Construction & renovation in Windsor

Your local builder in Windsor

We build across Windsor from our base in Harefield, a short run east along the M40 and M4 that keeps our teams close and our sites well supervised. Windsor is a royal town with serious heritage: Georgian and Victorian stock, red-brick terraces near Peascod Street, interwar semis and modern infill, much of it inside one of the borough's conservation areas. Loft conversions, landscaping and house extensions are the work homeowners ask us for most, and each here is shaped by the setting of the Castle and the Great Park.

We handle the planning side with the Royal Borough of Windsor & Maidenhead directly, which matters in a town where 27 conservation areas and 956 listed buildings mean a full application is often needed for what counts as permitted development elsewhere. We know how the borough reads heritage views, conservation consent and its Strategic Flood Risk Assessment, and we detail the work to suit. From a rear extension off a Victorian terrace to a loft under a slate roof or a reworked garden behind a period frontage, we build it to last and to pass.

Local knowledge

Building in Windsor

We tailor every project to the homes, ground and planning context of Windsor — here's what that means in practice.

The homes we work on here

  • Georgian and Victorian properties with solid or early-cavity brick, sash windows, slate and clay roofs and ornate frontages, much of it listed or in a conservation area near the Castle.
  • Red-brick Victorian terraces around Peascod Street and the town centre, where rear and side-return extensions are the usual route to more space.
  • 1930s interwar semis across the wider borough, sound but dated and ready for extending, reroofing and full renovation.
  • Modern infill and later housing away from the historic core, alongside low-lying riverside plots on Thames floodplain ground.

What Windsor homeowners ask us to solve

  • Listed-building and conservation consent across the town's 27 conservation areas, particularly the streets that sit within the setting of Windsor Castle.
  • Loft conversions and extensions on period and interwar stock, designed to respect sash lines, rooflines and heritage views.
  • Thames flood-risk building on low-lying plots at Windsor, Old Windsor and Datchet, with flood-resilient detailing, raised levels and the right consents.
  • Damp on riverside and floodplain ground, and limescale from very hard water, both managed properly rather than papered over.
Why Hangard

Why Windsor homeowners choose us

What sets us apart in Windsor isn't a sales pitch — it's knowing the homes, the ground and the planning here, and building accordingly.

We build in the Castle's setting

We work daily with the heritage-view and conservation sensitivity that defines the streets around Windsor Castle, the Long Walk and the Great Park, so our designs sit right with the townscape and with the planners.

RBWM consent handled directly

We prepare and run full applications with the Royal Borough of Windsor & Maidenhead, knowing that work treated as permitted development elsewhere needs proper consent across its 27 conservation areas and 956 listed buildings.

Thames flood-risk detailing

On low-lying ground at Windsor, Old Windsor and Datchet we build to the borough's Strategic Flood Risk Assessment, with flood-resilient construction, considered levels and floodplain-aware foundations.

Period fabric done properly

We restore and extend Georgian and Victorian brick, sash windows and slate or clay roofs in matching materials, and detail riverside walls against the damp that floodplain ground brings.
