Which Alton Greenhouse Is Right for You?

  • Best garden showpiece: Octagonal — eight-sided with a cupola and double doors.
  • Greenhouse + potting shed in one: Fusion — glass growing side and cedar shed side with a floor.
  • Best classic cedar greenhouse: Cheltenham — half cedar walls, extra tall 10' peak, four lengths.
  • Orangerie for a smaller yard: Durham — T-shaped with an entry foyer.
  • Grand orangerie: Cambridge — Alton's largest T-shaped orangerie.

Special-Order Any Alton Model

The models above are Alton's US range, but we can special-order any greenhouse in Alton's full UK range through Exaco, Alton's US importer — including the Evolution series (Evolution Six, Eight and Twelve, up to 12'9" wide), the Amateur, and Victorian styles such as the Ewell, Harrow, Denstone and Oakham. Tell us the model and size you want and we'll get US pricing and lead time. Call or text 732-806-7959.

Why Cedar?

Cedar insulates better than aluminum (about R-1.35), so an Alton greenhouse holds temperature and humidity more evenly — and it smells wonderful. The aluminum base keeps the wood off the ground and the bar capping seals the glass, so the cedar lasts with little upkeep. Comparing materials? See our Janssens glass greenhouses, all wooden greenhouses, or our Janssens vs. Alton vs. Hoklartherm buying guide.

FAQ

Where can I buy Alton cedar greenhouses?

World of Greenhouses is an authorized Alton dealer carrying the full US Alton line — Octagonal, Fusion, Cheltenham, Durham, Cambridge, Lancing and Westminster — with free shipping, financing and installer coordination. Call or text 732-806-7959.

Who makes Alton greenhouses?

Alton is a British cedar greenhouse maker that has built greenhouses in the UK since 1921. Exaco imports them to the US, and World of Greenhouses is an authorized Alton dealer.

How strong is it in wind and snow?

Alton greenhouses don't carry a US wind rating or code certification. In a sandbag load test, an Alton greenhouse roof held about 900 kg (roughly 2,000 lb) of sandbags. The steep 45° roof sheds snow well. Exaco recommends them for backyards with some shelter from nearby homes, fences or trees rather than wide-open, very windy sites — tell us about your site and we'll help you decide.

What's the difference between the Westminster and the Lancing?

Same size and shape (10'9" wide, 11'1" peak, 179–224 sq. ft.). The Westminster has half-height cedar walls below the glass for a classic look and extra insulation at bench level; the Lancing is glass to the ground for maximum light.

What options can be added?

Staging and shelving, Victorian cresting, extra automatic roof vents, louvre side vents with automatic openers, a second door, internal shade blinds and hanging-basket brackets. Some options vary in the US — call or text us and we'll check with Exaco.

How are Alton greenhouses delivered and assembled?

Free freight shipping to most of the contiguous US, direct from the US distributor by truck (someone must be there to receive it). Doors and windows come pre-assembled; plan on roughly 2–3 days for 2–3 handy people, or we coordinate an installer.

What foundation does it need?

A level, square concrete slab or concrete piers/footings. Exaco ships US Alton greenhouses with anchors to embed in concrete — pavers alone, as shown in Alton's UK manuals, aren't enough for US weather. We'll help you plan the base and anchoring for your site.

Can Alton greenhouses be built in custom sizes or special-ordered?

No — Alton greenhouses aren't made to custom sizes, and Alton doesn't make a 20'-wide model. But we can special-order any model and size in Alton's full UK range, not just the ones listed here. For a custom size or anything wider, see our custom Janssens glass greenhouses, which can be built up to 20' wide.

Cedar or aluminum — which is better?

Cedar insulates better (about R-1.35) and holds temperature more evenly, and it gives a warm, traditional look. Aluminum-framed glass greenhouses like Janssens carry published wind and snow ratings and need less upkeep.

What warranty does it have?

A 10-year warranty on the cedar framework.
