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.

Perth is a city in central Scotland on the River Tay, often referred to as the Fair City. It was the capital of Scotland during the medieval period. Scone Palace, near Perth, is where Scottish kings were traditionally crowned on the Stone of Destiny. The city is a gateway to the Scottish Highlands and the Perthshire countryside, offering some of the most spectacular scenery in Scotland.

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.
