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.

Stockport is a large town in Greater Manchester, situated at the confluence of the rivers Goyt and Tame which form the River Mersey. The town is known for its Victorian Covered Market, the Stockport Viaduct, and its hat-making heritage celebrated at the Hat Works Museum. Stockport County FC is the local football club. The town has excellent rail links to Manchester Piccadilly and is a popular commuter base.

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.
