial intelligence and spatial culture – and the epicenter of this development is, of all things, the record player. The record player, once a symbol of nostalgia and analog chic, is becoming a blueprint for new thinking in terms of interior design, material ethics and digital transformation. Anyone who thinks that only music lovers will get their money’s worth here is underestimating how much sound design will shape the architecture of tomorrow – and how little room there is for excuses.

The revival of the record player: analog icon in the digital age

In recent years, the record player has experienced a renaissance that goes far beyond simply rehashing nostalgia. In Germany, Austria and Switzerland, the device has advanced from a dust catcher of its parents’ generation to a statement object that electrifies design lovers, architects and material researchers alike. It is not uncommon for the record player to be presented in the relevant magazines and showrooms as the epitome of deceleration, material awareness and value. But anyone who only senses retro charm and vinyl romance here is overlooking the technical and creative explosive power inherent in this topic. This is because current record player design is a laboratory for innovations that have a far-reaching impact on the disciplines of room acoustics, digital technology and sustainable materials.

What sets the DACH region apart is the way it bridges the gap between traditional manufacturing and high-tech engineering. Companies such as Clearaudio in Bavaria, Pro-Ject in Austria and Thorens in Switzerland combine traditional craftsmanship with precise measurement technology and digital control. Turntables are not only built here, they are virtually composed: Enclosures made of sustainable woods, chassis made of recycled aluminum, tonearms made of carbon or titanium – all in the service of a sound that not only wants to be heard, but spatially experienced. This makes the record player a touchstone for the question of how design, technology and sustainability actually go together.

The renaissance of the record player is also reflected in architecture. More and more planners and interior designers are integrating high-quality audio technology as an integral part of their designs. Not as an afterthought, but as an integral part of the room concept. As a result, sound is becoming an architectural category, comparable to light, room climate or materiality. Anyone planning a record player in a residential or cultural building project today not only has to deal with technical details such as resonance damping and freedom from vibration, but also with questions of room acoustics, furnishings and atmospheric effect.

Turntable design therefore sets new standards for the interaction between technology and space. It forces architects and clients to throw old certainties overboard – for example, that sound is primarily a question of reverberation times and absorber panels. Instead, the focus is shifting to the question of how sound and space can mutually determine, reinforce or irritate each other. And this is where the real innovation begins: the record player becomes a catalyst for an architecture that sees sound not as a disruptive factor, but as a resource.

But digitalization does not stop at the record player. Intelligent motor controls, smart sensor technology and AI-based sound optimization are no longer a utopia, but standard in high-end devices. Anyone who believes that this is only about analog purism should take a closer look at the latest developments: From vibration-decoupled plinths to automated sound calibration – today’s record player is part of a networked ecosystem that sets new standards for sound and room architecture.

Digital transformation: when algorithms guide the needle

Digitalization has not abolished the record player, but rather breathed a second life into it. Where the turntable used to be adjusted by hand and the tonearm balanced with dexterity, sensors and algorithms are now taking over. Smart turntables measure resonances, analyze room acoustics and adjust settings in real time. The AI decides whether the bass is too spongy or the treble too sharp – and makes corrections before the human even reacts. What sounds like a tech gimmick is actually a paradigm shift: the interface between sound technology and architecture is becoming a data space that opens up new possibilities for planning, control and optimization.

Progress in the DACH region varies. While some manufacturers are focusing on complete digitalization – for example with streaming functions, app control and cloud connectivity – others are staying true to the purist approach and deliberately building analogue machines with digital add-ons. The debate between “back to basics” and “smart everything” has long since flared up, and it is also reflected in the architecture: should the sound space be fully automated, or is there room for deliberate imperfection? Can AI optimize sound, or is the human ear the final authority?

For architects, planners and engineers, this means that anyone who takes sound architecture seriously must deal with digital technologies – from sensors and signal processing to integration into smart building control systems. Collaboration with acousticians, sound designers and IT specialists is becoming a mandatory task. Digital tools such as BIM, parametric acoustic models and AI-supported simulations are forcing their way into the design phase and changing the job description forever. Those who turn their backs here are relinquishing control over sound and atmosphere – and leaving it to algorithms and manufacturers.

