FAQs

Do you need planning permission for a greenhouse?

Depending on your local authority, you shouldn’t need planning permission as long as the greenhouse meets the permitted development rules. Just keep in mind that you'll probably need a permit if it takes up more than half of your backyard or if it's taller than 4 metres.

Which is better: polycarbonate or glass greenhouse?

When it comes to greenhouses, polycarbonate is definitely up there! They are strong and practically shatterproof, perfect for areas with unpredictable weather or where the kids are playing football. Not only that, polycarbonate lets in more light than glass, and they do a good job of retaining heat when the temperature drops.

Should a greenhouse be in the sun or shade?

Putting your greenhouse in a sunny spot is the way to go! That way, the plants get six hours of direct sunlight. Placing the greenhouse under a shade risks damage from falling tree branches.

Is a green or clear greenhouse better?

Both green and clear greenhouses have their own perks—it all depends on what you're aiming for in your gardening needs. A green greenhouse filters out intense sunlight, which can be a lifesaver for sun-sensitive crops in sunny areas. On the other hand, a clear greenhouse lets in maximum sunlight, perfect for those plants that thrive on plenty of sunshine.

What not to put in a greenhouse?

Giant trees, shrubs, and aggressive plants tend to outgrow their spaces; avoid them. Avoid water-hungry crops that may leave a soggy mess, leading to root rot or mould in other plants. Crops known for attracting pests and diseases should be avoided to maintain a controlled environment.

What is the best colour for a greenhouse?

Natural colours like greens and stone shades, such as grey, can really blend in beautifully with your garden. You can even opt for bright white colours if that's your style. Just keep in mind that some colours might slow growth since they can reduce the intensity of light reaching the crops.
