About Our Swallow Kingfisher Greenhouses
The Swallow Kingfisher is a 6ft wide wooden greenhouse hand-built in Rotherham from Scandinavian ThermoWood®. Heat-treated at 215°C, the timber resists rot and warping without chemical preservatives. Every Kingfisher includes 3mm toughened safety glass, automatic roof vents, and full-length slatted staging. A mortise lock with stainless steel handle comes as standard.
This range spans 20 models from the compact Swallow Kingfisher 6x8 through to extended 20ft lengths. Popular choices include the Swallow Kingfisher 6x10 and Swallow Kingfisher 6x12. For added storage, the Swallow Kingfisher Combi adds an integrated shed extension. Browse our full Swallow Greenhouses range or explore all Wooden Greenhouses.
Why We Chose This Range
"The Kingfisher is our best-selling wooden greenhouse for good reason. At 6ft wide, it fits most garden layouts without dominating the space. When we install these, the build quality is immediately obvious. The ThermoWood glazing bars are 58mm thick, holding the glass firmly even in exposed locations. I have seen Kingfishers we fitted 12 years ago still standing solid with zero rot."

Matt's Installation Tip
Your base must be perfectly level to within 5mm across its full area. We check every base by photograph before scheduling delivery. A base that slopes even slightly will cause the door to bind. Concrete is our preferred option for the 25-30 year lifespan these greenhouses deliver. Budget around £400-£700 for a professionally laid concrete base.
How much does a Swallow Kingfisher Greenhouse cost?
Prices start from £3,154 for the 6x8 oiled model. Painted versions begin at £3,745 for the same size. Most customers choose the 6x10 or 6x12, which offer strong growing space without overwhelming a standard garden. All prices include free delivery and professional installation on UK mainland addresses.
What sizes are Swallow Kingfisher Greenhouses available in?
The Kingfisher is 6ft 8in wide with lengths from 8ft to 20ft. Standard oiled, painted, and dwarf wall variants are available in each length. The 6x10 is the most popular size, providing around 65 square feet of growing space. It fits staging on one side with a clear path down the centre.
Does a Swallow Kingfisher Greenhouse need wood treatment?
No chemical wood treatment is required. ThermoWood is heat-treated at 215°C, which removes moisture and resin from the timber cells. This makes it naturally rot-resistant. The oiled finish that comes as standard simply enhances the appearance. You can leave it to weather to a silver-grey or re-oil annually to keep the honey-brown colour.
What is included with a Swallow Kingfisher Greenhouse?
Every model includes toughened glass, staging, auto vents, and free installation. You get 3mm toughened safety glass, full-length slatted staging, and automatic Bayliss roof vent openers. A mortise lock, stainless steel handle, and 20mm PVC damp barrier are also standard. Free installation is included on UK mainland orders.
How long does delivery and installation take?
Allow 8-12 weeks from order to installation. Swallow's factory team in Rotherham builds each greenhouse to order. Once your base is ready and approved via photograph, they schedule delivery and installation in a single visit. Installation typically takes 4-6 hours depending on the model size.
