Planning Permission and Permitted Development
Many single-storey rear extensions fall under permitted development and do not require planning permission, subject to size limits. Side and double-storey extensions, and those on properties in conservation areas, generally require a full planning application. Your builder should confirm what applies to your specific property before any other decisions are made.
What to Expect During the Build
A building extension involves groundwork and foundations, structural walls and roof, windows and external doors, insulation to current standards, and internal fit-out including electrical, plumbing if required, and plastering. A well-managed project will have a clear programme of works and a lead contractor who coordinates all trades on your behalf.
Bath is a UNESCO World Heritage City in Somerset, famous for its Georgian architecture and Roman-built baths. The Roman Baths, Royal Crescent, Circus, and Pulteney Bridge are among the finest examples of Georgian architecture in the world. Bath is a major tourist destination and has a thriving independent retail and restaurant scene. Bath Rugby Club plays at the Recreation Ground in the city centre.
Building Regulations and Structural Calculations
All extensions require Building Regulations approval regardless of whether planning permission is needed. Structural calculations by an engineer will be required for any load-bearing work. Your builder should manage the Building Regulations application and arrange inspections at the required stages of construction.
