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 £80,000 including VAT for a 15 to 25 m² footprint, and £80,000 to £130,000 for a larger or wraparound extension of 25 to 40 m², 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.
At the 2026 benchmark of £2,650 per square metre plus VAT, a 5m x 4m footprint works out at around £64,000 including VAT for the building work, before the kitchen, bespoke glazing or landscaping.
Double-Storey Extension Costs in Nuneaton (2026)
Double-storey extensions offer the best value per square metre. Typical costs range from £110,000 to £175,000 including VAT for a 40 to 60 m² double-storey addition.
Kitchen Extension Costs in Nuneaton (2026)
The building work for a 15 to 25 m² kitchen extension typically comes out between £50,000 and £80,000 including VAT. The kitchen itself is priced separately as a provisional sum, so the overall total depends on the kitchen specification you choose.
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.
