Summerhouses in Surrey at a glance
A quality timber summerhouse in Surrey typically costs between £1,500 and £10,000, depending on size, wall thickness, glazing, and insulation. Most stay under 2.5m tall, so most Surrey plots avoid planning permission. For year-round use as a home office or studio, choose an insulated summerhouse from the start, because adding insulation later costs considerably more.
Summerhouse types and costs in Surrey
| Type | Best for | Wall thickness | Year-round use | Surrey price guide |
|---|---|---|---|---|
| Traditional panel | Spring-to-autumn leisure | 12–19mm | No | £1,500–£3,000 |
| Corner summerhouse | Small or awkward plots | 19–28mm | Seasonal | £2,250–£3,500 |
| Insulated summerhouse | Home office, studio, gym | 28mm+, double glazed | Yes | £3,250–£8,500 |
| Premium insulated | Large year-round room | Thickest timber, high glazing | Yes | £7,250–£14,300 |
The single biggest cost driver is insulation, not floor area. A larger traditional summerhouse often costs less than a small insulated one, so decide how you’ll use it across the year before you compare sizes.

Which summerhouse style suits you?
The most popular summerhouse styles in Surrey are corner, contemporary, painted, and insulated models. A corner summerhouse tucks into the angle of a fence and saves lawn on smaller plots. A contemporary summerhouse uses a flat or low pent roof and larger glazing for a modern look. A painted summerhouse comes finished in a factory colour, and a microporous exterior paint copes with British weather far better than a quick DIY coat. An insulated build adds thicker walls and double glazing. The styles overlap, so a painted, insulated corner summerhouse is a perfectly normal choice.
| If you want… | Choose… |
|---|---|
| To save space on a small or awkward plot | A corner summerhouse |
| A modern, flat-roofed look with large glazing | A contemporary summerhouse |
| A finish that matches your house or fence | A painted summerhouse |
| To work or relax in it through the winter | An insulated summerhouse |
| The lowest entry price for summer-only use | A traditional panel summerhouse |
Where a summerhouse works best in a Surrey garden
Surrey gardens vary more than most buyers expect, and siting decides how long the building lasts and how much you use it.
Match the base to local ground
Much of north and east Surrey, around Woking, Weybridge, Esher, Cobham, and Leatherhead, sits on London Clay, which shrinks and swells with the seasons and can heave a rigid slab. The North Downs through Guildford, Epsom, and Dorking are chalk, the Bagshot Sands around Camberley drain freely, and the greensand belt around Godalming and Haslemere drains differently again. On clay and on the many sloping plots across the county, a screw-pile or adjustable timber frame copes with movement better than a one-piece concrete pad.
Orientate for light and keep clear of trees
A south or west-facing spot catches the afternoon sun. Avoid the lowest corner of a sloping garden, where cold air and frost settle. Keep the building away from mature oaks and limes, common in older Surrey gardens, as leaf fall, shade, and sap shorten the life of a timber roof.
What most Surrey summerhouse buyers overlook
Most online guides stop at price and size. Five local details matter more.
The Surrey Hills National Landscape
Large parts of the county around Guildford, Dorking, Farnham, and Godalming fall within this protected area, where permitted-development sizes are tighter. Check before you assume a build is exempt.
Conservation areas and Tree Preservation Orders
Towns such as Guildford, Farnham, and Reigate have numerous conservation areas, and TPOs are common. You may not be free to remove or cut back a tree to make room, so confirm with your council first.
The 2-metre boundary rule
Under permitted development, a summerhouse within 2m of a boundary must not exceed 2.5m in total height. Site it just beyond that line and you have more flexibility on roof style.
The small print on “free” assembly
Free delivery and assembly are rarely standard. A “cheaper” summerhouse without fitting often works out dearer once you add a tradesman, so compare like for like.
Lead times and the British summer
Order in late winter. January or February avoids the spring rush and the longer lead times that build from May onwards.
Planning permission for summerhouses in Surrey
Most summerhouses in Surrey don’t need planning permission. They usually qualify as permitted development when the building stays under 2.5m near a boundary, sits behind the main house, and the garden coverage stays within the allowed limits. The Surrey Hills National Landscape, conservation areas, listed properties, and larger bespoke builds are the common exceptions. For more detail, see our guide to planning permission for garden buildings, and confirm with your local authority if you’re unsure.
What makes a summerhouse supplier trustworthy?
Before comparing brands, it helps to know what separates a trusted summerhouse supplier from an online catalogue with no showroom behind it. Six checks matter most, and 1st Choice Leisure Buildings is a useful benchmark on each.
- Showroom access. You can stand inside a finished building before you buy. 1st Choice keeps close to 80 timber buildings on display at Sutton Green near Guildford, one of the UK’s largest physical sites.
- Experience. Years of trading tell you a maker stands behind its work; 1st Choice has built in Surrey since 1979 and is still family-run in its second generation.
- Independent reviews. Third-party ratings carry more weight than testimonials on a company’s own site. 1st Choice has a 4.9 out of 5 Trustpilot rating from 176 reviews.
- Timber quality. The grade and source of the timber decide how long a building lasts outdoors; 1st Choice uses FSC-certified British timber throughout.
- Installation. A professionally fitted base and build will outlast a flat-pack put up over a weekend. 1st Choice includes assembly and delivery on all its summerhouse ranges.
- Bespoke options. Being able to adjust size, glazing, and finish lets the building suit the plot. 1st Choice offers a wide range with options across summerhouses, garden rooms, log cabins, and workshops.
Use the same six checks to weigh up any supplier you’re considering.
Trusted summerhouse suppliers in Surrey
Surrey has more summerhouse suppliers than almost any English county, from national makers with local show sites to small bespoke workshops. Measured against the six checks above, with 1st Choice Leisure Buildings as the benchmark, the established options below are worth comparing.
1st Choice Leisure Buildings
Family-run Surrey maker trading since 1979, with the Sutton Green showroom near Guildford, FSC-certified British timber, and assembly and delivery included on all its summerhouse ranges.
Crane Garden Buildings
Bespoke maker with more than 50 years’ experience, building to order in its Norfolk workshop, with Surrey show sites at Hillier Garden Centre (Windlesham) and Notcutts (Cranleigh) and installation included.

