House Extensions in Slough: A Complete Homeowner’s Guide
With property prices continuing to rise, many homeowners in Slough are choosing to extend their existing homes rather than move. A well-designed house extension can provide valuable extra space, improve how your home functions day to day, and significantly increase property value.
In this guide, we explain everything you need to know about house extensions in Slough, including popular extension types, planning permission, costs, timescales and how to choose the right builder for your project.
Why Homeowners in Slough Are Choosing Extensions
Slough has a wide range of property types, from older family homes to modern developments. As families grow and lifestyles change, extending an existing property often makes more sense than relocating.
Common reasons homeowners choose extensions include:
- Creating open-plan kitchen and dining spaces
- Adding extra bedrooms or bathrooms
- Improving natural light and layout
- Increasing property value without moving
A professionally built extension allows you to stay in a location you already love while adapting your home to suit your needs.
Popular Types of House Extensions in Slough
Single-Storey Extensions
Single-storey rear or side extensions are one of the most popular options. They are ideal for expanding kitchens, dining areas and living spaces and often fall under permitted development.
Double-Storey Extensions
Double-storey extensions are suitable for homes needing significant extra space. They allow you to add both living areas downstairs and bedrooms or bathrooms upstairs.
Side Return & Wraparound Extensions
Side return and wraparound extensions are common on properties with unused side space. These designs maximise ground floor space and are ideal for creating large open-plan layouts.
Do You Need Planning Permission for an Extension?
Some house extensions in Slough fall under permitted development, meaning planning permission may not be required. However, this depends on factors such as:
- Extension size and height
- Property type
- Location (including conservation areas)
Even when planning permission isn’t required, all extensions must comply with building regulations. A professional builder can advise you on both planning and compliance from the outset.
How Much Does a House Extension Cost in Slough?
The cost of a house extension varies depending on size, complexity, materials and finishes. As a rough guide:
- Single-storey extensions typically cost less than double-storey builds
- Structural alterations and steelwork increase costs
- Kitchens, bathrooms and bespoke finishes add to the overall budget
It’s important to work with a builder who provides clear, itemised quotes, so you understand exactly what’s included.
How Long Does a House Extension Take?
While every project is different, most house extensions follow a similar timeline:
- Planning and design
- Groundworks and foundations
- Structural build and roofing
- Windows, doors and insulation
- Internal finishes and sign-off
A typical single-storey extension may take 8–12 weeks, while larger or more complex projects can take longer. Clear scheduling and good project management are key to keeping things on track.
Choosing the Right Builder in Slough
Selecting the right builder is one of the most important decisions you’ll make. Look for a builder who:
- Has experience with extensions in Slough
- Provides clear, written quotes
- Offers full project management
- Communicates clearly throughout the build
A local builder with knowledge of Slough properties and regulations can help avoid delays and unexpected issues.
