Greenhouse Buying FAQs
Here are some of the most common questions we’re asked by customers who are choosing a greenhouse for their garden, allotment or patio.
1. What type of greenhouse should I buy?
The best greenhouse for you depends on your garden space, budget, preferred style and what you want to grow. From our experience, aluminium greenhouses are a popular choice for gardeners who want a practical, low-maintenance option, while wooden greenhouses are often chosen for their traditional appearance and natural warmth. Lean-to greenhouses are ideal for placing against a wall, and compact wall gardens or cold frames work well when space is limited.
2. What size greenhouse is best for a beginner?
For many first-time growers, a 6ft wide greenhouse is a practical starting point because it offers enough room for seedlings, tomatoes, herbs and staging without overwhelming a smaller garden. If you have more space, an 8ft wide model gives you a more comfortable walkway and extra growing room on both sides. We often find that customers fill their greenhouse quickly, so it is worth choosing the largest size your garden and budget can comfortably allow.
3. Is it better to choose a freestanding or lean-to greenhouse?
A freestanding greenhouse is a good choice if you have an open, sunny part of the garden and want access around all sides. A lean-to greenhouse is better suited to patios, courtyards and smaller gardens, as it sits neatly against a wall and can benefit from the warmth of the building behind it. If space is tight, a lean-to or wall garden can give you a productive growing area without taking over the garden.
4. Where should I put a greenhouse in my garden?
The best position for a greenhouse is usually a level, sunny and sheltered spot with easy access to the door, vents and water supply. Try to avoid heavy shade from trees, fences or buildings, as plants need good light to grow well. A sheltered position can also help protect the greenhouse from strong winds, while leaving space around the structure makes cleaning, glazing checks and general maintenance much easier.
5. Do greenhouses need a base?
Yes, we would always recommend installing a greenhouse on a firm, level and secure base. A good base helps keep the frame square, improves stability and can make the greenhouse easier to assemble. Depending on the model, suitable base options may include concrete, paving slabs, a brick plinth or a dedicated metal base. Getting the base right at the start helps protect your greenhouse and keeps doors, vents and glazing working as they should.
6. What glazing should I choose for a greenhouse?
The right glazing depends on your budget, garden and how you plan to use the greenhouse. Horticultural glass is often the most affordable option, toughened safety glass is stronger and safer if broken, while polycarbonate glazing is lightweight and impact-resistant. From our experience, toughened glass is a popular upgrade for many home gardeners, especially where safety, durability and a smarter finish are important.
7. Can I use a greenhouse all year round?
Yes, a greenhouse can be used throughout the year with the right setup. In spring, it is useful for sowing seeds and raising young plants. In summer, it creates a warm space for tomatoes, cucumbers, peppers and tender crops. In autumn and winter, it can help protect plants from frost, rain and wind. Accessories such as staging, shading, ventilation, insulation and heating can make the space more comfortable for both plants and gardeners.
8. What can I grow in a greenhouse?
A greenhouse can be used to grow a wide range of plants, including tomatoes, cucumbers, peppers, chillies, lettuce, herbs, strawberries, flowers and tender ornamentals. Many customers use their greenhouse to start seedlings earlier in the season, grow crops that need extra warmth, or overwinter delicate plants. The best choices will depend on the size of your greenhouse, the time of year and whether you add heating, shading or ventilation. Read more in our blog post about exploring the benefits of growing your own vegetables versus buying them from a supermarket.
9. Do I need planning permission for a greenhouse?
Most domestic greenhouses in the UK do not need planning permission, but there can be exceptions. It is worth checking before you buy if you live in a listed property, conservation area, national park or if the greenhouse will be very large, close to a boundary or positioned in front of the house. Your local planning authority can confirm what applies to your property.
10. Why buy a greenhouse from GardenSite?
From our experience helping UK gardeners since 1999, choosing the right greenhouse is much easier when you can compare trusted brands, sizes, materials and accessories in one place. At GardenSite, we offer a wide range of aluminium, wooden, lean-to and compact greenhouses, along with expert advice by phone, secure online ordering, nationwide delivery and a Birmingham show site where selected greenhouse models can be viewed in person.
11. Should you buy a greenhouse online?
You may have already searched online for a local greenhouse shop or for 'greenhouses near me' in order to support a business within your area. Because greenhouses are large, bulky products, many retailers are unable to display a wide range of models in person, which means customers often compare and buy them online. If you're local to us in Birmingham, you're welcome to visit our greenhouse show site, otherwise you may be restricted to shopping for a greenhouse online. But not to fear, shopping online, even for something as large as a greenhouse is fast becoming normality, and there are several benefits to buying a greenhouse online versus in a brick and mortar store.
Here's why we think it's better for our customers to shop for a new greenhouse online over a brick and mortar store:
- Better prices! You can more easily shop around for the best price and compare greenhouse models. And as there's less costs involved for the retailer (no need to rent shop floor space etc), those savings are usually passed onto the customer.
- Better choice! Online greenhouse stores can offer more brands, sizes, models and greenhouse varieties compared to the limitations of a brick and mortar shop. With greenhouse brands being sourced from across the UK and worldwide to offer the best and largest range to gardeners.
- Better quality! Reputable online greenhouse sellers like ourselves only offer for sale greenhouses that we know and trust, having had long relationships with the manufacturer's behind the brands, and having tested and experienced each greenhouse in person.
- Shop in comfort! You can shop for a greenhouse online in the comfort of your own home. Taking all the time you need to browse, compare and pick out the perfect greenhouse model for you and your garden. Our secure website is online 24/7 so you're not limited by opening times.
12. Can I replace my existing shed with a greenhouse and use that for both storage and growing?
Yes! If your garden only has space for one structure, you may be thinking that you don't have the room to accommodate a greenhouse if you already have a shed. However, that's where greenhouse combi sheds come into play. Potting sheds are also another name for these, and they offer a place to both grow and store in, giving a structure that combines both a shed and a greenhouse in one.
Combi sheds and potting sheds come in all different sizes and variations. Some can be ordered as a 50/50 split, others come with larger greenhouse partitions with smaller storage space, others comes with bigger shed partitions and smaller growing space - it all depends on whether you'd like more storage or a bigger greenhouse area. You can browse our range of potting sheds here.
