How much does a home extension cost in Farnham?

As a 2025 guide, most homeowners in Farnham pay somewhere between £23,000–£80,500 for a home extension. South East costs typically run above the UK average — Surrey labour and materials are a real factor. What you pay depends mainly on single vs double storey and floor area and foundations and structural work, plus planning, glazing and finish quality. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.

Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.

  • Match your materials. Choose brick and finishes that harmonise with your existing home.

Why a home extension makes sense in Farnham

Across Surrey, a thoughtfully designed home extension adds comfort day to day and appeal when it’s time to sell. A well-built extension typically adds both significant living space and long-term property value.

Planning your home extension in Farnham

Before you start, plan properly: set a realistic budget with a 10–15% contingency, confirm exactly what’s included in each quote, and check whether any permissions or building-regulations approvals apply. A good Farnham specialist will guide you through this.

Local know-how for Farnham

Property in Farnham tends to reflect Surrey: mock-Tudor and interwar detached homes, Victorian villas and wealthy commuter housing. The style of local homes matters for a home extension — green-belt and aonb limits, plus high values, shape most projects. A local specialist who knows Farnham will factor all of this into your quote and design.
