Loft Conversion

Loft conversions involve new floors, new insulation, fire separation and often a dormer, all within an existing roof. This category includes options for new loft floors (keeping the existing ceiling or replacing it), floor support under stud walls, warm and cold roof eaves, flush eaves, dormer cheek junctions at party walls, and party wall fire junctions at pitched and flat roofs.

Which Building Regulations apply to loft conversions? Usually Part A (structure), Part B (fire, including the escape route), Part K (stairs), Part L (insulation) and Part C (moisture). Building control will confirm what applies to your project.

Do you have dormer details? Yes. This category has dormer cheek party wall junctions, and there’s a loft conversion dormer detail pack in Detail Packs.
