Building project

A three-storey building with a partial basement and 6 residential units is being built on Langer Acker street in Selm. The building complex consists of a single structure containing the apartments and the stairwell with elevator.
The residential building is a solid construction. The utility, technical, laundry, drying, bicycle and storage rooms are located in the basement.
The building is barrier-free from the basement to the top floor, and all floors can be reached via the elevator. The residential buildings will be constructed in accordance with the building regulations valid in NRW at the time of application for planning permission, the minimum requirements of the DIN standards introduced by the state building regulations, the Energy Saving Ordinance EnEV (GEG) 2024 with the increased requirements for new buildings.

Construction and appearance

Foundation
The buildings are erected on a statically calculated reinforced concrete floor slab.

Residential floors
The load-bearing exterior, building partition and interior walls of the residential floors are made of solid masonry. The non-load-bearing interior walls of the residential storeys are double planked on both sides with plasterboard. The ceilings above the ground and upper floors are made of reinforced concrete as so-called solid concrete ceilings. All wall and ceiling dimensions are based on structural calculations. In the bathroom, WC and kitchen, the cladding of the pipes and shafts will be made of plasterboard, also as a plinth or shelf, where necessary.

Roof
The buildings will have a hipped roof. The roof pitches are made of a timber construction. The roof is covered with concrete roof tiles. The space between the roof tiles and the underlay is ventilated using counter battens in accordance with the guidelines of the roofing trade. The roof is drained via gutters and external downpipes made of untreated zinc sheet.

Note:
At joints between plasterboard cladding and plastered walls/ceilings (especially
in the roof) can lead to cracks due to the different material properties.

Facades and windows
The required thermal insulation is achieved with a thermal insulation composite system. The facade plaster will be white. The windows of the building and the patio doors are made of plastic, color: anthracite. At least one window sash in each room (except for the storage room and corridors) is fitted with a turn/tilt fitting. The locking and fittings of the windows and doors on the ground floor are burglar-resistant with mushroom heads and strike plates. The windows in the living areas are designed in accordance with sound and thermal insulation certificates.

Roller shutters
The patio doors and all windows with the exception of the skylights will be fitted with roller shutters made of plastic profiles with electric drives.

Front door
The entrance door consists of an aluminum construction. The frame element is color-matched to the windows. The door is fitted with a security lock with multi-point locking, profile cylinder, a stainless steel push handle on the outside and a plastic lever handle on the inside. A doorbell system, a recessed ceiling light with motion detector, a house number and a letterbox are installed in the entrance area.

Glazing
All windows, French doors and the front door are fitted with insulating glazing in accordance with the thermal insulation certificate.

Thermal insulation and soundproofing measures
All thermal insulation measures carried out on the building are carried out in accordance with the thermal insulation certificate prepared for the building.
Noise protection measures are implemented as required.

Interior extension

Stairs
The stairs are a steel construction with solid beech treads and a wooden handrail on one side, also in beech.

Ceiling and wall treatment
All interior masonry wall surfaces on the ground floor, second floor and stairwell area are filled to quality level Q 3 with a painter's fleece (painted white).

In the bathroom, the pre-wall area is tiled to a height of approx. 1.20 m, the area around the bath is tiled to a height of approx. 0.90 m and the shower area is tiled to room height. In the WC, the pre-wall area behind the wash hand basin is tiled to a height of approx. 1.20 m and the pre-wall area of the toilet is tiled to a height of approx. 1.50 m.

Floors
All living and ancillary rooms on the ground floor, first floor and top floor will have a floating screed. The upper floors of the bathrooms and WCs will be covered with ceramic tiles, approx. 30/60 cm in anthracite color.

Interior doors
The room doors on the residential floors in wooden frames have a white coated surface. The doors are closed using a light metal lever handle set.

Window sills
The exterior window sills are covered with stove-enameled aluminum profiles.
The color tone is matched to the exterior window color. The base (external window sill) of the
Patio door is covered with an aluminum checker plate. The low-barrier patio door is
with a channel in front.
Masonry interior parapets are fitted with window sills made of artificial stone (Micro carrara), color:
white.
In the sanitary rooms, the parapet is tiled or fitted with an interior window sill.

Painting work
The steel construction of the stairs is painted white.
All walls and ceilings on the residential floors are painted white.
