Heritage consultant Windsor
Heritage consultants in Windsor.
Listed building consent, heritage statements and conservation advice across Windsor, Eton and Maidenhead, from Georgian townhouses and riverside villas around the castle to Thames villages and market towns across Berkshire.
We respond within one working day leading to a no obligation outline approach.
The Royal Borough of Windsor and Maidenhead has 27 designated conservation areas, from Windsor Town Centre and Eton to Bray, Cookham and Hurley. We work in every one.
Windsor’s historic core sits beneath the Grade I listed castle, with the Guildhall on the High Street, Georgian and Victorian townhouses along Thames Street and Park Street, and the long Victorian shopping streets around Peascod Street. Across the river, Eton High Street leads to Eton College. Around them are Thames-side villas, brick and timber framed cottages, churches and riverside boathouses. Our work runs from a single listed house to the reuse of banks, shops and larger institutional buildings.
Heritage consultancy in Windsor
What we do in Windsor.
1.
Listed Building Consent
The Royal Borough of Windsor and Maidenhead decides listed building consent from Windsor and Eton out to Maidenhead, Cookham and the villages of the south of the borough. At 25 High Street, opposite the Guildhall, we took a Grade II listed former bank from pre-application stage to consent. We prepare the drawings, schedules and justification the conservation officer needs to decide quickly.
2.
Heritage Statements
Works in Inner Windsor, Windsor Town Centre or Eton conservation areas, or within the setting of Windsor Castle, need a heritage statement that deals with the NPPF and the Royal Borough’s own policies. Views to and from the castle carry real weight here. We assess significance and impact against each conservation area appraisal, so the statement answers the questions the council will ask.
3.
Georgian Townhouses and Riverside Villas
Much of the listed stock in Windsor, Eton and Maidenhead is brick fronted Georgian and Regency housing, with Victorian villas along the Thames at Maidenhead Riverside, Bray and Datchet. Sash windows, panelled interiors, staircases and plan form usually hold the significance. We record what survives and advise on how kitchens, bathrooms, extensions and new services can be fitted without loss of historic fabric.
4.
Conservation Management Plans
Schools, churches, estates and institutions hold some of the most important buildings in the Thames Valley, from Eton and the riverside churches to country houses at Bisham and Hurley. A Conservation Management Plan gives these owners an agreed understanding of significance to guide repairs, funding bids and future change. We produce plans that are clear and practical.
5.
Solar for Listed Buildings
Windsor’s roofscape of clay tile and slate is seen from the castle, the Long Walk and the river, so siting decides most solar cases here. At 25 High Street we secured consent for panels on a modern rear roof slope close to the ridge. Around Marlow and Henley the Chilterns National Landscape adds weight to views. We look for rear slopes, flat roofs and outbuildings, and set out the public benefit of the clean energy generated under the NPPF.
We hold an active caseload across Windsor and the wider Thames Valley and Berkshire area. If your area is not listed, we still work there.
That includes Windsor, Eton, Old Windsor and Datchet, Maidenhead, Bray and Cookham, Slough, Staines and Spelthorne, Reading, Wokingham, Newbury and West Berkshire, Marlow and Henley-on-Thames. We also carry out pre-works recording of listed buildings to CIFA standards across all of them.
Featured Windsor project
A Grade II listed former bank opposite the Guildhall, back in use.
25 High Street, Windsor
A Grade II listed former bank in the Windsor Town Centre Conservation Area, divided into two commercial premises with solar panels on the rear roof slope.
Heritage Unlimited prepared a Heritage Statement with a room by room gazetteer, and advised on targeted opening up that answered the conservation officer’s holding objection and revealed historic timber framed partitions, which the scheme then kept. The Royal Borough granted listed building consent in April 2025, finding no harm to the listed building, its setting or the conservation area.
