Slough
Most home extensions, loft and garage conversions in Slough fall under permitted development, but Slough Borough Council, a unitary authority in Berkshire, handles its own planning. Confirm whether your property sits in a conservation area such as Upton, and remember HMO conversions often need planning permission on policy grounds.
AVA Home Design provides architectural design and planning support across Slough, a unitary authority in Berkshire that manages its own planning decisions through Slough Borough Council. Led by Architectural Technologist Sevda Kucuk, who brings 17 years of experience and a 90% planning approval rate, the practice prepares clear, well-documented drawings and applications tailored to local policy. Whether you are extending a family home, converting a loft, or developing a rental property, we guide you from initial concept through to a decision.
Slough has a diverse and varied housing stock and one of the strongest rental and HMO markets in the wider London area, driven by its position on the Elizabeth line and its proximity to Heathrow Airport, roughly seven miles to the south-east. With direct trains reaching London Paddington in around 22 minutes, demand for both family accommodation and shared housing is high. AVA Home Design understands how Slough Borough Council weighs proposals, including its concern about the loss of family housing to HMO use, and prepares schemes designed to address those local priorities.
Local planning notes
- Slough is a unitary authority in Berkshire and handles its own planning through Slough Borough Council, so applications and policy differ from neighbouring London boroughs.
- Slough has five conservation areas, including Upton Park/Upton Village, Colnbrook, St Mary's Church (Langley), Sussex Place/Clifton Road and St Bernard's School, where permitted development rights may be restricted and extra care is needed.
- Slough's only borough-wide Article 4 Direction relates to caravans and moveable structures, not HMOs; the council has not introduced an Article 4 removing permitted development rights for C3 to C4 small HMO conversions.
- Despite the absence of an HMO Article 4 Direction, planning permission is often required for HMOs on policy grounds, and the council's spatial strategy actively seeks to avoid the net loss of family housing.
- The Elizabeth line and proximity to Heathrow give Slough strong transport links and a strong rental and HMO market, shaping demand for extensions, conversions and shared housing.

Frequently asked questions
- Do I need planning permission in Slough?
- Many home improvements such as single-storey rear extensions, loft conversions and garage conversions can fall under permitted development, meaning no full planning application is needed. However, conservation areas like Upton, larger schemes, and changes of use to HMOs frequently require permission from Slough Borough Council. AVA Home Design can review your property and advise on the right route before you commit.
- Does Slough have an Article 4 Direction for HMOs?
- No. Slough Borough Council has not introduced an Article 4 Direction removing permitted development rights for converting a C3 dwellinghouse to a C4 small HMO; the borough’s only Article 4 relates to caravans and moveable structures. Even so, planning permission is frequently required for HMOs on policy grounds, as the council aims to prevent the loss of family housing, so it is best to check before proceeding.
- Can you help convert a house into an HMO in Slough?
- Yes. With Slough's strong rental market and proximity to Heathrow and the Elizabeth line, HMO conversions are in high demand. AVA Home Design prepares the drawings and planning applications needed and addresses Slough Borough Council's concerns around room sizes, family housing loss and amenity, giving your scheme the best chance of approval. We work directly with the council throughout the process.
