What's involved in a loft conversion in London?

Most loft conversions in London fall under permitted development and don't require planning permission — but this depends on the type, the size, and your property's location. A structural survey comes first: your builder will check roof pitch, head height, and joist strength to determine what's feasible. The most common types are Velux conversions (minimal structural change), dormer conversions (most popular for full head height), and hip-to-gable conversions for detached and semi-detached homes. Building regulations approval is required for all loft conversions. Post on Quote2 to find builders in London who can manage the full project from design to handover.
