How these picks were chosen
The best greenhouse with base, in this set, is the row that matches a job and still shows its limit. Footprint comes first, then the base pattern, then the cover, then the review sample. The highest scaled score is the Bamworld timber mini at 4.6 from 109 reviews and about £22.99. That is the top pick for a small rack, and it is the wrong answer if you need to stand inside. The best value line is the extra-wide DIVCHI at 4.5 from 325 reviews and about £33.29, because it is a strong sub-£45 shelf house with more UK reviews than the timber winner. The lean-to at about £157.69 and 3.6 from 52 reviews stays in the set as the only galvanised steel base with polycarbonate panels, and the small sample is the reason it is not the default.
Two VOUNOT walk-ins share one problem you should see before you trust the stars. Both pages show 4.2 from 1,636 reviews, and the captured UK texts open the same way. That is one family sample pasted across two sizes, not 3,272 independent opinions. Use the centimetres, not the duplicated count.
Best when you want to stand and pot
If you need room to stand, the square VOUNOT at about £44.49 is the one to shortlist. It is listed at 143 cm by 143 cm by 195 cm and about 10 kg, with eight shelves the bullets rate at 10 kg each, two vents, a zip door and a 135 g/m² polyethylene cover. The base pattern is metal feet plus a skirt, with four ropes, four ground anchors and 32 cable ties. Reviewers in the shared file like the mesh flap on hot days and the standing room. They also report zips that open at the sides and tie-downs that snap, and they tell you to push the shelf bars fully home or the shelves leave gaps. One buyer weighs the door hem with bricks.
Skip the square if your patio is a path. The narrow VOUNOT is the same family at 143 cm by 73 cm by 195 cm and about £33.49, with four shelves and a listed weight of 6.5 kg. Take that one when 73 cm is all the depth you have. Skip it if you need the spec and the bullets to agree: the spec says a plastic frame and the bullets say painted metal. The Outsunny walk-in at about £37.99, 4.4 from 971 reviews, is the other narrow stand-up, about 141 cm by 72 cm and 191 cm, with four guy ropes, four ground nails and a 10 cm bury edge. A senior reviewer built it alone in about 90 minutes. The limit is the door: ties and the zip are a repeated one-season complaint, and the page caps load at 15 kg. Skip the Outsunny on paving unless you will add weight, because nails and a bury skirt assume soil.
Best for a tight patio or a balcony
When you cannot walk in, the extra-wide DIVCHI is the best value pick. It measures 105 cm by 45 cm by 160 cm, with a reinforced PE cover, a roll-up door held by clips, four vents and a side pocket. Buyers drop rocks or gravel in the pockets, or bricks on the bottom shelf. The frame falls apart during assembly if the bottom poles are not pressed fully home. The weight field says 200 g, which is not a real packed mass. Skip it if you wanted panels you can bolt to a wall.
The plain Bamworld at about £22.99 is the top pick when the job is seed trays on timber, not a walk-in. Reviewers mention a mallet and gloves in the box, and one calls it a small unit for about six trays that the photo exaggerates. It can blow over unless you pin it. The title says winter-proof; nothing in the file is a winter test. The lit sibling at about £36.99 adds LED strips, including a stated 3,000 K mode and a 660 nm mode, with 4.4 from 61 reviews and only a handful of UK texts here. Those lights are not a heater. Skip the lit version if you only wanted the cheaper rack, and skip both if the 22-inch shelf claim and the 32 cm dimensions field still disagree when you measure your trays.
The about £17.29 DIVCHI, 50 cm by 45 cm by 130 cm, 4.4 from 634 reviews, is the cheapest that still grows seedlings if you stay gentle. The title says steel. A UK reviewer says the parts are plastic, and a bullet names PP connectors. Mesh shelves bend, and the cover tears if you yank the zip. Skip it outdoors in an exposed spot.
Rigid lean-to and the timber cold frame
The Outsunny 6 ft by 4 ft lean-to is the only listing here whose bullets name a galvanised steel base and ground bolts. It is about 192 cm by 127 cm by 214 cm, 17.3 kg, aluminium, with a sliding door, one roof vent and polycarbonate panels, at about £157.69. The star line is 3.6 from 52 reviews. Reviewers describe image-only instructions, a two-person build, missing parts, thin panels they silicone or tape, and houses that lost panels or a roof in wind, including one report of damage after a day they put at about 45 mph even behind a wall. There is no wind-speed rating on the page. Choose it when you have a wall, you will bolt the base, and you accept a fiddly build and a thin review file. Skip it when you wanted to move the house next spring, or when you are treating polycarbonate as a storm guarantee. The plastic versus polycarbonate page holds that trade-off.
SG Traders at about £79.99 is the wooden option that is not a Bamworld rack. It is about 69 cm by 49 cm and 120 cm high, 7 kg, with semi-transparent polycarbonate, three slatted shelves, two front doors and four vents, and 4.2 from 220 reviews. People use it for seedlings and tender plants and often finish assembly in about half an hour. Others say the holes do not line up. One buyer found the panels too opaque and replaced two door panels with clear plastic. The bullets describe hardwood, not a steel base rail. Skip it if you need to stand inside. Weight it. At 7 kg it is still light in a gust.
Common questions
Which is best for a small patio?
If the patio is a strip about 45 cm deep, the extra-wide DIVCHI at 105 cm by 45 cm is the best value fit, provided you weight the pockets. If you only have room for seed trays and want the highest star line, the Bamworld at about £22.99 is the top pick, and you should check the size clash on the page. A 143 cm square VOUNOT needs a square of slabs, not a strip.
Is the narrow or the square VOUNOT the one to buy?
Buy the square at about £44.49 when you have 143 cm each way and want eight shelves. Buy the narrow at about £33.49 when depth is about 73 cm. Both show the same 4.2 from 1,636 reviews in this capture. The square lists two vents and 32 cable ties. The narrow spec line says plastic while the bullets say metal, so read that page twice.
Is the lean-to worth about £158 here?
Only if you want a wall-fixed polycarbonate house with a stated steel base and you have read 3.6 from 52 reviews. Several of those reviews describe storm damage and a hard build. If you want a movable walk-in under £45, the VOUNOT or Outsunny tents are the closer match, with their own zip and anchoring limits.
Do the Bamworld lights change the pick?
They change it if you are growing on a balcony or indoors and want the stated LED modes. They do not make the about £36.99 model a better outdoor greenhouse than the about £22.99 rack, and they are not a heater. The UK text sample in this file is a handful of reviews, against 109 on the unlit listing.
Who should avoid mini tiers?
Avoid them if you need to stand and pot, if you will load heavy ceramic pots onto mesh, or if the site is exposed and you will not weight or pin the base. The about £17.29 DIVCHI is the clearest skip for an open garden, because the steel title does not match the plastic parts reviewers describe.
What is the wooden option if I do not want a cloth tent?
SG Traders at about £79.99, with polycarbonate on hardwood, two doors and four vents, in a footprint about 69 cm by 49 cm. It is a cold frame, not a walk-in, and reviews split between a half-hour build and holes that do not line up. Bamworld is the cheaper timber rack with a PE cover, not rigid panels.
