Builders in Slough,
Berkshire
AA Contractor are local builders based in Farnham Common, right on the edge of Slough. We work across the whole SL postcode area — from the terraced streets of Chalvey and Salt Hill to the newer builds in Langley and Cippenham.
“We know Slough well. We know the housing stock, the roads, the planning rules at Slough Borough Council, and the kind of work homeowners here need most.”
Why Slough Homeowners Are Improving Rather Than Moving
Property in Slough has changed significantly over the last decade. The arrival of the Elizabeth Line changed everything. Direct rail connections to Paddington, Bond Street, and Liverpool Street in under 30 minutes made Slough one of the most accessible commuter towns in the South East.
The result is that more people are choosing to extend and improve their existing homes rather than face the cost and disruption of moving. Stamp duty alone on a larger home in the SL1 or SL2 area can run to tens of thousands of pounds. A well-built rear extension or loft conversion often costs less and adds more usable space than an entire house move.
Slough also has a strong rental market. With Heathrow Airport less than four miles from the town centre, landlords across Langley, Colnbrook, and the areas bordering Hayes regularly invest in refurbishments and extensions to increase rental value. We work with both groups — homeowners improving their family homes and investors upgrading their properties.

Every property is different. A 1930s semi in Burnham has different challenges from a post-war terrace on Farnham Road or a modern detached on a Langley new-build estate. We cover all of it.
House Extensions in Slough
Running out of space at home is one of the most common reasons people contact us. A growing family, a need for a home office, or simply a kitchen that was never big enough — a house extension solves the problem without the cost of moving. We build rear, side, double-storey, and wrap-around extensions across all parts of Slough.
- Single-storey rear extension: Under permitted development, most attached houses can extend up to 3m (or 6m via prior approval). We handle all paperwork with Slough Borough Council on your behalf.
- Double-storey extension: When you need more space upstairs as well as down — ground and first floors share the same foundations and roof for far less than two separate projects.
- Side return extension: Many Victorian and Edwardian terraces near Slough High Street and Salt Hill have a narrow passage that can be transformed into kitchen width.
- Wrap-around extension: A rear and side extension combined into one L-shaped structure, dramatically expanding kitchen and living space.
Loft Conversions in Slough
A loft conversion is one of the most efficient ways to add a bedroom or usable room to your home. You are using space that already exists above the ceiling. In most cases the work falls under permitted development — no planning application needed. The type of conversion depends on your roof structure.
Slough has a significant number of properties with hipped roofs — common in the 1930s and 1950s semi-detached houses throughout Burnham, Cippenham, and Britwell. These benefit most from a hip-to-gable conversion.
- Dormer loft conversion: The most popular option. Extends from the rear slope, creating full headroom and a vertical rear wall. Most dormers in Slough complete in 6–8 weeks.
- Velux loft conversion: Simplest and least expensive. Velux windows installed into the existing slope — no structural alteration to the roof shape.
- Hip-to-gable conversion: Ideal for the hipped-roof semis throughout Langley and Cippenham. Dramatically increases floor space.
- Mansard conversion: Creates a near-full additional storey at roof level. Usually requires planning permission.
Home Renovations in Slough
Older properties across Slough often need more than cosmetic work. Many terraced and semi-detached homes built between the wars still have original layouts that no longer suit how people live today — narrow hallways, small kitchens at the back, disconnected rooms. These are fixable problems.
We carry out full and partial home renovations covering everything from structural reconfiguration and replastering to new flooring, kitchen and bathroom fitting, decorating, and electrics. We coordinate all trades, so you deal with one team rather than juggling multiple contractors.
- Full house refurbishments for homeowners who have bought a run-down property
- Landlord refurbishments between tenancies — kitchens, bathrooms, and decorating
- Layout changes: removing non-structural walls to create open-plan living
- Damp remediation and replastering in older properties
- Complete kitchen and bathroom renovations
More Services Across Slough
From garden offices to structural steelwork, we manage every aspect of your building project under one roof.

Building a new home on a plot in Slough, Burnham, or Farnham Common? We manage the build programme, coordinate all trades, and maintain communication with building control throughout. We also carry out new-build annexes and self-contained units.

Frequently Asked Questions — Building Work in Slough
Common questions from homeowners and landlords across the SL postcode area.
-
Not always. Many single-storey rear extensions fall under permitted development rights and do not require a formal planning application to Slough Borough Council. The main limits under permitted development are 3 metres for attached houses and 4 metres for detached properties, measured from the original rear wall. Larger extensions are possible through the prior approval process. Double-storey extensions, side extensions on corner plots, and any build in a conservation area will typically need full planning permission. We advise you on this at the site visit stage.
-
A single-storey rear extension typically takes 10 to 16 weeks from breaking ground to completion, depending on size and specification. Double-storey extensions generally take 16 to 24 weeks. Loft conversions run from around 6 to 10 weeks. These timelines assume no significant planning delays, which is why getting applications submitted promptly matters.
-
The Party Wall Act 1996 applies when building work is carried out on or near a shared wall, boundary, or near a neighbour’s foundations. In Slough’s densely packed terraced streets — such as those off Farnham Road, Ledgers Road, and the roads around Chalvey — party wall issues come up regularly. If your project triggers the Act, your neighbour must be formally notified before work begins. We can advise whether this applies to your project and point you toward a party wall surveyor if needed.
-
Yes. All loft conversions require building regulations approval regardless of whether planning permission is needed. We submit the relevant applications to Slough Borough Council’s building control department and arrange for the required inspections at each stage of the build. You receive the completion certificate when the work passes final inspection.
-
The most visible signs are patches or tide marks on lower sections of internal walls, often between floor level and around a metre high. You may also see white salt deposits on exterior brickwork, plaster that is soft, blown, or peeling near the skirting boards, and a persistent damp smell in ground-floor rooms. Some of these symptoms are caused by other issues — condensation, penetrating damp through poor pointing, or a bridged DPC — rather than true rising damp. We diagnose properly before recommending treatment.
-
Yes. We work regularly with landlords across Slough’s SL1, SL2, and SL3 postcode areas, carrying out refurbishments, maintenance work, and improvements between tenancies and with tenants in situ where the work allows. We aim to cause as little disruption as possible and can work around tenant schedules where required.
-
We cover all parts of Slough and regularly work in Windsor, Maidenhead, Burnham, Taplow, Iver, Gerrards Cross, Beaconsfield, Uxbridge, Hayes, and surrounding Berkshire and Buckinghamshire areas. Our office in Farnham Common puts us at the centre of most of our regular working area.

Yes. We visit your property, assess what is needed, and provide a written, itemised quote at no cost and with no obligation. We do not charge for site visits and we do not follow up aggressively if you decide not to proceed.
