How Much Does It Cost to Build a Garden Office?

£10,000 – £40,000

depending on size and spec

Building a garden office costs between £10,000 and £40,000 depending on the size, specification, and whether it is a prefabricated pod or a bespoke timber structure. A basic insulated timber-framed garden office with electrics is at the lower end; a fully fitted, thermally efficient structure with underfloor heating, internet connection, and high-spec cladding sits at the top of the range.

Size - a compact 3x3m office pod costs £10,000-£15,000; a larger 5x4m structure costs £20,000-£35,000+

Build type - prefabricated flat-pack pods are cheaper to build; bespoke timber-framed structures take longer but offer more design flexibility

Insulation standard - a well-insulated garden office costs more upfront but is usable year-round; a basic summer-house grade building is cheaper but cold in winter

Services - running power, internet, and heating to a garden office adds £1,500-£4,000 depending on cable run length and what is installed

Labour vs materials

Erecting a prefabricated garden office typically takes two to four days. A bespoke timber-framed structure takes one to three weeks. Labour usually represents 30-40% of the total project cost.
