Garden Room Pricing
Every HG Spaces garden room is individually designed around your property, your garden and how you want to use the space.
Because no two projects are the same, we don’t work from a fixed catalogue of standard buildings. Instead, we provide a clear, detailed quotation based on the size, specification, finishes and level of work required.
As a guide, our fully installed bespoke garden room projects typically start from £16,499 +VAT with larger or more specialist spaces such as golf simulator rooms, home gyms, entertainment rooms and swim spa buildings priced individually.
Our quotations can include everything from groundwork and construction through to glazing, electrics, heating, flooring and interior finishes — giving you one team to manage the project from start to finish.
