Building Contractors for Exmouth Homes

Building in Exmouth: Your Questions
How much does a house extension cost in Exmouth?
Single-storey extensions in Exmouth typically start from around £50,000–£90,000, with double-storey extensions from around £90,000. The final cost depends on size, specification and site conditions. We give you a detailed, fixed-price quote after a free site visit.
Do you manage the whole project, including trades?
Yes. We keep all main trades in-house rather than relying on subcontractors, which keeps your Exmouth project on programme and to a consistent standard. We also coordinate with architects, structural engineers and building control on your behalf.
Can you convert the loft in an Exmouth bungalow?
In many cases, yes. Bungalows in Exmouth often have good roof space for a loft conversion, and a hip-to-gable conversion can work particularly well. We assess the existing roof structure at a free site visit and advise what is possible.
Are you local to Exmouth?
We are based in Honiton, around 20 miles from Exmouth, and we work in Exmouth regularly. We are familiar with the town’s property types — from period terraces near the seafront to suburban estates further inland.
