Why Choose a Garden Room Over an Extension?

Home extensions are a popular way to increase space, but they come with a hefty price tag, planning delays, building regulations scrutiny, and disruption. A garden room, by contrast, can be a faster, more flexible, and cost-effective solution.

Let’s compare.

1. Cost

  • Extension: £1,800 – £3,000 per m² (plus professional fees, VAT, and contingency).

  • Garden Room: Starting from around £600 m² , depending on size, spec and use.

A Keops garden room gives you high-quality craftsmanship, without the spiralling costs of digging foundations or moving walls.

2. Time and Disruption

  • Extension: Weeks (sometimes months) of building work inside your home.

  • Garden Room: Usually completed in just a few days on site, and in many situations 1 day on site.

Because Keops cabins are delivered using pre-manufactured wall logs, installation is quicker and less disruptive.

3. Planning and Permissions

  • Extension: Usually needs planning permission and building control sign-off.

  • Garden Room: Often falls under permitted development and most often does not require building regulations approval.

4. Flexibility

  • Garden rooms can evolve with you, use as an office now, convert to a home gym or treatment room later.

  • You can customise size, glazing, doors and layout to suit your exact needs.

  • You can even potentially extend the garden room later down the line!

5. Lifestyle Upgrade

Unlike a traditional extension that adds a room onto your house, a garden room adds space away from it, creating the perfect work/life balance.
