From the architect. Danish law firm Horten wanted their new headquarters to present itself in a contemporary as well as classical and solid way. Our solution was to design a modern office with a new interpretation of the classical stone-clad facade.

Inside, the building appears light and open with a flexible structure encouraging informal meetings and knowledge sharing. The dynamic atmosphere is intensified by the complex and innovative exterior expression.

A unique façade design was developed in order to set new standards within sustainable solutions. The three dimensional façade in fiberglass and travertine works as a screen against the sun while still providing a view to the water. In this way, the architecture itself is actually the main contributor to the energy savings of the building.

Shape which saves energy

From the start, the objective was to design a building that didn’t just live up to the existing energy saving requirements, but that set new standards in surpassing these environmental regulations in the building code.

In order to shield against overheating, it was necessary to design the building in such a way that it is closed to the south and opened to the north. Because of the three dimensional relief, the facade works as a screen against the sun, thus allowing a pleasant office temperature. This is done while still providing a view to the water with each office having its own individually framed ‘bow’.

In other words, it is the architecture itself that has contributed most to energy savings in this building; the building’s orienta- tion and the facade’s three-dimensional self shielding design.

New Materials

With its unique design, the facade is also unique in its material composition. To adapt to the special geometry, it was natural to design using new and innovative building materials and methods.

If the same facade was to be built using traditional construction methods (ie. steel frames), it would be a challenge to build each element separately and therefore difficult to keep uniformity. By contrast, by taking the decision to build completely out of fibre- glass, it becomes possible to mass produce with much fewer discrepancies amongst the various building elements.

- In our research, we found several relevant references to ships and windmills – but no building projects with self-supporting and insulating fibreglass elements, says Bo Boje Larsen, Architect and Partner in 3XN.

The production method using fibreglass has been well known in many capacities, which allows for accurate projections and the know-how to actually design with it. The ‘innovation’ has been integrating fibreglass into building design.

The end result is a facade design which consists of two layers of fibreglass composite, with a highly insulated core of foam; upon which is placed an outer layer of travertine.

Optimal Design

In order to keep within the budget, it was necessary to design a facade with as many repetitions as possible without losing the unique expression of the building. Making the floor slab design zig-zag shaped allows for a very rational and efficient way of attaching the facade. In addition, by making optimal use of the moulds, it is made possible to realize the complex geometry without compromising the original architectural vision.

- Two years of research and development doesn’t really feel like hard work when we begin to see the results take form. The hardest challenges have actually been the most fun. In fact, it is these challenges that enrich the experience of an architect, says Olaf Kunert, an Architect on the project at 3XN.

critique's attitude really puzzles me.. as it is rather defeatist. once you draw a hard line between architecture and construction, as artificial as that differentiation might be, you disenfranchise yourself from the global building culture.

and seriously... there's more to "delight" than just the creation of architectural space. I think your definition of it is too limited. is there i.e. no delight in getting something done that fulfills its purpose - on time and on a (minimal) budget? I'd see "delight" in that, too.

At some point these very interesting building skins become terribly inefficient, in terms of what you enclose versus how much you end up paying for it. Compared to the much more boring 'developer-driven' offices in the USA, these buildings begin to look like the silver-plated luxury-cars custom made for oil sheiks. I understand it looks cool, and people ought to be able to spend their money as they see fit. I'm just pointing out how some things we perceive as being so cool are really so wasteful.

There is a difference between 'construction' and 'architecture'. Architecture has elements of design for 'delight' in the built form, in the aesthetic, the materiality and the space that is created. Construction is all about achieving the cheapest and fastest possible built form to satisfy the function, without overly compromising the quality. There is no 'delight' in the built form, there is no 'architecture.

Your comment puzzles me on an architecture website.

@Hampton.... for real, dude? Why oh why would you take the time to read AND post on a website like this with an attitude like that?

I like the windows though they do look dizzy and I don't quite understand how the facade actually works environmentally - I get what you tried to achieve, but I don't understand how you achieved it..

Otherwise - I love Copenhagen, Architecture of the North is ABSOLUTELY FASCINATING :)

I wouldn't want to have those slanted windows in my office... think I'd get vertigo. Otherwise, a really interesting project - nice facade, and great materials.

simple and very impressive! Nice work
