best greenhouses - modern gardens

If you're getting your green fingers stuck into growing new plants, herbs, and produce in your summer planters, the likelihood is that a greenhouse may have crossed your mind at some point.

These houses - typically made of glass and wood or steel - are like a warm cosy blanket for your greenery, giving them enough light and warmth to grow without facing the tough UV rays or unpredictable British weather. Especially when it comes to those frosty winter months, these greenhouses can be a saviour to all us gardeners.

The thing is though, there are so many choices of greenhouses out there. You can get one that is huge and barn-like or one tiny enough to fit a few plants. Which one's the best for you? Well, we've covered everything in our greenhouse guide below - including the best greenhouses you can buy right now.

What type of greenhouse should I get?

There are lots of elements to factor in when you want to start looking for a greenhouse. What size can you fit in your garden? How much can you afford? Do you want a static greenhouse or one that's easily covered and uncovered?

With all of this in mind, there are a few different types of greenhouses you should look towards.

Wooden or steel bases: Whereas steel bases are much easier to put together, wooden frames for greenhouses can look more traditional and may be a more stylish choice - this will make them more expensive, though.

Plastic-covered: Want ease and a cheaper choice? Plastic covered greenhouses are a great option that often has zippers and are easily removed for a lower price.

Shape: You'll have to think about the shape and size of your greenhouse. You can get traditional gable greenhouses easily, but lean-to options are often smaller and just as effective if you have a smaller garden. Then you have arching, cathedral and barn greenhouses too, just to name a few. This all depends on what you're looking for in your greenhouse.

How much to spend on a greenhouse?

This all depends on what materials you want, how many features you want and the choice of size for your greenhouse.

Greenhouses can start anywhere from £30 to over £10,000 depending on what you buy and design, so there's a lot to think about.

For instance, plastic, steel, and wooden frames can be cheaper if they're smaller in size, but they may not be as sturdy if you buy them so cheaply. On the other hand, you can spend lots of money on a specially-designed greenhouse with doors and windows, but you may find this isn't necessary for your budget.

We're all about the value you get for your money, so you'll want to do full research into what you're buying before you get it.

Where can I buy a greenhouse?

Lots of garden centres and outdoor shops will have a great range of greenhouses. Of course, you can also get a great selection easily on Amazon.

If you're looking for your greenhouse we recommend choosing a classic trusted shop like B&Q or Wickes. John Lewis also comes in handy for more expensive greenhouses that can be built for you and Aldi has some more affordable options as part of their garden special buys. We've hunted down the best choices from all these sites below.

Consumer review: "Bought this 6 months ago ... after a busy growing season, I've been very happy with this - it's slimline but fits plenty of seed trays (although I've sacrificed the ground shelf to a heavy bag of compost, as these type of cold frames are prone to blowing over in the wind). The zip still works perfectly, joints have stayed intact, the item feels sturdy enough for the price. It also looks prettier than my other cold frames. A good buy."
