How much does a house extension cost?

The cost of a house extension can vary depending on several key factors, but understanding what affects pricing can help you plan your project more effectively. On average, house extensions in the North West typically start from around £1,500-£2,000 per square metre, but the final cost depends on the type, size, and complexity of the build.

Factors that can affect the cost include:

Size and Type of Extension: A single storey extension will generally cost less than a double storey one. More complex designs, like wrap around extensions, can increase both labour and material costs.
Structural Work: Removing walls, adding steel beams, or working around existing structures can impact the cost.
Finish and Materials: The quality of finishes—flooring, windows, doors, and roofing—will influence your budget. High-spec materials or bespoke features can add to the overall cost.
Planning and Design: Architectural drawings, planning permission, and building regulations approval may carry additional fees.
Site Access and Location: Easier access to your property makes for a smoother, more cost-efficient build, while difficult terrain or limited space may require more labour or equipment.
Utilities and Services: Moving or adding plumbing, electrics, or heating systems can also affect the final price.
