Timber Windows Richmond upon Thames

Seventy-plus conservation areas. That’s not a typo. Richmond upon Thames has more protected zones than almost any borough in London. What that means practically: if you’re replacing windows here, there’s a better-than-even chance you need timber. Not as a preference. As a planning requirement.

Our windows are manufactured to your exact measurements — choose engineered pine, meranti, or oak. Each frame arrives factory-finished and ready to fit. We deliver across the borough; installation is your joiner’s job.

The architecture here spans three distinct eras, all heavily protected. our Georgian sash windows guide terraces overlooking Richmond Green. Victorian villas in East Sheen and Barnes. Edwardian avenues in Kew and St Margarets. And Richmond Council’s conservation team doesn’t just expect timber — they expect the RIGHT timber, with the right proportions for each era.

This is where most replacement window orders go wrong. Each era has different proportions, and conservation officers here know the differences by sight.

Georgian (pre-1837) — Richmond Green, the Hill, Petersham, parts of Ham. Six-over-six or eight-over-eight sash patterns. Glazing bars at 15-18mm face width. Panes are roughly square. The overall window is taller than wide, with slender proportions. Our slim double-glazed-glazed units fit behind bars as narrow as 18mm.
Victorian (1837-1901) — East Sheen, Barnes, parts of Twickenham. The glazing pattern simplifies: two-over-two by 1870, one-over-one by 1890. Bars widen to 20-25mm. Windows become taller relative to width. Horns appear on the upper sash.
Edwardian (1901-1910) — Kew, St Margarets, Hampton. Wider windows, lower proportions (lower ceiling heights). Margin-light patterns common: small panes surrounding a larger central pane in the top sash. Casement windows also appear on upper floors.
When ordering: specify your era. It affects bar width, sash proportions, horn detail, and glazing pattern — all things Richmond’s conservation officers check.

Richmond’s larger Victorian and Edwardian houses often have a feature window on the half-landing of the staircase. These are typically oversized — sometimes arched, sometimes with decorative coloured glass in the upper panes. They’re often the most visible window from the street.

Homeowners order matching sash windows for the main rooms and then realise the staircase window is a completely different specification: different size, different shape, sometimes a different opening mechanism. It needs separate measurement and its own quote.

If your Richmond property has a staircase feature window, measure it at the same time as everything else and send it to us as a separate line item. We’ll quote it alongside your standard windows. And if it’s arched, note the radius — we can manufacture curved-head frames, but we need the exact geometry.

While you’re checking: look for fanlights above the front door, side lights alongside entrance doors, and any small fixed windows in bathrooms or WCs. These add up. Better to quote everything at once than discover you’ve missed three windows after the order is placed.

Sash — the standard for Richmond period properties. Spring-balanced or weights. From ££449+VAT+VAT.
Flush casement — for newer riverside developments and rear extensions.
Georgian style — multi-pane with authentic bar configurations. BS 644. Single glazing for listed buildings.

Richmond orders tend toward the higher end — larger windows, more complex specifications, Georgian bar requirements. That reflects the properties, not inflated pricing. Energy efficiency details here.

Wrong glazing bar width for the era. Georgian: 15-18mm. Victorian: 20-25mm. Richmond conservation officers measure these.
Wrong glass type on a listed building. If consent says “single glazing to match original,” that means single. Not slim double. Not vacuum. Order AFTER consent is confirmed.
Forgetting the staircase window. Covered above — but it’s so common it bears repeating. Measure ALL windows including feature windows, fanlights, and side lights.
Confusing the Kew World Heritage buffer zone with a standard conservation area. The Kew Gardens UNESCO World Heritage Site has a buffer zone extending beyond normal conservation boundaries. Development within this zone can involve Historic England as well as the borough council. Check whether your property falls within it.

How many conservation areas does Richmond upon Thames have?

Over 70 — one of the highest concentrations in London. Areas include Richmond Green, Petersham, Kew, Barnes, Twickenham riverside, and Hampton Court surroundings. Check richmond.gov.uk for your specific property.

What glazing bar width do Georgian windows need in Richmond?

Georgian originals typically have 15-18mm face width bars. Victorian bars are wider at 20-25mm. Richmond conservation officers check these measurements — specify the correct width for your property’s era.

What’s the investment for sash windows on a Richmond period property?

A typical Victorian villa with 8-12 sash windows costs roughly £6,000-£10,000+VAT. Georgian properties with 10-14 windows run higher at £8,000-£14,000+VAT due to multi-pane bar requirements.

Does the Kew World Heritage buffer zone affect window replacement?

It can — the buffer zone extends beyond standard conservation area boundaries and may involve Historic England in development decisions. Check whether your property falls within it on Richmond Council’s planning portal.

Can you make arched or curved-head windows?

Yes — we manufacture curved-head frames for staircase and feature windows. Send us the exact radius measurement alongside your standard window specifications.
