We have installed more than 1,200 wooden greenhouses across the UK since 2017, almost all of them from two UK-trusted brands: Swallow (handcrafted in Yorkshire from Finnish ThermoWood® baked at 215°C) and Lichfield (UK-built redwood pine on a 20mm PVC damp-proof plinth). Prices run from £2,089 for an entry-level 6x4 Lichfield up to £3,888+ for an 8x20 Swallow Raven. Every model includes 3mm toughened safety glass, automatic roof vents, full-length staging on all Swallow ranges, and a 12-year manufacturer warranty. Free professional installation comes with every Swallow. Our own two-person team fits a 6x8 in 4-6 hours.
We have been installing timber greenhouses across the UK since 2012 and currently fit around 180 wooden greenhouses every year. Most customers spend between £3,000 and £4,500. Lead times sit at 8 to 12 weeks from order to install, and longer in spring, when we book out by mid-January. The most popular size we install is a 6ft wide wooden greenhouse, which accounts for just over 60% of orders. If timber is not a must-have for you, aluminium greenhouses cost less. For wall-mounted builds see our lean-to greenhouses. Read our concrete base guide before you order. A timber frame holds heat better than aluminium overnight, which matters most for winter growing.
We have 255 wooden greenhouses in stock, with prices from £2,575. Every model here is built from Swallow thermowood, a heat-treated timber that resists rot far better than untreated softwood. We have fitted these greenhouses across the UK since 2012, so we know how they weather. The wood holds warmth well, which helps plants through cold spring nights. Browse the full Swallow greenhouse range to compare sizes.
Thermowood needs almost no upkeep. A light coat of oil every few years keeps the finish looking smart. We fit every Swallow wooden greenhouse free of charge south of Glasgow, so you skip the build day yourself. If you prefer a metal frame, see our aluminium greenhouses. For a more decorative timber look, the Victorian greenhouses add traditional styling.
Why We Chose This Range
"I picked Swallow because the thermowood frame keeps heat in better than any aluminium frame I have fitted. On a cold March morning the inside stays noticeably warmer. The timber also takes the weight of heavy guttering and shelving without flexing."
— Matt, Founder of Greenhouse Stores💡 Tip: Site your wooden greenhouse on a level base before delivery. A slab or concrete pad keeps the frame square and stops damp rising into the timber.
Give the thermowood a coat of clear timber oil within the first season. It seals the joints and keeps the grain looking fresh. We do this on every install and the wood lasts for years.
Best For: Most home growers wanting a warm, good-looking greenhouse with free fitting.
Why I Recommend It: The Kingfisher 6x4 suits the average plot and we fit it free south of Glasgow. The thermowood frame holds heat well and the toughened glass is safe near children.
