Construction of a Netto market by conversion and extension of a residential and commercial building in Hamm, Heessener Straße 79

Existing building in solid construction with load-bearing walls and reinforced concrete supports with sub-beams in in-situ concrete.

With the exception of one area for a solar studio, the ground floor was completely gutted. All load-bearing walls were replaced by fire-retarded steel structures. The expansion area was designed in a steel skeleton construction. The entire flat roof area in the old building area was energetically refurbished, with a new mineral wool insulation as a countertop and new foil cover. The available green roof had to be removed for static reasons. The new exterior walls are made of high-insulation brickwork, with exterior plaster. Areas are covered with large-format ventilated Trespa facade panels. The reinforced concrete floor slab was insulated from the bottom in the expansion area, the existing concrete floor covering was completely removed and replaced by a tile floor in a shaking process.
The new facade glazing in the entrance area and for the baking shop have been designed as a heat-insulated aluminum post-beam structure with high-insulation sun protection glass.

The original small-scale shop use was no longer market-oriented. The small-scale division was replaced by a single large area. The redesign of the entrance area with the attached baking shop is geared exclusively to the newly designed customer car park.
