House Extension Specialists Surrey

House Extensions Surrey
Sometimes a house just needs more space. Maybe the family has grown, the layout no longer works, or you simply want a kitchen that flows into the garden. Moving is expensive and disruptive, and in Surrey's property market, extending what you already have often makes far more financial sense.
Refresh Renovations Surrey manages your extension project from design and planning through to the final build, with one person responsible for the whole thing from start to finish.
Why Refresh?
Home extensions in Surrey come with their own set of challenges. The area has some of the most varied architecture in the country, from Arts and Crafts and Victorian farmhouses to mid-century modern and contemporary builds, and getting an extension right means understanding the character of the property you're working with.
Refresh specialist Kelley Malcher and her team know Surrey's housing stock well. They work with carefully selected local tradespeople, handle all planning and building regulations on your behalf, and give you a fixed price and timeline before work begins. You track everything through the Refresh customer portal as the build progresses.
No coordinating contractors yourself. No ambiguity about costs. Just a clear plan, delivered.

What will my extension cost?
Every project is different, but here are some realistic starting points:
A simple kitchen extension within the existing footprint typically runs from £10,000 to £20,000. A new master bedroom with ensuite tends to fall between £15,000 and £50,000. A laundry room inserted into an existing garage or outhouse can come in from around £5,000.
Your Refresh Consultant will work through the specifics with you and give you a detailed, accurate quote before anything gets signed off.
Do I need planning permission?
Not always. Smaller single or two-storey rear extensions and loft conversions often fall within permitted development rules, meaning no planning application is required. But the rules have enough nuance that it's worth getting expert advice rather than assuming either way.
Refresh handles all planning and building regulations requirements as part of the project. If consent is needed, we take care of it.
