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.
Halifax is a market town in the Metropolitan Borough of Calderdale, West Yorkshire, with a strong heritage in the wool and textile trade. The Piece Hall, a magnificent 18th-century cloth hall now transformed into a cultural venue with shops and events, is its centrepiece. The town is also home to Eureka! The National Children's Museum and sits close to the beautiful Pennine moorland.
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.