However, digitalization not only brings with it technical challenges, but also ethical questions. Who actually owns the data that the smart record player collects about the room and user behavior? How transparent are the algorithms that optimize the sound? And how can commercial interests be prevented from colonizing the architecture of listening? The danger of commercialization is real: what is sold as progress often turns out to be greenwashing or an attempt to force user loyalty through proprietary systems.

Critical reflection is required here. If you want to help shape the digital transformation of turntable design, you have to think about technology, architecture and society together. The great opportunity lies in establishing sound as an open, designable category – as a field that mediates between craftsmanship, high-tech and spatial culture. However, this presupposes that the industry does not allow itself to be driven by algorithms and marketing departments, but instead leads the discourse with self-confidence. Then digital sound design will actually become a contribution to the building culture of the future.

Sustainability and materiality: the sound of the future is green

In times of resource scarcity, climate crisis and growing environmental awareness, the question of sustainable turntable design is becoming a crucial issue for architects and manufacturers. The good news is that there are pioneers who are focusing on recycling, the circular economy and low-emission materials – setting new standards for audiophile technology and interior design in equal measure. The bad news is that the road is rocky and greenwashing is lurking everywhere.

Turntables are not disposable products, but investments that last for decades. However, the ecological footprint is not only created by the material, but in the entire value chain: from the extraction of raw materials to production and energy consumption during operation. Manufacturers such as Pro-Ject and Clearaudio are increasingly relying on wood from certified forestry, recycled metals and solvent-free paints. Others are experimenting with biopolymers, carbon residues from aviation or 3D-printed components in order to minimize weight and resource consumption.

For architects and planners, the choice of turntable thus becomes a question of material ethics. Anyone integrating a high-end turntable into a sustainable building must check whether the product is ecologically justifiable – and how it is compatible with other building materials. Resonance behavior, emission values, recyclability and durability are becoming new decision-making criteria. This sounds like bureaucratic overkill, but in reality it is a necessary paradigm shift: material selection is becoming a sound policy, and sustainability an integral part of architectural listening.

The debate about greenwashing is anything but academic. Many manufacturers advertise with slogans such as “natural sound” or “environmentally friendly production”, but a look behind the scenes often reveals a different picture. Transparency is rare, and reliable life cycle assessments are usually sought in vain. Architects and builders who fail to ask questions are complicit in an industry that sees sustainability primarily as a marketing strategy. The solution: cooperation with independent testing institutes, disclosure of supply chains and the development of common standards for sustainable sound design.

However, sustainability is not just a question of materials, but also of usage behavior. A durable record player that is repaired and maintained over decades beats any disposable loudspeaker, however green it may be. Reusability, modularity and ease of repair are becoming new virtues – and also raise the question of a culture of listening that focuses on appreciation rather than consumption. This makes sustainable turntable design a touchstone for the credibility of the entire industry – and a role model for other areas of building and product culture.

Sound as an architectural resource: rethinking interior design

Record player design has long been more than just product development – it is a source of inspiration for interior architecture itself. Hardly any other object forces planners to think so consistently about the relationship between sound, material and space. The integration of high-quality audio technology calls for spatial solutions that go far beyond mere “placement”: Sound diffusion, reflection, resonance and damping strategies must be considered if the sound is to develop its full architectural effect.

In current designs for living, cultural and working spaces, there is a trend towards sound architecture that goes far beyond traditional acoustic planning. Planners are working with parametric acoustic models, intelligent controls and adaptive materials to create spaces that not only allow sound, but actively stage it. The record player becomes the starting point for a new discipline: soundscaping as a designable dimension of urban and architectural identity.

This requires specialist technical knowledge that was previously more at home in recording studios than in architectural offices. Room acoustics, vibration control, material resonance and sound fields are no longer exotic fringe issues, but are becoming an integral part of the design process. If you don’t upgrade here, you run the risk of the architecture being designed without the user in mind – and the sound ending up in the corner as an annoying reverberation. The professional handling of sound technology, from the selection of the turntable to the fine-tuning of room acoustics, is thus becoming a new key skill for the industry.

But beyond all the technology, the crucial question remains: how can sound become an architectural resource without degenerating into an end in itself? Visionary approaches focus on understanding sound as an atmospheric design tool – as a medium that creates identity, generates community and emotionally charges spaces. Examples from Japan, Scandinavia and the USA show how sound installations, interactive sound surfaces and adaptive room acoustics can shape the character of buildings. The DACH region has some catching up to do here, but also enormous potential: concepts are emerging between the Bauhaus tradition and the digital avant-garde that combine sound and space in new ways.