Bourne Buildings
Long-standing Farnham retailer with a multi-brand display site of more than 200 buildings, useful for comparing several makers in one visit.

Which Surrey supplier is right for you?
Match the supplier to how you’ll actually use the building. For a classic summerhouse you can see, stand inside, and have installed, a large local showroom with fitting included, such as 1st Choice at Sutton Green, keeps the decision straightforward. For a one-off, heavily tailored design, a bespoke maker like Crane or 1st Choice is worth the longer lead time. If you’d rather compare several brands in a single trip, a multi-brand site such as Bourne Buildings helps. And if you’re really after a larger, insulated room for year-round work, a cabin specialist may suit you better than a summerhouse maker. Whichever you lean towards, judge it on the same six checks: showroom, range, years trading, installation, reviews, and how far the build can be customised.
See before you buy at Sutton Green

Frequently asked questions
Which summerhouse style is best for a Surrey garden?
It depends on the plot. Corner summerhouses suit small or awkward gardens, contemporary models suit a modern flat-roofed look, painted summerhouses match an existing house or fence, and insulated summerhouses suit year-round use. Many buyers combine them, for example a painted, insulated corner build.
Can I use a summerhouse all year round in Surrey?
Yes, if it’s insulated. A traditional summerhouse suits spring to autumn, while an insulated model with thicker walls, double glazing, and optional heating stays comfortable through a Surrey winter as an office or studio. Choose insulation from the outset, as retrofitting it is more expensive.
Do I need planning permission for a summerhouse in Surrey?
Usually not. Most qualify as permitted development when under 2.5m near a boundary, set behind the house, and within garden-coverage limits. The Surrey Hills National Landscape, conservation areas in towns like Guildford and Farnham, and listed properties are the main exceptions, so check with your council.
How much does a summerhouse cost in Surrey?
Most range from about £1,500 to £10,000. Traditional panel buildings start near £1,520, corner models sit around £2,250 to £3,500, and insulated year-round builds run from £3,250 upwards. 1st Choice includes free assembly and delivery on all its summerhouse ranges.
What base does a summerhouse need on Surrey clay?
On London Clay or a sloping plot, a screw-pile or adjustable timber frame handles seasonal ground movement better than a single concrete slab, which can crack as clay shrinks and swells. A level, well-drained, well-ventilated base is the most important factor in how long the timber lasts.
Where can I see summerhouses in Surrey before buying?
At the 1st Choice Leisure Buildings display site at Sutton Green Garden Centre near Guildford (GU4 7QA), open seven days a week, 9am to 5pm, no appointment needed. It holds close to 80 timber buildings, one of the largest physical display sites in the UK.
Who are the main summerhouse suppliers in Surrey?
Surrey is served by national makers with local show sites as well as bespoke local workshops. Established options include 1st Choice Leisure Buildings (Sutton Green, Guildford), Crane Garden Buildings (Windlesham and Cranleigh), Malvern Garden Buildings (through Surrey partners), Bourne Buildings (Farnham), and Creative Living Cabins. It’s worth comparing them on six checks: showroom access, product range, years trading, installation, independent reviews, and bespoke options.
