What makes Brent Architects Special?

Brent’s architecture is both traditional and contemporary in style and seeks to capture the local history as well as the progressive nature of the area. The iconic Wembley stadium is one of the modern wonders of architectural design, but the streets of Brent are filled with Victorian and Edwardian houses, giving Brent the unique atmosphere it retains today. These Victorian houses, with their boundaries and elaborate fronts, provide a vibrant view of London in the late nineteenth and mid-twentieth centuries.

In the modern world, changes and innovations have come in handy to design new structures that beautify the area with modern housing and mixed-use buildings to accommodate the increasing population, diverse communities of Brent. Property owners are also embracing the possibilities of loft conversions and extensions to combine the best of contemporary functionality with traditional aesthetics. Brent can be considered the town where old and new harmoniously intersect, and architecture plays a crucial role, where it becomes possible to combine both historical features and modern design.

Victorian terraces and 1930s semis dominate NW10 — ideal for rear and loft projects.
Conservation areas restrict PD on some streets — pre-application advice is recommended.
Strong local demand means well-designed extensions consistently add lasting property value.
Brent Council works to a clear 8-week householder planning decision timeline.

Usually not, if you’re doing a single-storey rear extension — that falls under Permitted Development in most cases. But if you’re in a conservation area, going double-storey, or your property’s lost its Permitted Development rights through an Article 4 Direction, you’ll need full planning permission from Brent Council. The good news is you don’t have to guess: we check your address for free before any design work starts, so you know exactly which route you’re on.

Brent properties suit single-storey rear extensions, double-storey additions, side returns, loft conversions, and wraparound extensions. The dominant stock across NW10, HA9 is Victorian terraces and 1930s semis, which responds well to these approaches. We advise on the right option for your home and budget free of charge.

In Brent conservation areas, most external alterations need full planning from London Borough of Brent, and designs must respect the area’s character. Permitted Development is restricted. We check whether your street is designated and prepare a sympathetic scheme free of initial charge.

London Borough of Brent targets 8 weeks for householder applications from validation. Conservation area or more complex cases can take up to 13 weeks. Once granted, permission stays valid for 3 years. We track every application closely and respond to any council queries immediately on your behalf.

Yes, in most cases — you’ll just need full planning permission rather than relying on Permitted Development, and the design needs to respect the character of the area (materials, roofline, how it sits on the street). It’s more paperwork, not a dead end. We check conservation area status as part of our free initial assessment and shape the design around what the council is actually likely to approve.

It depends on the size and complexity of the project, but you’re never left guessing — we give you a clear cost estimate during a free feasibility check, before you agree to anything. That fee typically covers the design, the planning submission, and technical drawings, and because we’ve got a structural engineer in-house, you’re not paying two firms to coordinate with each other.

Mostly, that we know Brent specifically — not just planning law in general. We’ve done 37+ projects across NW10, HA9, and NW2, we’re RIBA-chartered and ARB-registered, we’ve got an in-house structural engineer, and we’re sitting at a 98% planning approval rate. Before any fee is agreed, you get a free feasibility check covering the planning route, any site constraints, and a realistic timeline — so there’s no pressure to commit before you know what you’re actually dealing with.
