Planning & building regulations
Compliance handled before you build
Every loft conversion needs building regulations approval. Some also need planning permission. We clarify what applies to your property and manage the process.
At your consultation, we explain whether your loft conversion falls within permitted development or requires a planning application. We assess factors such as dormer volume, roof height, conservation area status, and Article 4 directions that may affect your property.
For building regulations, we prepare structural drawings, insulation specifications, fire escape routes, and staircase designs — submitting a full package to building control before work starts. Inspections are booked at each key stage, and final approval is obtained before handover. You focus on the exciting parts of your loft conversion; we handle the paperwork.
