Ridge ventilation

Air circulation starts low down in our greenhouse but hot exhausted air can escape through the handsome full length ridge vents, located on both sides of the greenhouse for optimum air flow. Plants love air movement, you will be rewarded if you offer plenty of fresh air. To this end our vents are automated with heat sensitive cylinders and strong spring mechanisms. 6mm toughened clear glass panels allow maximum light and the openers allow maximum ventilation.

The Complete Aluminium Greenhouse

Contrast the Grey White (RAL9002) polyester powder coated heavy duty aluminium portal frames with the quartz grey (RAL7039) glazing system and you have a modern greenhouse made with traditional skills. Powder coated aluminium is noted for its longevity and resistance to abrasion, just give it an annual face wash and it will remain as good as new. Aluminium is fully recyclable but you don’t need to worry about that since this greenhouse is built to last a lifetime.

Small Greenhouses For Sale UK

Key Facts

  • Our Small Greenhouses are available in as little as 80 x 68 inches (2026mm x 1622mm)
  • High eaves and 45 degree pitched roof to make the most of the space available
  • Equally as strong as our larger greenhouses being made from Accoya Timber portals and with tight fitting safety glass
  • High capacity gutters to help weather any storms
  • Unique Cultivar Greenhouse Ventilation System to aide plant life


It is often difficult to find a small greenhouse which is designed to stand the test of time. Many options tend to flimsy tent pole constructions or made from light weight aluminium with basic fabric covers which would be unlikely to weather a storm.

With Cultivar though, you will get a small greenhouse that ‘the big bad wolf’ would not blow down. We wouldn’t put our name to anything else, with the Cultivar Greenhouses brand being synonymous with ultra high quality and luxury.

Our neat and compact greenhouses come in a width of 6ft 8 inch (2028mm) but offer all of the advantages of our larger greenhouse range. All of our designs come with strong Accoya timber portals, tight fitting toughened safety glass and high capacity gutters to ensure that they can withstand even the toughest of conditions.

Our small greenhouses also measure 5ft 4 inches (1622mm) in length and are designed with the intention of ensuring that even those with the smallest of gardens will have enough room to partake in their favourite hobby of gardening.

Frames

Our unique glasshouse frames

Wide 750mm toughened safety glass panels set into slim aluminium frames give plants the warmth, light and ultraviolet light required for promising propagation. The frames are designed based on modern sophisticated window frame principles but miniaturized to allow more light. The glass rests between EPDM gaskets which allow the glass to expand when it gets hot but makes sure the glass is securely and snugly held in place with no rattles. The framework is powder coated in quartz grey, RAL7039, for a maintenance free finish.

Modern materials

Accoya is not only attractive, maturing to a grey patina, but is long lasting and dimensionally stable. The perfect tongue and groove boarding is machined to our exclusive design as we need consistency of quality and boards that will not warp, twist or bow. Twinned with automated low level ventilation the Plant House is both good looking and talented.

Low level ventilation

Full length even air flow

Automated vents located at the plinth level run the entire length of each side of the greenhouse, providing more than enough ventilation. These automated flaps will provide the very best growing conditions. The autovents react to increased air temperature to ensure that your plants are not exposed to extreme temperatures.

Eaves vents

Frameless and made from toughened safety glass

In the instance that you are building a dwarf wall on which to sit your greenhouse we offer full length eaves ventilation. These run the entire length of both sides of the greenhouse and are operated manually with a simple central opener. Like the roof ventilation these are frameless and made from 6mm toughened safety glass. The edges of the vents are polished and the corners are designed with a radius for safety. Automatic openers can be exchanged for manual openers should you desire.

Staging and shelving

Utility, practicality and versatility

Work benches have never been so thoughtfully designed and have probably never been so strong and versatile. When installed the slatted aluminium surface will support all your plants. You can choose to have the staging down one or both sides depending upon your growing plans. If you would like a softer surface then our aluminium slats can be replaced by Accoya, an aesthetically pleasing, strong and reliable alternative. If you would like a sand bed or pea gravel then that’s no problem, just call us to discuss your needs. You can also buy online a ABS Plastic Tray for the 8 and 10 foot wide models which can be used for potting up or to soak your pots.

There is also a hidden advantage, your staging can be folded down, just remove the tray and it will pivot down in a flash with the external frame. If you prefer you can unhook the staging for complete removal. This will create a space should you wish to grow tomatoes during the summer months. The shelves adopts a similar range of options and facility.

The practical and attractive framework is finished in quartz grey, RAL7039, to co-ordinate with the greenhouse.

Accoya is obtained from fast growing sustainable sources including FSC, it is treated with natural occurring acetic acid which modifies the core producing a hard, dimensionally stable, beautiful solid wood, exceeding the qualities of tropical hardwoods.

The ultimate greenhouse door

Tight Fitting, Soft Closing with Sensible Handles, Locks, Hinges and Hold Backs

Door jammed or loose on it’s runners ? Not with a Cultivar Door. This class beating door wide enough for a wheelbarrow and on the 8 and 10ft models good for wheelchair access with a low threshold. It’s solid aluminium frame elegantly sits within a wooden Accoya framework. Glazed uppermost with toughened safety glass whilst the lower section has heavy duty Accoya wood paneling, it’s designed for a lifetime of hard work.

Not your typical greenhouse door, this one is secure, a high specification Eurolock (with spare keys), a quality handle, inside and out, hinges that will comfortably carry the weight of the door opening to 180 degrees where a push action will keep the door secured back and a pull will release when the day is done.

Safety glass throughout

Clearly the best

Forget delicate 2mm horticultural glass, broken storm damaged panes. Other than boulders there is not much that will break our 4mm toughened safety glass. Captured securely our strong frames and rigid construction will further protect the glass. Like all safety glass it will not shatter into shards but into small crystals which can be swept up. In any case it’s a one in a million chance but easily remedied by a simple replacement method. Designed to last a lifetime 4mm or 6mm toughened safety glass to British Standards is used throughout a Cultivar Greenhouse.

Small details make a big difference

All our roof and wall glazing frames have a groove, seen as a shadow line, known in the trade as a screw port. This has been designed with the grower in mind so you can fix, tie and hang plants or tools securely in position. No drilling required.

Our video shows just how easy this is using two proprietary fixings which can be bought online from the likes of amazon or ebay. A little creative thinking may suggest other solutions and uses. For instance, a simple screw with twine around the head would hold up your tomatoes or your electrician may use P-clips screwed into the groove to route your wiring.

The most important piece of information is however here. The screws should be stainless steel, self tapping, 4.2mm (no.8) gauge. The depth of the groove is 8mm, it cannot be tightened beyond this. A variety of screws may be required to suit your plans.

Build a base

Matching or contrasting

The traditional dwarf wall greenhouse can be given a new look for the new century. Glazed bricks in a wide choice of colours would create quite a stir if you chose to contrast your new pastime and hobby centre to the appearance of your home. Brick bases can be a sensible but long term choice for the enthusiastic gardener, a sign of serious intent.

Furthermore brick wall greenhouses give a more even temperature throughout the structure, they’re slower to heat up and slower to cool. If you are seeking this option then discuss with your builder the plans for your new greenhouse base.
