Building in confined spaces

Customer: FRANK Heimbau Main-Taunus GmbH, Hofheim
Construction time: 21 months Year of construction: 2013–2015
New construction of a housing complex with 142 apartments. The complex consists of 9 solitary buildings with four to six floors and set-back floors. The buildings are interconnected by an underground car park with approx. 178 parking spaces. Due to the location of the housing complex in a flood zone, the underground car park had to be realised with waterproof concrete. The works for the building shell include armoured concrete and bricklaying work.


The entire complex was planned by four different architecture firms. The underground car park was realised as waterproof concrete tanking. Production of stair railings up to 5 m of length and 10 cm of width as prefabricated parts on site. Production of ceilings with a thickness of 25 cm, as semi-finished parts with completion with in-situ concrete and installation of ventilation pipes on ceilings made of semi-finished parts.

The high-rise building with hotel and exclusive apartments is located in the new European Quarter in Stuttgart, just a few minutes' walk from the main station. It comprises 24 floors, which are divided into 4 underground levels, the ground floor, 18 upper floors and finally the attic floor. The 4th underground level up to the 5th upper floor (altogether 10 floors) have a floor area of about 2,000 square meters; the remaining floors are approximately 700 square meters. Storage and technical rooms as well as a fully-automated parking garage for about 140 cars are located in the underground level. A new Steigenberger Hotel has been created from the ground floor to the 7th upper floor. From the 8th floor to the 18th floor there are high-quality condominiums and luxury apartments.

Difficult site logistics because of Milaneo construction site running parallel and the renovation of Heilbronnerstraße and Wolframstraße. The building is built on a combined pile and slab foundation. Because of the neighboring buildings, single-sided, waterproof walls had to be formed up to 12.5 m and concreted all at one time. 24.5 m high scaffolding towers were used to support the cantilevered balconies.

Atrienhäuser und Serpentine (Atrium houses and the "snake") - Residence at Moabiter Werder, Berlin

Easy living on the Spree

Customer: DEUTSCHBAU und Frankfurter Siedlungsgesellschaft

Exceptional architecture characterizes the "snake" at Moabiter Werder, which was erected over a construction period of 21 months. The "snake skin" is formed from more than 6 million clinker bricks and, on the south side, from continuous bands of light metal windows in the facade. In the atria of the four solitary buildings, the building artwork invites you into a cozy home. Its proximity to the Lehrter railway line placed high demands on the measures taken for sound insulation. Absolute punctuality and high quality were guaranteed by professional project and site managers.
