Beauty is not an addition. It is the only reason buildings outlive their original function.

Starting Point
Balingen, in the Zollernalb district on the Swabian Jura: an established urban neighbourhood of fine grain, modest scale and a quiet sense of dignity. Into this context, PKF – an expanding audit and advisory firm – sought to grow. The ambition was not simply to create more office space, but to establish a place capable of carrying the company’s identity: a campus.

The starting point was an existing ensemble that had reached its limits – spatially, functionally and atmospherically. The brief was to extend it. Yet the more fundamental question ran deeper: how can an established place be expanded without overwhelming or erasing what is already there?

Setting and Urban Approach
The site sits at the heart of a residential fabric that tolerates nothing ostentatious. At the same time, the project required presence: an architectural confidence that does not intimidate, but welcomes.

The response was not a singular grand gesture. It was its opposite: four distinct buildings forming an ensemble without becoming a façade. Each house has its own address, its own character, its own human scale.

At the centre lies a park-like garden – not residual greenery or a mandatory open space, but the true heart of the campus. From here, the site opens towards the landscape and the characteristic hills of the Swabian Jura. Lavender flowers in front of glass façades. Mature trees stand alongside dark Corten steel. Nature is not a decorative motif here; it is a co-author of the architecture.

Architectural Concept
The guiding idea was never simply an office building. It was a landscape for work – a term that carries more meaning than it initially suggests. Four houses, one centre, one park. Existing fabric and new construction are not treated as opposites, but as parts of a dialogue.

The new buildings take up the scale and atmosphere of the existing ensemble without imitating it. They continue its story through contemporary means. The result is a transition without rupture: a continuity that can be felt before it can be named.

The structural system of the new buildings is expressed through vertically arranged fins in dark patinated steel – precisely rhythmical, yet never decorative. They filter daylight. They create depth. They make the construction visible, because material honesty is a value in itself.

Inside, a spiral staircase in polished steel connects two floors, while transcending its purely functional role. It becomes a sculpture, the backbone of the building, a point of conversation. Alongside it, a timber library wall introduces warmth and quiet into an interior otherwise defined by glass and steel. Contrast becomes a method.

Material Palette
Every material was chosen because it had something to contribute – and nothing more.

Dark patinated steel defines the louvred façade: timeless, robust and capable of becoming more beautiful with age. Dark brick forms the opaque wall planes – raw, honest and deliberately set against the transparency of floor-to-ceiling glazing, beyond which the Swabian Jura becomes the project’s defining office panorama.

In the landscape, natural stone, timber and Corten steel form a palette that responds to the changing seasons and gains life from them. The cafeteria – with its warm oak slatted ceiling, solid timber tables and full-height glazing towards the garden – is not an ancillary space. It is the social heart of the campus.

Places where people genuinely want to gather must be beautiful. This is not merely a matter of taste. It is a matter of effectiveness.

Beauty as a Sustainability Strategy
The architecture of the PKF Campus does not pursue sustainability in the conventional, highly marketable sense. There is no Cradle to Cradle certification, no staged display of photovoltaic panels – although photovoltaics are, of course, part of the project – and no embodied-carbon balance presented as a selling point.

Instead, the project advances an older and more radical proposition:

Buildings are used and loved over the long term when they are beautiful.
Not because they are efficient, but because they move us.

Beauty is the deepest form of sustainability. A building that is loved will be cared for. It will be maintained. It can outlive its original purpose because people will be reluctant to let it go.

The PKF Campus was not designed for the next certification. It was designed for the next generations. At a time when architectural discourse is often dominated by trends, this represents a quiet yet unequivocal position: substance over effect. Atmosphere over equipment. Conviction over hype.

Delivery and Collaboration
A campus like this does not emerge from a briefing. It grows from a conversation – a long, occasionally uncomfortable, but always serious dialogue between client and architect.

PKF knew what it wanted: a place that creates identity, attracts and retains employees, and does not merely reflect corporate culture but actively shapes it. What it did not yet know – and what architecture must be able to reveal – was what such a place should look and feel like before it exists.

This act of translation, from aspiration to reality, is the essence of architecture. It requires trust. And when it succeeds, it produces something greater than the sum of its parts: a place that stays with you.

The PKF Campus in Balingen is such a place.
