Our work in Staines-upon-Thames
With 86 projects completed across TW18 and TW19, Staines-upon-Thames is one of our most active areas. Our work here covers everything from single storey rear extensions and wrap-around extensions to loft conversions, bungalow-to-house conversions and full first floor additions.
Staines has a large and varied housing stock. The majority of the homes we work on are post-war semi-detached houses and bungalows. The area has a particularly high proportion of 1950s and 1960s bungalows — a property type we have extensive experience extending and converting in Staines, often transforming them into full two-storey homes. There are also a good number of detached properties and terraced homes across the TW18 postcode.
Meadway Close, Staines TW18
A 1970s semi-detached property where the client wanted to make better use of the side and rear of the house. We designed a single storey wrap-around extension creating a generous open-plan kitchen and dining space, a utility room and a garage store. We also carried out a hip-to-gable loft conversion with a rear dormer under permitted development rights. The combination of the wrap-around extension and the loft conversion significantly increased the usable space in the home without requiring a full planning application for the upper works.
Riverside Close, Staines
A project we are particularly proud of on Riverside Close involved a 1950s bungalow that the client wanted to transform into a full two-storey family home. We designed a ground floor rear extension to expand the footprint, then added a complete first floor over both the original bungalow and the new extended area. This type of bungalow-to-house conversion requires careful design work to ensure the first floor sits proportionately on the original structure and satisfies Spelthorne’s requirements around scale and character. The result was a substantially larger home on the same plot — without the client needing to move.

Planning permission for extensions in Staines
Extensions in Staines fall under Spelthorne Borough Council. Spelthorne has historically been one of the more measured and straightforward councils we work with, but requirements have changed significantly in 2025 and 2026. Applications now require a Climate Change Checklist, Sustainable Drainage information and a Design Code Checklist as a minimum — and submissions without these will be returned as invalid before registration.
Our in-house planning team manages all of this on your behalf. For a full breakdown of what Spelthorne now requires and what it means for your project.
Many extensions in Staines can still proceed under permitted development without a formal application. Our team will confirm your permitted development position as part of the free initial consultation.
