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+
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).
Garden Office Pods
Our pods are prefabricated and delivered to your home fully assembled. They are a good option for those who want a quick installation process at a cost effective price and we have a large range of designs and sizes. All of our garden rooms are fully insulated and also include electrics, and considered to be a high end product at a sensible price.
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. They do however take quite a bit of time to construct on site, and are not often treated against rot and decay. We usually find the experienced DIY enthusiast leaves the construction to the experts but can't wait to add the personal touches with decoration and landscaping.
Should you wish to purchase a garden office as a pre-built pod, please contact us for details. This is certainly an option and has previously been done on several occasions especially in the Channel Islands and Scotland. The beauty of pre-constructed panels ensures that you are simply putting together a jigsaw puzzle, which is much more cost effective than building from scratch with materials from the DIY centres.
