Master Builders in Headington for Extensions, Lofts & Renovations
Delivering high-specification house extensions, bespoke loft conversions, and luxury period restorations across Headington and Oxfordshire. Backed by FMB accreditation, fixed-price contracts, and a 10-year structural warranty.
Home Extensions & Loft Conversions Across Headington
Headington combines a rich variety of residential property types—from historic Headington Quarry stone cottages and Old Headington conservation properties to classic 1930s semi-detached and detached homes around London Road, Old High Street, and Windmill Road. Many Headington homeowners, particularly medical professionals from the John Radcliffe and Churchill hospital campuses, choose to expand their living space rather than relocate. Crawford Construction excels in hip-to-gable dormer loft conversions, full-width kitchen-diner extensions, and internal structural reconfiguration. We navigate Oxford City Council Permitted Development rights and local tree preservation orders (TPOs) with precision.

Expert Builders in Headington: Planning, Conservation & Architecture
Appointing accredited Oxford building contractors and an experienced builder in Headington ensures seamless navigation of local planning controls, historic conservation bylaws, and Thames Water build-over standards.
Oxford Planning & Permitted Development
While many single-storey rear extensions in Oxford fall under Permitted Development rights (up to 6m for attached, 8m for detached properties), conservation areas and Article 4 Directions in Jericho, Headington, and Central Oxford frequently remove these rights. We prepare and submit complete planning drawings and Lawful Development Certificates directly to Oxford City Council.
Conservation Areas & Period Craftsmanship
From Victorian terraces on Magdalen and Divinity Road to substantial Edwardian villas in Summertown and North Oxford, our stonemasons and joiners specialize in authentic heritage compliance: matching Flemish brick bonds, breathable lime mortars, heritage timber sash glazing, and structural party wall agreements.
Fixed-Price Quotes & Cost Certainty
Single-storey extensions in Oxford typically range from £2,800 to £3,500/m², with bespoke loft conversions starting from £45,000. Unlike builders who quote low and inflate through variations, Crawford provides fully itemized, contractually fixed-price quotes backed by milestone staged payments.
