Choosing a Swallow Kingfisher Combi: Quick Guide

📏 Plan your footprint first: Size is your first consideration. Measure your available space and subtract at least 2ft on all sides for maintenance access. The Combi design means you’re getting approximately 60% greenhouse and 40% storage shed in one footprint. Note: The model size (for example “6x8”) refers to the length and width of the greenhouse section only. The 4ft shed is an addition.

Size reference:

  • “6x8” = approx. 6ft wide × 8ft long (Greenhouse)
  • “4ft Shed” = approx. 6ft wide × 4ft long (Shed)

A “6x8 + 4ft Shed” model, therefore, has a total footprint of approximately 6ft 8in wide by 12ft 7in long. This gives you around 48 square feet of greenhouse plus 24 square feet of weatherproof storage – roughly equivalent to buying a 6x8 standalone greenhouse and a 4x6 separate shed.

💷 Pricing and value: Prices for the Combi range start from £3,888 for the 6x4 + 4ft model, rising to around £4,520 for the largest 6x10 version. That’s including delivery and installation – two services that would typically cost £400–£600 separately with most competitors. The ThermoWood construction requires virtually no ongoing treatment, saving you dozens of hours of maintenance over a decade compared to pressure-treated timber greenhouses that demand annual treatment.
🔧 Base preparation: Consider a concrete base or paving slab foundation before installation. The base needs to be perfectly level and extend the full dimensions of your chosen model. Installation typically takes 6–8 hours, and you’ll pay only 20% deposit upfront – the balance isn’t due until after your Swallow Kingfisher Combi Greenhouse is standing complete in your garden.

Frequently Asked Questions

  • What exactly is a Swallow Kingfisher Combi Greenhouse?

    A Swallow Kingfisher Combi Greenhouse is a dual-purpose garden building that combines a traditional ThermoWood greenhouse with an integrated storage shed in one continuous structure. The greenhouse section features 3mm toughened safety glass for optimal plant growing, while the shed portion includes a boarded floor, fitted shelving, and weatherproof polyurethane roofing. You access the shed directly from inside the greenhouse, keeping all your gardening tools and supplies conveniently to hand without needing a separate building.

  • How much do Swallow Kingfisher Combi Greenhouses cost?

    Swallow Kingfisher Combi Greenhouses start from £3,888 for the 6x4 + 4ft Shed model, with prices ranging up to £4,520 for the 6x10 + 4ft Shed version. These prices include FREE UK mainland delivery and professional installation – services worth an estimated £400–£600. You’ll also get a 12-year timber warranty, automatic roof vents, full-length staging, and mortice-lock security as standard. Payment terms are flexible: just 20% deposit when ordering, with the balance due only after installation is complete.

  • How long does the ThermoWood construction actually last?

    The ThermoWood timber used in Swallow Kingfisher Combi Greenhouses carries a 12-year manufacturer’s warranty against timber rot, but these structures are expected to last 25–30 years with basic maintenance. This impressive lifespan is thanks to a ~212°C heat-treatment process that removes moisture and resins, making the timber naturally resistant to decay without chemical preservatives. To maintain its appearance, the timber only needs re-oiling or repainting every 3–5 years – far less frequent than standard treated timber, which usually requires annual attention.

  • Do I need to treat or paint my Swallow Kingfisher Combi?

    Your Swallow Kingfisher Combi Greenhouse arrives pre-oiled and ready to use immediately – no initial treatment required. The natural oiled finish should be refreshed every 3–4 years to maintain weather protection and appearance. Alternatively, you can order any model in one of 10 optional Farrow & Ball paint colours for an additional cost that varies by size. Painted models need repainting every 5–6 years to maintain protection.

  • What base preparation is needed for a Swallow Kingfisher Combi?

    Your Swallow Kingfisher Combi Greenhouse requires a firm, level base that extends the full footprint of your chosen model. A concrete base provides the most stable foundation and lasts 30+ years, while paving slabs offer a more budget-friendly option at roughly 60% of the concrete cost. The base must be perfectly level (within 5mm across the entire area) to prevent door misalignment and glazing stress. Professional installation is included in your price, but base preparation is your responsibility and should be completed before the delivery date.

  • Why choose ThermoWood over pressure-treated timber greenhouses?

    The main advantage is stability and longevity. Standard pressure-treated timber can warp, twist, or split after 5–7 years, causing doors to stick and glazing bars to misalign. ThermoWood’s heat treatment makes it dimensionally stable and far more resistant to rot, meaning your greenhouse doors will continue to close smoothly and the frame will remain solid for decades. These structures last up to ~40% longer than standard treated timber buildings, and you’ll save hours of maintenance because ThermoWood only needs re-oiling every 3–5 years rather than yearly treatment.
