Do You Need Planning Permission for a House Extension?
Many house extensions in Leeds fall under Permitted Development rights, meaning you may not need full planning permission. Our architects will assess your project and advise on the best route — whether that’s a householder planning application, a Certificate of Lawful Development, or permitted development. We prepare all drawings and submit applications on your behalf.

Types of House Extensions in Leeds
There are several popular types of house extension, each suited to different properties and budgets. Single-storey rear extensions are the most common, typically expanding the kitchen or living room into the rear garden. Two-storey extensions offer more living space across two floors and deliver more square footage per pound spent. Side return extensions use the narrow side passage common in Victorian and Edwardian terraced houses across Leeds, creating open-plan kitchen-dining spaces. Wrap-around extensions combine rear and side for maximum impact.
The Design and Planning Process
Our process typically takes 8–16 weeks from first meeting to planning decision. We start with a free in-home consultation and measured survey. Our architects produce detailed drawings showing the proposed design from all elevations and floor plans. Once approved, we submit your householder planning application to Leeds City Council and handle all communication throughout the 8-week determination period.
We also produce Building Regulations drawings once planning is approved, giving your contractor everything they need to quote and build.
House Extension Costs in Leeds
A typical single-storey rear extension in Leeds costs between £25,000 and £50,000 to build, depending on size and specification. Our architectural fees start from £1,500 for planning drawings, with a fixed-price guarantee so you know the full cost before we start. Two-storey extensions range from £40,000–£80,000 to build, and our fees reflect the additional complexity involved.
Planning Permission for House Extensions
Many smaller extensions may be possible under Permitted Development rights without formal planning permission. However, Leeds City Council applies Article 4 Directions in certain conservation areas that remove those rights. We always confirm your planning position upfront and advise whether an application is required before any work begins.
