- In the area of Mainzer Neustadt a housing area of Wohnbau Mainz GmbH was constructed, which is composed of 156 apartments, as well as a line of shops and an underground car park. The residential buildings have 9 separate staircases with lift shafts and are composed to form a complex of main building with inner courtyard, one individual building and the Beethovenplatz, from which the name has been derived, (recently renamed by the City of Mainz to Karoline-Stern-Platz).
- The buildings each have one underground storey and ground floor, as well as 4-6 upper storeys.
- The ground area of the plot amounts to 100 m x 90 m.
- Underground storey waterproof concrete
- Load-bearing masonry made of KS (lime sand brick) shaped bricks
- 220 prefabricated concrete parts for balconies and stairs
- 8 fair-faced concrete supports with a height of up to 9 m
- Fair-faced concrete entry halls and cantilever retaining wall
- Due to the central position in the inner city of Mainz and several building sites in the surroundings, construction site logistics had to be focussed on very carefully. The construction parts of the underground storeys and the underground car park which are in contact with the ground were sealed by means of the Quinting-Zementol method.
- A large part of the construction, especially on the upper floors, was produced by means of load-bearing walls, for which KS shaped bricks were used. A total of about 220 prefabricated parts were required for balconies and stairs. The prestigious entrance portal to the community place is lined by 8 pillars made of fair-faced concrete with a length of up to 9 m. In addition to that, two fair-faced concrete entrance areas and one fair-faced concrete cantilever retaining wall were built.

Residential building Frank on Kennedyallee Frankfurt
Building in confined spaces
Customer: FRANK Heimbau Main-Taunus GmbH, HofheimConstruction period: 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.
