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.
Near Bradford lies the Yorkshire town of Keighley. A market town, it lies near the rivers of Worth and Aire and is close to the Leeds and Liverpool Canal. It was a major centre for the wool and cotton industries during the 18th and 19th centuries. The town has historical landmarks including Cliffe Castle Museum, the Keighley and Worth Valley Railway — famous for its connection to The Railway Children — and East Riddlesden Hall.
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.
