If you’re thinking about extending your home in Staines-upon-Thames, one of the first questions you’ll have is how much it’s likely to cost. It’s a completely fair question, and one we’re asked on almost every initial visit. While every project is different, there are some general figures that can help give you a realistic starting point.

How Much Does a House Extension Cost in Staines-upon-Thames?

Typical Extension Costs in Staines

For most homes in Staines, a single-storey extension will typically fall somewhere in the region of:

£75,000 - £120,000+

Larger extensions, or projects that involve significant internal alterations, can exceed this depending on the level of work and finish.

Double-storey extensions tend to cost more overall, but often provide better value per square metre when adding additional space.

What Affects The Cost?

The final price of an extension depends on several factors, including the size of the extension, the complexity of the structure and the materials used.

Things like large glazing systems, roof lanterns, underfloor heating and high-end kitchens can all increase the overall cost, but they also significantly improve the finished result.

Structural work, such as removing load-bearing walls or installing steel beams, will also influence the price.

Property Types in Staines

Many properties in Staines, particularly older family homes, are well suited to extensions. Rear extensions are especially popular, allowing homeowners to create larger kitchen and living spaces that open out onto the garden.

The layout of the existing house often plays a big role in how the extension is designed, and making sure everything flows properly is key to achieving a good result.

Is It Worth Extending?

For many homeowners, extending their home is a better option than moving. It allows you to stay in an area you’re familiar with while creating the additional space you need.

A well-designed extension can also increase the value of the property, particularly when it improves the layout and usability of the home.
