Swallow Greenhouses

About Swallow Greenhouses

Swallow Greenhouses represent premium British craftsmanship in timber greenhouse construction. Manufactured in Yorkshire using heat-treated ThermoWood, these structures offer serious gardeners a rot-resistant alternative to standard timber options. Our collection includes the compact 4ft wide Swallow Lark Wooden Greenhouses for smaller spaces, the popular 6ft wide Swallow Kingfisher Wooden Greenhouses for most gardens, and the spacious 8ft wide Swallow Raven Painted Wooden Greenhouses with professional spray-painted finishes.

Each Swallow Greenhouse features toughened safety glass, automatic roof vents, and your choice of single or double locking doors. Structures range from 4ft to 30ft in length, accommodating everything from patio growing to serious horticultural projects. Every purchase includes free UK mainland delivery and professional installation — no flatpack assembly required. With 16 years’ experience selling and installing Swallow Greenhouses, we back each structure with a comprehensive 12-year warranty.

The ThermoWood Difference

Choosing the Right Swallow Greenhouse

Start by measuring your available space and considering your growing ambitions. Swallow Kingfisher 6x8 Wooden Greenhouses suit most UK gardens, providing 48 square feet for tomatoes, cucumbers, and propagation. Serious growers choose 8ft-wide models like the Raven (from £4,995), which accommodate full-length staging on both sides. For unique garden layouts, explore Swallow T Shaped Wooden Greenhouses or check our Combi Shed Greenhouses collection that combine growing and storage space.

Frequently Asked Questions

• How much do Swallow Greenhouses cost?

  Swallow Greenhouses range from £2,495 for a 4ft Lark to £12,000+ for 30ft professional structures. Most customers choose 6x8 or 6x10 models (£3,500–£6,000) which provide ample growing space with painted finishes. All prices include free UK mainland delivery and professional installation.

• What maintenance do Swallow Greenhouses need?

  ThermoWood construction means no annual wood treatment is required. Simply clean the toughened glass seasonally and oil hinges occasionally. Painted models maintain their finish for 15–20 years without repainting, though replacement paint is available from Greenhouse Stores. This is significantly less maintenance than aluminium greenhouses that develop condensation issues.

• How are Swallow Greenhouses installed?

  Professional installation is included free with every Swallow Greenhouse. After you order and pay your 20% deposit, the factory contacts you to confirm your base is ready. Your greenhouse is then manufactured fresh, and specialist fitters deliver and install it in a single day. You pay the remaining 80% only after installation is complete.

• Are Swallow Greenhouses better than aluminium?

  Swallow Greenhouses offer superior insulation (timber is 400% more thermally efficient than aluminium) and won’t develop the condensation drip that plagues metal structures. ThermoWood resists rot for decades without treatment. The trade-off is higher initial cost (£3,500–£6,000 vs £800–£2,000 for aluminium) and slightly more weight requiring a concrete or paving slab base.

• What’s the difference between oiled and painted Swallow Greenhouses?

  Oiled Swallow Greenhouses showcase ThermoWood’s natural grain and cost £500–£800 less than painted versions. Painted models receive three spray-booth coats creating a showroom finish in 10 colours that hides grain completely. Both options last 25–30 years, but painted finishes require less frequent maintenance (re-oiling every 2–3 years vs repainting every 15–20 years).

• Do Swallow Greenhouses come with a warranty?

  Every Swallow Greenhouse includes a 12-year manufacturer’s warranty covering structural integrity and ThermoWood frame. Toughened safety glass, hinges, and automatic vent openers are covered for 2 years. Greenhouse Stores has been an authorised Swallow retailer for 16 years, and we handle all warranty claims directly.
