The prefabricated cross laminated timber modules of this student dormitory in Hamburg were developed in close cooperation between the architects of Sauerbruch Hutton, the client and the module manufacturer Kaufmann Bausysteme. A manageable number of design details and the restriction to two module types have made this an efficient as well as inexpensive building possible.

For the time- and cost-efficient realization of the "Woodie" dormitory in the Wilhelmsburg district of Hamburg, the client's decision was made to involve a wood module manufacturer directly after the architectural competition. Following the direct commissioning, Kaufmann Bausysteme, together with the architects and structural engineers at Merz Kley, set about optimizing the area of the apartments.

The definition of the performance limits was essential, which ultimately led to the module builders being responsible not only for module production but also for the directly adjacent trades: the construction of prefabricated concrete floor structures, the production and assembly of all larch wood facades and roof waterproofing. The resulting benefits include fewer and more precise interfaces as well as subcontractor workflows that are clearly tailored to the modular design, ultimately resulting in more quality, fewer defects, shorter construction time, and therefore cost-effective solutions.

All modules were prefabricated complete with interior fittings, finished bathrooms, windows and doors, stored temporarily, packed in a watertight package, delivered to Hamburg just in time, and immediately lifted to the correct position with a crane. An intermediate storage on the construction site was not provided, not least for reasons of space. A maximum of four modules could be produced per day.

The serial production of the modules on a kind of production line brought numerous advantages in terms of accelerated assembly time and a short construction time. Added to this is the fact that assembly processes in workshop conditions and on the ground are generally cheaper and faster feasible than on site. Even more important, however, is the higher quality and precision achievable thereby, without which a modular construction of this type would not have been feasible.

Efficient sound control for timber-constructed prefab modular student residence

On six floors, 100 metres in length and made of solid wood, 371 student flats are strung out in the district of Wilhelmsburg in Hamburg. This makes "UDQ" the biggest timber student residence in Europe and the tallest timber building in Hamburg.

Inspired by the stacked containers in the Port of Hamburg, “UDQ” is made up of prefabricated timber modules that are stacked on top of and next to one other. The whole construction sits on a base of reinforced concrete. Each of the 20 m2 apartments is fully furnished – with bed, bathroom, built-in wardrobe, kitchenette and folding table. Where necessary, single modules can also be combined to create larger apartments.

Effective sound insulation is essential on a project such as this. That is why Getzner was brought on board as experts by contractor Kaufmann Bausysteme GmbH.


To prevent sound transmission between the apartments, the individual modules were bedded on Sylodyn® from Getzner. Timber was chosen as a building material due to its ecological properties and the warm interior ambience it creates. The modules were pre-fitted with Sylodyn® linear supports at the factory for reliable soundproofing.

"Sound mainly propagates through the flanking of the modules. Using elastic bearings, means we have been able to almost completely eliminate sound transmission between the individual modules", explains Hendrik Reichelt, Project Manager at Getzner.

About Sauerbruch Hutton

Sauerbruch Hutton realise individual and sustainable solutions to a wide range of programmes. The enjoyment of the sensuality of space and material, as well as the mastery of up-to-date technology and the intelligent use of existing resources of every kind are the focus of our work.

Built works range from the much-noted Brandhorst Museum in Munich to the Federal Environmental Agency in Dessau, which presents a benchmark building for the sustainable design of offices. A whole series of projects for private and public clients are currently under way in Germany and Europe.

Our projects are always inspired by and tailored to the specifics of their site, their brief and their client. Since we consider architecture to be a process of dialogue we intimately involve selected experts and consultants in every stage of the design process. Sauerbruch Hutton have been awarded numerous national and international prizes.
