4ft Wide Greenhouses
Maximise your growing potential in narrow gardens and patios with our compact 4ft wide greenhouses. Designed for alleyways and smaller plots, these models offer the same headroom and features as larger structures without dominating your outdoor space.
We stock freestanding and lean-to options from Elite, Vitavia, and Swallow, available in aluminium or timber. Choose from horticultural glass, toughened safety glass, or polycarbonate glazing to suit your location. Whether you need a simple Vitavia Ida lean-to or a high-spec Elite Compact with double doors, all our 4ft wide models come with Free UK Mainland Delivery.
About Our 4ft Wide Greenhouses
A 4ft wide greenhouse is the answer for a narrow garden. It slips down a side return, along a boundary, or against a fence where a standard 6ft or 8ft house would never fit. We stock 78 models at this width, from £269, in freestanding and lean-to styles from Elite, Vitavia, Access and Swallow.
The trick with a narrow greenhouse is to grow upward. With only 4ft of width you get one staging run and a path, so make the most of the height with cordon tomatoes, climbing beans, or wall-trained crops. A 4ft-wide lean-to against a sunny wall borrows heat from the brick and gives you the longest growing run for the footprint.
Why We Chose This Range
"Narrow gardens are where we fit a lot of these, and the mistake people make is buying short. At 4ft wide you have no room to step back, so headroom is everything: get a model you can stand up in and train plants up, not out. The Elite Windsor is the one I reach for here. The frame is stiff for its width and the door slides rather than swings, which you appreciate when the path is tight."
— Matt, Founder of Greenhouse Stores💡 Tip: Measure the path beside the greenhouse, not just the base. You need room to walk a wheelbarrow past and to open the door fully. On a 4ft-wide run, a sliding door saves the swing space a hinged one steals.
🔧 Matt's Installation Tip: Square the base on a tight plot
A long, narrow base is easy to build out of square, and a 4ft frame shows every millimetre of it in sticking doors. Check both diagonals are equal before the mortar sets, and pack the low corners so the whole run sits dead level.
Matt's Pick: Elite Windsor 4x4 Lean-To
Best For: A narrow plot or a sunny wall with limited depth.
Why I Recommend It: A stiff aluminium frame at a slim width, a space-saving sliding door, and the wall behind it adds warmth for an earlier start.
Price: from £429

Frequently asked questions
What is a 4ft wide greenhouse good for?
It fits narrow gardens and side passages. A 4ft width slots in where a 6ft or 8ft greenhouse cannot, giving you one staging run and a path. Grow upward to make the most of the space.
Can you grow tomatoes in a 4ft wide greenhouse?
Yes, as long as it has the height. Cordon tomatoes grow up a string, so a tall 4ft-wide model holds a productive row. Pinch out side shoots to keep the plants narrow and the path clear.
Is a 4ft lean-to better than a freestanding one?
A lean-to is warmer and saves space. The wall behind it stores heat and shelters the greenhouse, giving an earlier start. A freestanding 4ft model gets even light from all sides but needs an open spot.
Do I need a base for a 4ft wide greenhouse?
Yes, a firm, level, square base. A long narrow frame shows any twist as sticking doors, so a manufacturer base kit on slabs or concrete is worth getting right before assembly.
How much room do I need around it?
Leave a path wide enough to walk and barrow past, plus space to open the door. A sliding door needs no swing room, which helps on a tight 4ft-wide run against a boundary.
