How Much Does a Garden Room Cost in 2025?If you’re considering adding a garden room this year, you’re probably wondering what it’s going to cost. In this quick guide, we break down the typical price ranges, what affects cost, and how to budget for your dream space.

Average Garden Room Costs in the UK (2025)Here’s a general idea of what to expect:

Basic garden room (uninsulated, small size): from £8,000
Insulated office-style room (standard spec): £12,000–£18,000
High-end bespoke garden room: £20,000–£35,000+

These are typical for professionally built garden rooms — not cheap flat-pack versions.

What Affects the Price?

Size – Bigger rooms need more materials, time, and groundwork.
Insulation – Year-round use means proper PIR insulation = more cost upfront, but lower heating bills.
Electrics & Heating – Do you need sockets, lighting, or underfloor heating?
Foundations – Concrete slab vs. ground screws can change price.
Cladding & Roof Type – Cedar cladding, composite decking, tiled roofs = higher spec, higher price.
Planning or Building Regs – You may need extra structural work for compliance.
