About Our Balcony Greenhouses
You do not need a garden to grow under glass. A balcony greenhouse gives herbs, salad and tender plants the shelter and warmth they need on a flat or apartment balcony. We stock compact models from £219, in wall-mounted lean-to and slim freestanding styles, including mini greenhouses and growhouses from Access, Elite, Juliana and Vitavia.
Two things catch people out up here: how little floor you have, and how much harder the wind blows. A wall-mounted lean-to solves the first, tucking flat against the building and using next to no floor. The wind you beat with sensible glazing, toughened or polycarbonate rather than loose panes, and by bolting the frame down so a gust has nothing to grab.
Why We Chose This Range
"Balconies are exposed places, higher up and windier than a back garden, so I am fussy about what we list for them. I steer people to the wall-mounted Access lean-to types: they bolt back to the wall, use the depth of a windowsill rather than the floor, and the toughened glazing means nothing shatters onto the flat below. A free-standing mini greenhouse works too, but only if you can weigh it down or strap it to the rail."
— Matt, Founder of Greenhouse Stores💡 Tip: Grow upward on a balcony. A tall, narrow lean-to with shelves gives you several growing levels in the footprint of a doormat, so you can raise herbs, salad leaves and a tomato plant or two without losing your sitting space.
🔧 Matt's Installation Tip: Anchor it, always
This is the one job people skip and later regret. A balcony funnels the wind, so fix a wall-mounted model back into solid masonry rather than trusting the rail, and weight or strap a freestanding one. A two-minute check of the bolts each spring saves a smashed greenhouse on the patio below.
Matt's Pick: Access Westminster Mini Lean-To
Best For: A wall or rail on a compact balcony.
Why I Recommend It: It bolts flat to the wall, uses next to no floor space, and the toughened glazing is safe to use up high.
Price: from £324
Frequently asked questions
Can you put a greenhouse on a balcony?
You can, as long as it is compact and firmly anchored. The wall-mounted lean-to types work best because they lean on the wall instead of eating your floor. The non-negotiable bit is fixing or weighting it so the wind cannot shift it.
What can I grow in a balcony greenhouse?
More than you would think. Herbs and salad leaves do brilliantly, and a chilli or a single cordon tomato will crop happily if the balcony gets sun. Stack it on shelves and a tiny footprint goes a long way.
Are balcony greenhouses safe high up?
They are when glazed in toughened glass or polycarbonate and anchored properly. Avoid loose horticultural panes at height, and fix the frame to solid masonry so nothing can blow loose.
How do I stop a balcony greenhouse blowing over?
Anchor it properly. A wall-mounted unit should bolt back into the masonry; a freestanding one wants strapping to the rail or weighting at the base. The wind up there is fiercer than at ground level, so give the fixings a look each spring.
Do balcony greenhouses need much light?
A sunny aspect helps a lot. South or west-facing balconies grow the widest range, but even a shadier north-facing one will keep you in herbs and salad leaves, which are far less fussy about sun than tomatoes.
