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.

Rochdale is a town in Greater Manchester, historically significant as the birthplace of the Co-operative movement — the Rochdale Pioneers opened the first successful co-operative store in 1844. Rochdale Town Hall is considered one of the finest Victorian Gothic buildings in England. The town has close access to the Pennine moorland and the village of Littleborough sits at the foot of the Pennines on the edge of the borough.

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.
