Types of Large Greenhouses
Here are the most popular types of large greenhouse we offer:
Large Lean To Greenhouses
If you have a long but narrower space for your greenhouse, then a large lean to is perfect.
They can maximise the efficiency by using the heat of the building they're leant against, or simply used against a wall.
Large Aluminium Greenhouses
Aluminium greenhouses are lightweight, weatherproof options for your garden or allotment, offering lots of flexibility in style, size, and colour.
Here are some popular greenhouses that come with an aluminium frame (powder coated versions offer colour customisation):
- Eden Bourton Range (10ft Wide, 12ft - 20ft in Length)
Large Wooden Greenhouses
For a traditional greenhouse, you can't get much better than a wooden frame.
These are timeless, blending in perfectly with a natural setting.
Some of our larger wooden greenhouses are the 8ft Swallow Victorian Eagle, and the Clearview Cambridgeshire Potting Sheds, but we also stock very large products like the 13ft Wide Falcon, or the T-shaped Swallow Swaon Wooden Orangery, and the Swallow Mallard ranges.
Large Freestanding Greenhouses
A large freestanding greenhouse is simple a greenhouse that isn't a lean-to, so most of the range above would be considered freestanding.
Large Polycarbonate Greenhouses
A large polycarbonate greenhouse is simply a large greenhouse that uses polycarbonate glazing, and we have this option on all of our products - simply select it from the glazing options on the product page.
Polycarbonate glazing is the safest choice, as it cannot shatter into dangerous pieces.
This is also known as a plastic greenhouse.
Large Dwarf Wall Greenhouses
Dwarf Wall Greenhouses are the type with the brick wall around the edge that adds a unique and sturdy quality to them.

What is a Large Greenhouse?
A large greenhouse (or glasshouse) is considered to be any greenhouse that's over 8ft x 8ft, but tends to be greenhouses in the 10ft+ width range. The frame can be made from aluminium or wood, and the glazing can be toughened glass, polycarbonate glazing, or horticultural glass.
They are the perfect greenhouse when you have plenty of space in a large garden and need a larger growing area. They can have extra width to make a very wide greenhouse, or extra length to create a long and narrow greenhouse. Ideal for growing a large amount of vegetables like tomato and cucumber plants.
How much does a large greenhouse cost?
A 10ft wide large aluminium greenhouse from Elite can start at around £695, whilst the top end of 13ft Wide Swallow Large Wooden Greenhouses can reach around £15,000 (at the maximum length of 37ft).
Here are the glazing options you have with our large greenhouses, which you can choose on each product page:
Toughened safety glass is by far the most popular choice, because it offers the traditional appearance, the clear nature of glass, and it's far safer than the weaker horticultural glass in case of accidents.
Horticultural glass is for when you're on a budget, and you don't expect common accidents to occur that may damage the glass. It shatters into dangerous pieces, so a lot of care and attention is needed.
Polycarbonate glazing is the safest option you can choose, as plastic will not shatter into dangerous shards. There is a downside however, as the clarity of polycarbonate is not great. It's also not recommended in very exposed areas.
Here are the accessories that you can either add to your product or buy separately.
It's especially important to ventilate a large greenhouse, and you have the option to add extra roof windows, auto vents, and other ventilation controls.
Heating is important during the cold months, and heating a larger area is expensive, so make sure you also pair it with proper insulation.

Here are a small selection of the thousands of reviews we've had:
David, 20th July 2020, reviewed the Swallow 6'-7 x 10'-5 Starling Lower Roof Lean To
"Great quality greenhouse and put up very carefully. Excellent job!"
Kathryn, 2nd July 2020, reviewed the 6x12 Elite Dwarf Wall Thyme Painted Finish
"Firstly my thanks to Adrian at SW Greenhouses who answered my many questions and helped me to ensure I choose the right specification. Polite, friendly and professional - customer service at its best. The greenhouse is top quality, a sturdy and aesthetically pleasing structure that adds to the gardens interest rather than being one of those that people try to hide behind a hedge or trellis. Elite contacted me to arrange delivery and this went smoothly. It wasn't the easiest to erect and the instructions were not particularly intuitive, however allow double the time you anticipate or pay for a professional installation! I would highly recommend SW Greenhouses and Elite. Thank you."
John, 6th November 2015, reviewed the 8 x 10 Halls Silver Aluminium Universal With Base
"This is a wonderful Greenhouse, very competitively priced, slightly bigger than advertised dimensions .. which is great. This Greenhouse is very tall, so ideal for tomatoes, cucumbers and even vines. I took delivery in October, so just have some cuttings and winter seedlings in at present, but very much looking forward to next Spring."
