Best wooden greenhouses under £600 compared in 2026

Timber greenhouses suit a lot of gardens, and you do not need to spend a fortune to get one. This roundup looks at six wooden models priced from £229.00 to £559.99. They range from small lidded growing frames to walk-in apex and lean-to designs, so the right pick depends on how much room you have and what you want to grow. Glazing includes twin-wall polycarbonate, Perspex and styrene, and warranties range from 12 months on parts to anti-rot guarantees of up to 10 years. This is desk research based on the product details supplied, not hands-on testing.

Our stand-out pick

Evesham Lean-to Pent Wooden Greenhouse 8 x 4

The Evesham Lean-to Pent Wooden Greenhouse 8 x 4 wins on the facts. At £519.99 it is cheaper than the other two Waltons greenhouses, yet it has the largest nominal footprint here at roughly 244 x 122 cm. It is designed to attach to a permanent wall, which makes it a good fit for smaller and urban gardens, and it carries a 10-year anti-rot guarantee where specified for the range. The Mercia 4x6 has a smaller footprint and costs £40 less, and the mini models are a different kind of product altogether. This choice comes from comparing the supplied facts, not from testing.

01 · Best Budget Pick

Rowlinson Hardwood Mini Greenhouse

A low-priced hardwood mini greenhouse with two shelves and two lifting lids for £229.00.

The Rowlinson Hardwood Mini Greenhouse is the cheapest model here and the quickest to put together, with self-assembly estimated at 1 to 2 hours. It stands 144 cm tall on a 120 x 63 cm footprint, so it works as a compact growing station rather than a walk-in greenhouse. The FSC hardwood frame is planed and stained, and the twin-wall polycarbonate glazing is a step up from the single-layer glazing on some of the others. You get two shelves and two lifting lids with adjustable stays, which gives you some control over airing plants. Annual treatment is recommended, and the warranty covers parts for 12 months only.

02 · Best for Tight Spaces

Zest Compact Botanical Greenhouse

The smallest model here, with removable shelves and a pressure-treated softwood frame, but a steep £329.00 for its size.

The Zest Compact Botanical Greenhouse measures just 85 x 40 x 123 cm, so it is aimed at patios, balconies and small corners rather than anyone wanting space to stand inside. Its pressure-treated softwood frame is backed by a 10-year anti-rot warranty, and the two large removable shelves can be taken out to suit taller plants. Glazing is Perspex and the lid opens on a stay for airing. No floor is supplied, so you will need to think about what it sits on. Weighing 40 kg, it is heavier than the larger-footprint Rowlinson mini, and at £329.00 it costs £100 more than that model.

03 · Best Value Walk-in Greenhouse

Mercia Traditional Greenhouse 4x6

A traditional shiplap timber greenhouse with a hinged door and window, priced at £479.99.

The Mercia Traditional Greenhouse 4x6 is the cheapest of the walk-in models here, with a footprint of 192.8 x 124.1 cm and a height of 206 cm. It has a hinged single door and one window, plus dip-treated shiplap timber and styrene glazing. At 94 kg it feels like a more solid structure than the mini models, though it also needs more care when moving the parts. No floor is supplied, so a base needs planning. The 10-year anti-rot warranty is conditional and needs annual retreatment. For £40 less than the Evesham 6 x 4 it offers a similar footprint but comes with a window rather than a roof vent.

04 · Best Traditional Apex

Evesham Wooden Greenhouse 6 x 4

A classic apex shiplap greenhouse with an opening roof vent and a 10-year anti-rot guarantee for £559.99.

The Evesham Wooden Greenhouse 6 x 4 is the traditional apex option in this group, with a nominal footprint of around 183 x 122 cm. It has an opening roof vent for airing and UV-resistant shatterproof styrene glazing, which the retailer describes as shatterproof. The retailer also describes UK-made PEFC timber construction. The floorless drainage design means it sits straight on your chosen base. It carries a 10-year anti-rot guarantee where specified for the range. It costs £559.99, which is £80 more than the Mercia 4x6 for a similar footprint, so the extra spend buys the apex roof and roof vent.

05 · Best for Seedlings and Potting

Evesham Victorian Growhouse 6 x 3

A narrow growhouse with internal potting shelves, though £559.99 is a lot for a 91 cm-deep footprint.

The Evesham Victorian Growhouse 6 x 3 has a nominal footprint of about 183 x 91 cm and is positioned by the retailer for smaller gardens and for growing seedlings or produce. The standout feature is the internal potting shelves, which give you somewhere to work and stage plants without needing separate staging. It has a timber frame with styrene glazing and a 10-year anti-rot guarantee where specified for the range. It is priced at £559.99, the same as the larger Evesham 6 x 4, so you are paying the same money for less floor area. It suits someone who values the shelves and compact shape over sheer space.

06 · Best Lean-to Greenhouse

Evesham Lean-to Pent Wooden Greenhouse 8 x 4

The roomiest greenhouse in the group, designed to sit against a wall, for £519.99.

The Evesham Lean-to Pent Wooden Greenhouse 8 x 4 is built to attach to a permanent wall, which is why it suits smaller and urban gardens where a freestanding apex would take up too much room. Its nominal footprint is about 244 x 122 cm, the largest in this roundup, and it costs £40 less than the Evesham 6 x 4. The frame is timber with styrene glazing, and a 10-year anti-rot guarantee applies where specified for the range. The main thing to check is your garden layout, as it needs a suitable permanent wall to sit against and cannot simply be dropped into the middle of a lawn.
