About our swallow raven combi greenhouses
The Swallow Raven Combi combines an 8ft 9in wide ThermoWood® greenhouse with an integrated storage shed. Double doors allow full wheelbarrow access, making this the combi greenhouse for serious growers. Hand-crafted in Rotherham from Scandinavian timber heat-treated at 215°C, every model includes toughened safety glass and automatic roof vents. Full-length slatted staging comes as standard.
Choose from 6 configurations: the Raven 8x4 + 4ft Shed at £4,727, the popular Raven 8x8 + 4ft Shed at £5,326, and up to the Raven 8x12 + 4ft Shed at £6,519. For a narrower option, see the Swallow Kingfisher Combi. Browse our full Swallow Greenhouses range.
Why We Chose This Range
"The Raven Combi is the greenhouse I recommend to customers who want everything under one roof. At 8ft 9in wide, the growing section matches the standard Raven. You get double doors, staging on both sides, and room for a wheelbarrow. Then you walk through an internal door into a proper weatherproof shed. No more carrying tools across the garden in the rain."

Matt's Installation Tip
The Raven Combi is a large building. A "8x8 + 4ft Shed" has a total footprint of approximately 8ft 9in wide by 12ft 6in long. Your concrete base must cover the full footprint. Access to your garden must accommodate delivery vehicles carrying long timber sections. We always check access photographs before confirming your order to avoid problems on installation day.
How much does a Swallow Raven Combi cost?
Prices start from £4,120 for the entry model. The 8x4 + 4ft Shed costs £4,727. The popular 8x8 + 4ft Shed is £5,326. All prices include free UK mainland delivery and professional installation. You pay just 20% deposit, with the balance due after installation.
What is the difference between the Raven Combi and Kingfisher Combi?
The Raven Combi is 8ft 9in wide; the Kingfisher Combi is 6ft 8in wide. The Raven Combi features 3ft 11in double doors for wheelbarrow access. It has room for staging on both sides. The Kingfisher Combi has a single door and suits narrower garden spaces.
What is included in the shed section?
The shed includes a boarded floor, two shelves, and a separate lockable door. The external shed door measures 2ft 6in wide. The polyurethane roof covering lasts 15+ years. A connecting internal door lets you move between greenhouse and shed without going outside.
Does the Raven Combi need wood treatment?
No chemical treatment is required. ThermoWood is heat-treated at 215°C, making both greenhouse and shed sections naturally rot-resistant. The oiled finish comes as standard. A 12-year manufacturer warranty covers all timber against decay.
How long does delivery and installation take?
Allow 8-12 weeks from order to installation. Each Raven Combi is built to order in Rotherham. Installation takes a full day for the larger models. You provide a level concrete base. The factory team handles all assembly, glazing, and shed fitting in a single visit.
