Urban planning / Location

The location for the planned residential building with 56 residential units, a commercial unit and 50 underground parking spaces is located in the Berlin district of Friedrichshain.
The ensemble consists of 4 loft houses and closes the gap between the fire walls of the front building and the rear building in Kopernikusstr. 24 and 28.
Two more loft houses attached to the western gables of the rear part of the building in Grünbergerstr. 24 are going to be built
The penthouse storeys are designed with graduated setbacks.
The courtyard area on the roof of the underground garage will enhance the residential quality by means of intensive planting. A playground and common leisure areas will create an attractive ambience.

Building construction

The building will be built of solid construction. The ceilings will be built of reinforced concrete. They will be constructed as flat ceilings which rest pointwisely on the inner supporting pillars and linearly on the load bearing walls. Depending on static requirements, the load-bearing walls will either be constructed of masonry or reinforced concrete. The underground garage as well as the basement of the building will be built of waterproof concrete.
The building will be erected on a foundation slab which is also going to be made of waterproof concrete. The thickness of the base plates will be 40 to 60 cm, depending on static requirements. In the area of the reinforced concrete supports, the floor slab will be thickened in accordance with static requirements.

Exterior walls / Facade

The exterior walls will be made of load-bearing masonry/reinforced concrete and will be equipped with a thermal insulation composite system and a light-colored final coat of plaster. The appearance of the facade will be similar to the one of the loft building at Grünberger Str. 26. On the roof level, the facade will be constructed of corrugated aluminum sheeting.

Interior walls

The partition walls between the apartments will be built of solid construction (reinforced concrete, masonry) in accordance with static requirements. All non-load-bearing interior walls will be designed as light stud walls, and covered with plasterboard in accordance with noise insulation and fire protection requirements. In wet areas, moisture-resistant plasterboard will be used. All joints between the walls and the ceilings will be permanently elastically sealed against water.

Ceilings

The reinforced concrete ceilings will be constructed as filigree ceilings, most of them with flush beams.
