The Swallow Robin is a unique 5ft 8in wide ThermoWood® greenhouse, between the 4ft Lark and 6ft Kingfisher. Choose from 10 sizes with prices from £2,669 to £5,171. Every model includes 3mm toughened safety glass, automatic roof vents, full-length slatted staging and a mortise lock door. Hand-built in Rotherham with a 12-year warranty and free professional installation.
We recommend the Robin for gardens where 4ft feels too tight but 6ft is too wide. The 5ft 8in width is unique to Swallow. It gives enough bench space for seed trays on both sides with a clear walkway down the centre.
ThermoWood® is heat-treated at 215°C, removing moisture and resin. It resists rot without chemical preservatives. For a narrower model, see the Swallow Lark at 4ft. For the next size up, see the Swallow Kingfisher at 6ft. A factory-painted finish is also available in the Swallow Robin Painted range.

Why We Chose This Range
"5ft wide greenhouses are rare. I chose the Robin because it delivers the thermal mass of wood in a footprint reserved for metal frames. At 5ft 8in, it uses almost all of a 6ft gap for growing space. When we fit these in terraced gardens, customers are always surprised how much room they get inside."
, Matt, Founder of Greenhouse StoresAll Robin models are 5ft 8in (1728mm) wide. Prices include free UK mainland delivery and professional installation.

Because the Robin is delivered fully assembled in sections, your base must be level to within 5mm. Unlike aluminium frames that can flex slightly, ThermoWood is rigid. If the base is not level, the doors will not align. Measure your width carefully. The Robin needs 1728mm for the greenhouse plus 300mm clearance on at least one side.
Prices start from £2,669 for the 5x4 oiled model. The popular 5x8 costs £3,042 in oiled finish, or £4,014 painted. All prices include free UK mainland delivery and professional installation. You pay just 20% deposit when ordering, with the balance due after installation.
The Robin is 4 inches narrower than a 6ft model but uses wood, not aluminium. At 5ft 8in wide, it fits in spaces where a standard 6ft 8in Kingfisher will not go. You lose only about 15% of internal space compared to the Kingfisher. In return, you gain timber construction in a width no other wooden greenhouse offers.
No chemical treatment is required. ThermoWood is heat-treated at 215°C, making the timber naturally resistant to rot, warping, and insect damage. The oiled finish improves the appearance. A 12-year manufacturer warranty covers all timber against decay.
Every Robin 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.
Internal width is approximately 5ft 2in (1575mm). This provides room for staging on one side and a clear walkway. Eaves height is 5ft 8in with a ridge height of 7ft 6in, giving comfortable standing headroom throughout.
