Lofts are the one part of a Wellingborough house that the valley position does not affect at all, which makes them a refreshingly straightforward conversation here.
The older housing has cut roofs, with rafters and purlins and space that can be opened up and strengthened. The purlins are the members doing the real work, and where a previous owner has cut one for a hatch or a water tank the roof has been quietly weakened. That gets found at the survey rather than when the new floor goes in.
Head height needs measuring rather than assuming, because floor build up and insulation take more out of a roof than anybody expects, and being a hundred millimetres short along the walking line is the difference between a bedroom and an expensive storage space.
The modern housing on the newer neighbourhoods is trussed, which means the structure gets reworked rather than strengthened. Routine work for us, and not the same job or the same price as a cut roof.
The permitted development volume allowance is forty cubic metres on a terrace and fifty on a semi or detached house. A dormer facing the road is not permitted development anywhere, and in the conservation areas, particularly in the villages where a designation may be protecting the setting of something significant, anything altering a visible roofline will be examined closely. Our loft conversion page goes through the structural options.
