What is and what is Not Permissible? | Can My Roof Space Be Converted?

Question you may have for Barrisdale:

Some roof spaces are more easily converted than others. The first step is to measure the existing headroom at the centre under the ridge. It should be a minimum of 2.2m high and provide enough room to stand up beneath it. Ideally the ridge plate running along the top of the roof should be out of reach. The steeper the pitch, the greater the potential for living space. As existing joists were designed to hold up the ceiling and not to support the floor, new joists will probably need to be fitted between the original ones and then chipboard sheets screwed to the new joists. This will raise the level of the floor but will reduce the headroom.

The second step is to work out whether the roof has been built with trussed rafters or purloins (horizontal beams running along the length of the roof). Houses predating 1965 are mostly built with purloins. These are easier to convert as the roof has a reasonably steep pitch and relatively clear spaces between the supporting frameworks. Houses built after 1965 mostly have a more shallow pitch roof and trussed rafters, which result in a shallow pitch of roof, which is harder to convert.
