Will I require building regulation approval?

All loft conversions will have to meet the latest building regulations and be approved by the local Building Control Officer. This is because the loft is being turned into ‘habitable space’ which must as a result have appropriate levels of health and safety. With this in mind, the subsequent areas are predominantly important:

Loft structure?

Structural strength of your loft must be sufficient to support another habitable level. This will usually require at least two new RSJs (rolled steel joists) to be inserted into the walls of the top floor. In addition, the existing joists in the roof void are likely to measure 102mm x 51mm (4in x 2in) which will not support a new floor. New fire-resistant joists measuring at least 153mm x 51mm (6in x 2in) will have to be installed. we include structural calculations with our building control applications.

Building control and most construction work  go hand-in-hand. as a result when scouting for quotes builders will ask "have you got construction drawings" our building control drawings (construction drawings) are detailed scaled representations of what is to be constructed on site. we include with our standard service.

1. detailed drawings

2. specification

3. structural calculations

4. timber and steel layout drawings

5. application submission

6. council amendments if required
