Garden Buildings

Updated

Garden buildings cover everything beyond a basic shed: log cabins for year-round home offices, summer houses for warm-month garden rooms, greenhouses for serious growers, pergolas and gazebos for outdoor seating shelters. The category has grown sharply since 2020 as the WFH market pushed homeowners to build outdoor working space. Aosom UK, Archiproducts UK and Buy Sheds Direct between them stock over 21,000 garden building products spanning £3 small accessories up to £19,749 substantial timber installations. The decision points across the category share themes: wall thickness for year-round use (44mm-70mm walls turn a summer building into a four-season space); roofing material (felt vs EPDM rubber, with EPDM lasting 25-30 years vs 5-7 for felt); and planning permission rules that depend on size, height, and proximity to property boundaries. The grid below filters by building type, size and budget so you can size the project to the garden you actually have.

Frequently asked questions

Do I need planning permission for a garden shed in the UK?
Sheds under 2.5m to the eaves, less than half the original garden area, and not in front of the principal elevation fall under permitted development for most homes. Listed buildings, conservation areas and AONBs need consent regardless of size. Always check with your local planning authority before ordering.
What size shed do I need for a small garden?
A 6 x 4ft (1.8 x 1.2m) shed holds a lawnmower, garden tools and a couple of crates. 8 x 6ft fits a mower plus bicycles. 10 x 8ft starts handling workshop use. Add 30cm of clearance on every side for treatment access.
Which lasts longest: wooden, metal or plastic shed?
Pressure-treated wood with annual stain treatment lasts 15 to 25 years. Galvanised metal lasts 20 to 30 but condenses inside and rusts at any scratch. Plastic (HDPE) lasts 15 to 20 with zero maintenance but flexes in high wind. Match to how often you will re-treat.
Do I need a base under a garden shed?
Yes, in every case. A timber shed sat on bare soil rots from below within 3 to 5 winters. Options: paving slabs on a sand bed, a concrete pad, or a plastic grid base over compacted hardcore. The base should sit 5 to 10cm above surrounding ground for drainage.
How do I anchor a shed against UK winds?
Storm straps (galvanised steel strips) bolt the shed frame down to ground anchors driven into a concrete pad. A 6 x 4 shed needs 4 anchor points; an 8 x 6, 6 points. For exposed coastal or hilltop gardens, add corner bracing inside the frame. Cheap insurance against £400 of damage.
What is the difference between a summerhouse and a log cabin?
Summerhouses are typically single-skin tongue-and-groove (12 to 16mm walls), unheated, used spring to autumn for sitting out. Log cabins are double-stacked notched logs (28 to 44mm walls), insulatable, year-round office or guest space. Cabin foundations and insulation push the cost from £1,500 to £5,000-plus.
