If you’re thinking about extending your home in Nuneaton, one of the first questions you’ll ask is: how much will it cost?
It’s a reasonable question — and the honest answer is that costs vary significantly depending on the type of extension, the size, the specification, and the complexity of the build. However, we can give you a realistic guide based on what we’re building right now, in 2026, for homeowners across Nuneaton, Hinckley, and Coventry.
Single-Storey Extension Costs in Nuneaton (2026)
A single-storey rear or side extension in Nuneaton typically costs between £50,000 and £120,000 depending on size and specification.
Size — the larger the footprint, the higher the cost. A modest 4m x 4m extension sits at the lower end; a large 6m x 8m open-plan kitchen-diner moves significantly higher.
Specification — a basic plastered finish with standard glazing costs less than a fully specified extension with bifold doors, roof lanterns, underfloor heating, and premium materials.
A well-specified single-storey extension in Nuneaton typically falls in the £70,000–£90,000 range for a 5m x 4m footprint.
Double-Storey Extension Costs in Nuneaton (2026)
Double-storey extensions offer the best value per square metre. Typical costs range from £100,000 to £200,000 for a full double-storey addition.
Kitchen Extension Costs in Nuneaton (2026)
Total costs for an extension plus new kitchen installation typically range from £80,000 to £150,000, depending on the kitchen specification.
Do I Need Planning Permission for an Extension in Nuneaton?
Many single-storey extensions in Nuneaton can be built under Permitted Development Rights — which means no formal planning application is needed. Larger extensions and double-storey additions typically require a planning application. We advise on this as part of your free consultation.
