For WBS 70 fewer components, reduced type catalog and uniform design for all residential construction combines were standardized.

In a newly constructed panel work of the housing combine Neubrandenburg began on 3 July 1972, a trial run and on 7 October 1972, the production of elements of the WBS 70 From April 2, 1973 began the assembly of the first house of the WBS 70th 1973, the first WBS 70 - block ready for occupancy in Neubrandenburg. This five-storey building is a historical monument since 1984 and is located in Koszalin road 1/3/5/7 in the Oststadt Neubrandenburg.

  • Load level: 6.3 tons ( 63 kN as performed)
  • Consistent, uniform modular system with basic module: M = 100 mm and as Großrastermaß 12 M = 1.20 m, distances of the system lines nx 1.20 m, with a grid pattern: 6.00 mx 6.00 m
  • Maximum elements Dimensions Wall elements 6,00 m x 2,80 m
  • Ceiling elements 6.00 m by 3.00 m prestressed concrete, and 3.60 m by 3.00 m reinforced concrete

Functional Key Features

  • Minimizing traffic areas in building and apartment in favor of living space
  • Variability of apartment sizes and occupancy density by assembling the different functional units
  • Adjust the number of storeys and the outline of the floor plans at the functional and urban demands by vertical and horizontal combination of functional units.
