Uxbridge
AVA Home Design provides architectural design and planning services across Uxbridge, including house extensions, loft conversions, garage conversions, outbuildings, HMO conversions and planning applications. As Uxbridge sits within the London Borough of Hillingdon, most projects need planning permission or prior approval, and our team manages the full process for you.
Uxbridge is the administrative centre of the London Borough of Hillingdon, with the council's Civic Centre based in the town. Whether you are extending a family home, converting a loft or garage, or planning a new HMO, AVA Home Design produces the drawings and planning submissions your project needs and liaises with Hillingdon's planning department on your behalf.
Led by Architectural Technologist Sevda Kucuk, with 17 years of experience and a 90% planning approval rate across 300-plus projects, AVA works with the London Borough of Hillingdon and understands how local designations affect what you can build. We will assess your site early so you know whether your scheme falls under permitted development or requires a full planning application.
Local planning notes
- Hillingdon is the local planning authority for Uxbridge, with its Civic Centre located in the town centre.
- Since December 2025 a borough-wide Article 4 Direction means converting a home (Use Class C3) into a small HMO for three to six unrelated occupants (Use Class C4) requires planning permission anywhere in Hillingdon, including Uxbridge. This previously applied only in the Brunel and Uxbridge South wards.
- Uxbridge has several conservation areas, including Old Uxbridge/Windsor Street and Rockingham Bridge, where permitted development rights are restricted and extensions, alterations or demolition are more likely to need planning permission.
- The north of the borough lies within the Metropolitan Green Belt, where development is tightly controlled, so it is worth checking whether your property is affected before designing.
- Always check whether an Article 4 direction, conservation area or other local designation applies to your specific street before assuming a project is permitted development.

Frequently asked questions
- Do I need planning permission in Uxbridge?
- It depends on your project. Many extensions, loft conversions and outbuildings can fall under permitted development, but Uxbridge sits within the London Borough of Hillingdon, and conservation areas, the Metropolitan Green Belt and Article 4 Directions can remove those rights. AVA Home Design assesses your site first and advises whether you need a full application or prior approval.
- Can I convert a house into an HMO in Uxbridge without planning permission?
- No. Since December 2025 a borough-wide Article 4 Direction in Hillingdon means converting a dwelling (Class C3) into a small HMO for three to six unrelated people (Class C4) requires planning permission everywhere in the borough, including Uxbridge. AVA Home Design can prepare and submit the application and supporting drawings for you.
- Does AVA Home Design work with Hillingdon Council?
- Yes. AVA Home Design works with the London Borough of Hillingdon, the local planning authority for Uxbridge. We prepare planning drawings, manage submissions and respond to planning officers throughout, drawing on Architectural Technologist Sevda Kucuk's 17 years of experience and 90% planning approval rate to give your project the best chance of approval.
