About Our 8ft Wide Wooden Greenhouses
Our 8ft wide collection features 87 Swallow greenhouses across five ranges. The traditional Raven starts from £2,989 for the compact 8x4 dwarf wall model. Victorian Eagles, T-shaped Mallards and Swans, and Rook potting sheds extend the range up to £17,956 for the largest painted models. Every model includes free professional installation by our fitting team.
At 2660mm (8ft 9") wide, these greenhouses suit medium to large gardens. Double doors come as standard on every 8ft model, giving easy access for wheelbarrows and staging. Choose natural Thermowood, factory-painted finishes in 8 colours, or dwarf wall configurations that sit on a brick base for a traditional look. If you need a narrower greenhouse, see our 6ft wide wooden greenhouses or 5ft wide wooden greenhouses for tighter spaces.
Why We Chose This Range
"The 8ft width is where Swallow really shines. You get double doors, proper headroom, and enough width for staging down both sides with a comfortable working path in the middle. The Raven is our biggest seller because it gives you a serious greenhouse at a fair price. But if you want something special, the Eagle with its Victorian ridge cresting and the T-shaped Mallard are in a different league. I've installed hundreds of 8ft Swallows and the build quality is the same whether you pick a £3,000 Raven or a £15,000 Swan."
— Matt, Founder of Greenhouse StoresOur 8ft Wide Wooden Greenhouse Ranges

Tip: The 8ft (2660mm) width gives you around 800mm staging on each side with a 1000mm centre path. That's wide enough for two people to work side-by-side. The double doors on every 8ft model mean you can wheel in a loaded barrow without turning sideways. For the best growing results, position your greenhouse with the ridge running east-west for maximum winter light.

Matt's Installation Tip: Base for an 8ft Swallow
Every 8ft wide Swallow needs a solid, dead-level base. For Ravens up to 8x12, paving slabs on compacted sand work well and cost £150-£250 depending on length. For anything 8x14 and above, I'd always go with a concrete pad because the extra weight and length magnify any unevenness. Dwarf wall models need a brick plinth built first, level to within 5mm. We check every diagonal before we start bolting the frame down. Read our concrete base guide for full instructions.
All 8ft Swallow greenhouses include free UK mainland delivery and free professional installation. The Raven starts from £2,989 for the 8x4 dwarf wall, making it the most accessible 8ft wooden greenhouse on the market. Painted upgrades add roughly 30% to the natural Thermowood price. Every model comes with a 12-year structural guarantee from Swallow covering frame and base.
Standard features across all 8ft ranges include toughened safety glass, automatic roof vent openers, integral aluminium gutters, double doors with mortise locks, and stainless steel fixings. The Finnish Thermowood frame needs no chemical treatment and resists rot for decades. Read our wooden vs aluminium greenhouse comparison if you're weighing up materials. For seasonal maintenance, our winter care guide covers protecting wooden frames year-round.
Frequently Asked Questions
-
How much do 8ft wide wooden greenhouses cost?
Our 8ft Swallow greenhouses range from £2,989 to £17,956. The traditional Raven starts at £2,989 for the 8x4 dwarf wall model. Victorian Eagles begin at £8,847. T-shaped Mallards from £9,829 and Rook potting sheds from £4,259. Painted finishes add roughly 30% to the natural price. All prices include free delivery and free professional installation.
-
What is the difference between the Raven, Eagle, Mallard, Swan, and Rook?
Five ranges covering traditional, Victorian, T-shaped, and potting shed designs. The Raven is a traditional straight greenhouse and the best value. The Eagle adds Victorian ridge cresting and decorative finials. The Mallard is T-shaped with an extra wing for workspace. The Swan combines T-shape with Victorian styling. The Rook is half greenhouse, half timber potting shed. All use the same Finnish Thermowood frame and toughened glass.
-
Do 8ft wooden greenhouses include free installation?
Yes, every 8ft Swallow greenhouse includes free professional installation. Our team delivers and builds the greenhouse on your prepared base. A standard Raven takes 4-5 hours to install. Larger T-shaped models and potting sheds take 6-8 hours. Installation covers the frame, glazing, doors, vents, gutters, and staging.
-
What base does an 8ft wooden greenhouse need?
All 8ft models need a level, solid base such as concrete or paving slabs. Paving slabs on compacted sand suit models up to 8x12. Longer greenhouses need a concrete pad. Dwarf wall models require a brick plinth built to Swallow's specifications. The base must be level to within 5mm across the diagonals. Our installation team checks this before starting the build.
-
What can I grow in an 8ft wide greenhouse?
An 8ft greenhouse supports a full range of crops year-round. The double-door width and staging on both sides let you grow tomatoes, cucumbers, peppers, and aubergines in summer, then switch to salads, herbs, and overwintering crops in autumn. An 8x12 Raven comfortably handles 12-16 cordon tomato plants. The larger T-shaped Mallard gives you a dedicated propagation area in the wing.
-
How long does a Thermowood greenhouse last?
Finnish Thermowood frames last 30+ years without chemical treatment. The heat-treatment process removes moisture and changes the wood's cell structure, giving natural resistance to rot, fungus, and insects. Swallow backs every model with a 12-year structural guarantee. You can apply optional wood oil every 4-5 years to keep the natural colour, or let it weather to silver-grey. Read our guide on plants that can damage greenhouse frames to protect your investment.
-
Should I choose a standard, dwarf wall, or painted greenhouse?
Standard Thermowood is the best value and needs zero maintenance. Dwarf wall models sit on a brick plinth (you build the wall, we fit the greenhouse on top) for a traditional estate look and extra thermal mass. Painted models get a factory-applied finish in 8 colours that lasts 8-10 years before recoating. The Thermowood underneath gives identical rot resistance in all three configurations.
