The certificate covers the use of the 1DR Build Building System in all areas of South Africa for the erection of single-storey buildings for the following uses:
- G1 – Offices (single tenancy only)
- H3 – Domestic residences (semi-detached houses, row houses and related outbuildings)
- H4 – Dwelling houses (detached houses and related outbuildings).
The 165 mm thick superstructure walls of the building system are constructed of cast-in-situ concrete that encapsulates 85 mm thick modular expanded-polystyrene filler blocks with a density of 26 kg/m3. This forms reinforced concrete columns and beams between the blocks. A continuous reinforced concrete ring-beam is cast at the wall head. All other aspects of construction are conventional and utilise conventional building materials.
