SLOUGH
House Extensions in Slough
Rear, side and single-storey extension work with structural construction and internal finishing.

House Extensions for homes in Slough
House extensions in Slough need more than the shell alone. Foundations, structure, roof design, drainage, insulation, openings, services and internal finishes all have to connect correctly with the existing house.
Planning permission, permitted development, Building Regulations, structural calculations and Party Wall matters may apply depending on the property and design. The relevant responsibilities should be confirmed before construction begins.
What we can help with
- Groundworks and foundations
- Structural walls and steelwork
- Roof and weatherproof shell
- Openings and glazing preparation
- First and second fix coordination
- Internal finishing
Planning the work properly
A clear specification helps control changes once work starts. We discuss the build sequence, access, storage, waste removal and final internal finish as part of the project scope.
Residential work in and around Slough can range from targeted repairs and room upgrades to complete roof renewals and extensions. Access, parking, neighbour boundaries and the existing condition of the property are checked before a quotation is finalised.
Every quotation is based on the actual scope. We do not advertise a fixed price that ignores property condition, access, materials or the level of finish required.

Frequently asked questions
Can I get a quotation for house extensions in Slough?
Yes. Send details and photographs first. Depending on the job, we may then arrange a site visit before issuing or confirming a quotation.
Do you handle both smaller and larger jobs?
Yes, subject to suitability and availability. Smaller repair work is discussed through our general building service while larger projects receive a more detailed scope.
Which nearby areas do you cover?
We work across London and surrounding areas, with additional projects across England and Wales by arrangement.
What affects the quotation?
The cost of house extensions in slough depends on the existing condition, access, materials, waste removal, scaffold or plant requirements, the amount of making good and the finish expected. A realistic quotation needs enough information to price those items rather than relying on a headline figure.
Where hidden defects cannot be seen before work starts, any additional work should be explained and agreed before it is added to the scope.
Before work starts
- Confirm the agreed scope and exclusions
- Confirm who is responsible for permissions or structural information
- Agree access, parking and working hours where relevant
- Choose key materials and finishes early
- Confirm how changes will be recorded and priced
