Covering Windsor
Alongside Windsor, we also cover Slough, Egham (4 miles to the south-east) and Staines.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What is a house-to-flat conversion?
We assess the house against the council’s policies on flat sizes, parking, bins and cycle storage before any design work, then design layouts to the space standards your council uses. On site the critical work is fire separation, sound insulation between floors, separate services and meters, and protected escape routes.
- Feasibility check against local planning policy
- Fire separation and sound insulation between flats
- Kitchens, bathrooms and finishes
What is the guide price for a house-to-flat conversion in Windsor?
Typical ranges for house-to-flat conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
Priced on survey.
Planning and building rules in Windsor
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
Dividing a house into flats always needs planning permission in England.
What can change the price or programme?
- Each flat needs its own utilities and metering.
- Sound insulation between flats is tested on completion.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Your questions answered
What are the main building regulations issues?

How long does a conversion take?

Can you visit a house in Windsor to quote?
