Warwickshire Building & Construction Ltd | Extension & Loft Conversion Builders in Warwick

Warwickshire Building & Construction Ltd is a fully insured building contractor based in Warwick with over 25 years of continuous experience delivering house extensions, loft conversions, garage conversions, new builds, and property renovations across Warwick, Leamington Spa, Stratford-upon-Avon, Kenilworth, and the wider Warwickshire region. All work is completed in compliance with current building regulations, with building control sign-off and completion certificates provided on every notifiable project — the documentation that protects homeowners at the point of property sale. The team manages every stage of a project in-house, from planning permission application and structural engineering coordination through to final decoration, meaning one company carries full responsibility throughout rather than passing accountability between trades.

House Extensions Warwick & Warwickshire

Warwickshire Building & Construction designs and builds single-storey rear extensions, two-storey extensions, side extensions, wraparound extensions, and kitchen extensions across Warwick and the surrounding area. Single-storey rear extensions in Warwick typically cost between £26,000 and £44,000 depending on size, specification, and ground conditions — Warwickshire Building & Construction provides a detailed, fixed-price quotation following a full site survey, with no costs added after work begins. Many single-storey extensions fall within permitted development rights and require no formal planning application; where planning permission is needed, the team manages the entire submission and liaison with Warwick District Council. Structural calculations, building regulations approval, and site inspections are all coordinated as part of the managed service.

Loft Conversions & Garage Conversions Warwick

Loft conversions are among the most cost-effective ways to add space and value to a Warwick property — a dormer, hip-to-gable, mansard, or Velux conversion typically costs between £30,000 and £60,000 and adds a usable room without reducing garden space or requiring planning permission in most cases. Garage conversions offer comparable value at lower cost, transforming an underused single or double garage into a home office, playroom, gym, or additional bedroom. Warwickshire Building & Construction carries out both project types across Warwick, Leamington Spa, Kenilworth, and Stratford-upon-Avon, with all structural work, insulation, electrical installation, plumbing, plastering, and decorating handled by the in-house team.

Period Property Renovation Warwick

Warwick’s historic housing stock — Georgian townhouses, Victorian and Edwardian terraces, and properties within the town’s conservation areas — requires a builder with specific experience of period fabric, lime mortar, traditional construction methods, and the planning sensitivities that apply to listed buildings and conservation areas. Warwickshire Building & Construction has worked extensively on period properties across Warwick and the surrounding area, delivering renovations that preserve original character while meeting current building regulations for insulation, energy efficiency, and structural integrity. Open-plan living reconfigurations, kitchen and bathroom renovations, and full house refurbishments are all undertaken with the same care for the existing building as for the new work.

New Build Construction Warwickshire

For clients building from the ground up, Warwickshire Building & Construction provides complete new build services across Warwickshire — from groundworks and foundations through to plastering, decorating, and final fit-out — working alongside architects, structural engineers, and planning authorities throughout the process.
