Bedford Park W4 · Conservation Area
Bedford Park Windows.
Why Bedford Park is different
Bedford Park, laid out from 1875 by Jonathan Carr with architects Norman Shaw, E. W. Godwin and Maurice Adams, is widely cited as the world's first garden suburb. The Queen Anne and Tudor Revival houses share a coherent vocabulary: red brick, white-painted joinery, tile-hung gables, and small-paned timber sashes and casements. That coherence is exactly what the conservation area Appraisal protects, and what the Article 4 Direction enforces by removing your Permitted Development right to swap windows freely.
In practical terms: a change of material, frame profile, or glazing pattern on a front or street-side elevation will normally require planning permission from Ealing or Hounslow, depending which side of the boundary you are on. Whether like-for-like timber-to-timber needs consent depends on the precise scope of the Article 4 that applies to your address, which you should confirm with the council. Always confirm with the Council Planning team before placing an order.

Recommended systems
Specifications that tend to survive Ealing's heritage review. Final approval depends on your individual property, the Article 4 conditions that apply to your address, and the case officer assigned.
| System | Best for | Approval pattern |
|---|---|---|
| Period style timber sash (Accoya / hardwood) | Front elevations, listed properties | Reliable approval |
| Timber casement, small-pane | Front elevations, side bays | Reliable approval |
| uPVC Period style with run-through horns | Rear elevations only | Case-by-case, often refused on front |
| Smart Aluspace (steel-look aluminium) | Rear extensions, garden rooms | Approved as contemporary insert |
| Slim vacuum-glazed units (6.5mm) | Listed buildings keeping original frames | Approved as a sympathetic upgrade |
How we quote windows in Bedford Park
There is no price list. Every job is quoted after a free survey, because the size of each opening, the glass, the colour, access and the work around the frame all change the price.
Frequently asked
Do I need planning permission for windows in Bedford Park?
Bedford Park sits within the Bedford Park Conservation Area, which straddles the Ealing/Hounslow boundary, so your address may fall under either council. Both boroughs have an Article 4 Direction covering their part of Bedford Park (Ealing designated the area in 1969, with extensions in 1994 and 2004; Hounslow's Article 4 covers Bedford Park and Gunnersbury). An Article 4 Direction removes Permitted Development rights for specified alterations, so a planning application is normally required for changes to windows that are visible from the public realm. The precise scope differs between the Ealing and Hounslow directions and between individual properties, and we do not publish a summary of it. Confirm the scope that applies to your address with the relevant council's planning team before ordering windows.
Can I have uPVC windows in Bedford Park?
uPVC visible from the public highway is generally refused in Bedford Park because the original 1875-1900 Norman Shaw houses had timber sash and casement windows painted white, and the conservation area Appraisal protects that character. Period style uPVC with run-through sash horns is sometimes approved on rear elevations not visible from the street, but it is not a guaranteed approval. Submit a pre-application enquiry to the relevant council before committing.
What's allowed on rear extensions in Bedford Park?
Rear extensions and rear elevations not visible from the street tend to attract a more flexible response from planners. Period style uPVC sash, slim aluminium casements, and steel-look systems such as Smart Aluspace have been approved on rear elevations in W4. Front and street-side elevations are normally expected to be timber, painted white, in the original sash or casement pattern with the original glazing-bar layout, though the officer decides each case.
How much do period style sash windows cost in Bedford Park?
Request an itemised quote for your opening and specification. Listed buildings or unusually large bay windows can exceed this range.
What did original Bedford Park windows look like?
Bedford Park is widely cited as the world's first garden suburb, laid out from 1875 onwards with houses by Norman Shaw, E. W. Godwin, and others in the Queen Anne / Tudor Revival style. Original windows are predominantly timber-framed: small-paned multi-light casements, vertical sliding sashes with run-through horns, and oriels, all painted white, with a characteristic small-pane glazing pattern.
Can I get double glazing in Bedford Park?
Yes, slim double-glazed units (typically 4-8-4mm or 4-12-4mm) are the specification most often put forward for conservation-area sashes in period style timber frames where the glazing bars and proportions match the original. Sealed units between 11mm and 16mm overall fit within traditional sash boxes without altering the visible profile. Vacuum-glazed slim units (around 6.5mm overall) are an option for the tightest historical reveals.
Are the original windows in Bedford Park listed?
Bedford Park as a whole is a designated conservation area protected by an Article 4 Direction; it is not a single listed building. However, several individual properties, including some Norman Shaw houses, are individually listed Grade II. If your property is listed, Listed Building Consent is required in addition to planning permission for any window change. Check Historic England's National Heritage List for England against your address.
Who handles the Ealing Council planning application?
Apex Glazing surveys the property, prepares like-for-like elevation drawings, and supplies the technical specification needed for an Ealing Council householder planning application. The application itself is normally submitted by the homeowner or their agent through the Planning Portal. We do not act as planning agents but we can work alongside your heritage architect.
