The Swallow Kingfisher is a 6ft wide ThermoWood® greenhouse available in 20 sizes from 6x4 to 6x20. Prices range from £3,154 for the 6x4 up to £6,778 for the 6x20. Every model includes 3mm toughened safety glass, automatic roof vents and full-length slatted staging. Double doors with a mortise lock come as standard. Free professional installation included. Built in Rotherham from rot-resistant ThermoWood® with a 12-year manufacturer warranty.
We fit more Kingfishers than any other Swallow model. The 6ft width suits most garden spaces and the high eaves give you room to work comfortably at the staging. The double doors are wide enough for a wheelbarrow and the mortise lock keeps everything secure.
ThermoWood® is heat-treated at 215°C to remove moisture and resin. It will not warp or rot. Natural, oiled and painted finishes are available. For a wider 8ft greenhouse, see the Swallow Raven. For a painted Kingfisher, see the Swallow Kingfisher Painted range. Browse the full Swallow Greenhouses collection.
The Swallow Kingfisher is a 6ft 8in wide wooden greenhouse built in Yorkshire from Scandinavian thermowood. Prices start from £2,764 for the compact 6x4 oiled model. Sizes run from 6x4 right up to 6x20, so the range suits a small plot or a large allotment. Every model includes 3mm toughened safety glass, automatic roof vents, and free professional installation. The thermowood is heat-treated, not chemically treated, which makes it naturally rot-resistant.
When we install the Kingfisher, the build quality shows in the 58mm glazing bars and the solid mortise lock. The range covers standard, dwarf-wall, and combi greenhouse-plus-shed options, all backed by a 12-year manufacturer warranty.

Why We Chose This Range
"The Kingfisher is our best-selling wooden greenhouse, and the reason is simple. At 6ft 8in wide it fits most gardens without dominating them. I have seen Kingfishers we fitted 12 years ago still standing solid with no rot at all. The thermowood holds its shape through hard winters. That is why we keep recommending it."
Matt, Founder of Greenhouse StoresThe standard oiled finish weathers to a soft silver-grey if you leave it. Re-oil once a year to keep the honey-brown colour instead. Painted models cost more but need less upkeep. For most gardens, I suggest the oiled finish and an annual coat.
Your base must be level to within 5mm across its full area. We check every base by photograph before we schedule delivery. A base that slopes even slightly will make the door bind. Concrete is our preferred option. Budget around £400 to £700 for a professionally laid base.
Best For: a family garden that needs real growing space
Why I Recommend It: the 6x10 is our most popular size, with room for staging one side and a clear path down the centre

No. It is made from Scandinavian thermowood, not cedar. The timber is heat-treated at 215 degrees Celsius, which removes moisture and resin. This makes it naturally rot-resistant without chemical preservatives.