Ultimately, it’s about nothing less than the democratization of listening. The record player, as mundane as it may seem, becomes a symbol for an architecture that appeals to all the senses and enables new forms of coexistence. Those who understand sound as a resource design spaces that not only function, but also inspire – and that finally fulfill the promise of building culture in the 21st century.

Global discourse, local practice: connected or left behind?

The discourse on turntable design and sound architecture has long been international. In the USA, the UK and Japan, audiophile spaces and soundscapes are an integral part of the architectural avant-garde. Digital tools, AI-based simulations and sustainable material innovations are not seen there as a gimmick, but as a natural part of the design process. The question is: can the DACH region keep up here – or will it remain stuck in its analog snail shell?

As is so often the case, the reality is ambivalent. On the one hand, there are outstanding technical innovations and a rich tradition of workmanship that sets international standards. German, Austrian and Swiss manufacturers are in demand worldwide when it comes to precision, durability and sound quality. On the other hand, there is often a lack of courage for radical innovation, openness to interdisciplinary collaboration and the integration of digital technologies into everyday architectural practice. The fear of loss of control, misuse of data or technocratic overload slows down development – and ensures that visionary concepts often get stuck in pilot projects.

Debates about data sovereignty, algorithm transparency and sustainability standards are certainly taking place in the DACH region – but mostly with a tendency towards overregulation and perfectionism. While prototypes have long been tested and open interfaces developed elsewhere, people in this country are still looking for the ideal specifications. As a result, the global discourse continues, while local practice remains stuck in the small details. This does not have to remain the case, but it does require a change in mentality – away from vested interests and towards creative openness.

The ability to connect with international developments is not a question of budget, but of attitude. Anyone who sees sound architecture and turntable design as a topic for the future must take the plunge into the deep end – with interdisciplinary teams, open data models and a culture of experimentation. The DACH region has all the prerequisites to play a leading role here. It just has to want to – and be prepared to question familiar patterns.

The end result is the realization that sound architecture is far more than a technical side issue. It is about the future of building culture, about the question of how we want to experience, use and design spaces. Anyone who pats themselves on the back because the record player in the showroom shines has understood nothing. Only when sound, space and technology are considered as a unit can architecture be created that is worthy of the name – and that can also hold its own on a global scale.

Conclusion: record player design as a blueprint for the architecture of tomorrow

Turntable design is far more than just a fashion accessory for audiophiles. It is a laboratory for innovation, a testing ground for sustainable materiality and a catalyst for the digital transformation of spatial architecture. Anyone who takes sound seriously must rethink technology, materials and space – and be prepared to question old certainties. The DACH region has the potential to set international standards here. But this will only succeed if the industry dares to strike a balance between tradition and innovation. Those who see the record player as an architectural resource today will shape the building culture of tomorrow – and ensure that rooms are not only built, but also heard.

2018 marks the 20th anniversary of the completion of Potsdamer Platz in Berlin. The redesign of the square, which had shaped the center of Berlin since the 18th century, was to contribute significantly to the merging of East and West after reunification. The architects Renzo Piano and Christoph Kohlbecker were able to help create a new district with their part in the development of the square.

On the one hand, they relied on buildings that are partly tall and partly wide, partly at an acute angle or arranged in a circle like the cinema complex. The dynamic silhouette of the streets was given a unique character by the natural ceramic façades of the “Terrart” façade system from NBK. Designed in earthy, sand-colored natural tones, these curtain façades take up the classic Berlin stone façades in an innovative interpretation. With their large-format wall panels alternating with so-called baguettes – a series of long ceramic rods – the buildings appear delicate despite their size. Transparent and closed surfaces demonstrate the enormous flexibility of the system while at the same time meeting high aesthetic standards.

The photo motifs from 1998 and 2018 also show that the buildings look exactly the same today as they did in the 1990s. The natural material ceramic, with its temperature, weather and corrosion resistance, still proves its valuable appearance after many years. Potsdamer Platz thus has the best prerequisites to carry its attractiveness and architectural lighthouse function in the center of Berlin into the future.
