How much is a Garden Office
A garden office in the UK typically costs between £5,000 and over £30,000, with the average cost for a purpose-built model around £12,000. The final price depends heavily on the size, materials, level of insulation, and additional features like electrical wiring and plumbing.
Cost Breakdown by Type & Size
Garden offices can be broadly categorised into budget/pre-built, standard, and bespoke options.
Entry-level pre-fab/DIY kits
Basic shell, requires self-assembly or extra labour costs, often minimal insulation. Based on a garden shed or summerhouse. £1,100 - £7,000
Purpose-built/Standard design
High quality, often pre-made off-site, insulated walls/roof/floor, double-glazed uPVC windows/doors. £12,000 - £25,000
Bespoke/High-end
Custom design, premium materials (cedar, aluminium), built on-site, often includes full electrics and foundations. £14,000 - £75,000+
Garden Office Pods
These are prefabricated and delivered to your home fully assembled. They are a good option for those who want a quick installation process. Our range of garden pods and offices are delivered, fully assembled and designed to be a private workspace. They are a fully insulated, high end product at a purpose built price, and also include electrics.
Additional Costs to Consider
The base price of the structure is not always the final cost. Be sure to budget for the following:
-
Foundations: A level, stable base is essential. Costs can range from £85 per square metre for a timber frame base up to £200 per square metre for a concrete base, or £2,200 - £3,000 for ground screws on uneven ground.
-
Electrics and Internet: Professional electrical installation can add £500 to £2,000, depending on the complexity, and what's included in your garden office build. You may also need a Wi-Fi extender or a hardwired (Cat5e/6) connection.
-
Plumbing: Adding a toilet or shower room can substantially increase costs (a toilet typically adds £1,100–£2,200; a shower room £3,300).
-
Installation/Labour: While many kits include installation, some may charge a separate fee of £750 to £2,500, or for bespoke builds, daily labour costs for a team can range from £400 to £1,100.
-
Planning Permission/Building Regulations: Most garden offices fall under permitted development, but if a planning application is needed, fees can be around £200, plus potential architect fees for detailed plans (£440-£1,650).
Self-build kits
For those with DIY experience, a kit can be a more affordable option. They come with all the components needed for assembly, and some suppliers offer installation services.
You can purchase a garden office as a pre-built pod, a self-assembly kit, or have a builder create a bespoke design. Many garden offices do not require planning permission if they meet specific criteria, such as a maximum height and being built for "incidental" use, but it's important to check with your local council.
