As with all foundations, it is very important that greenhouse foundations are completely flat, level and square.
Given that a low threshold door is now standard on most models, installing directly onto soil isn’t favourable. Soil or grit will fill up the door track and interfere with the smooth operation of the doors. On larger/heavier models, you also face the risk of the corner anchors subsiding and causing further problems.
Our advice is to opt for one of the foundation options below.
Types of Greenhouse Foundations
Remember, most greenhouses are larger than the quoted ‘nominal size’ (ie: 6ft x 8ft) therefore ensure you have the correct external dimensions before preparing a suitable base.
Solid concrete foundation
Solid concrete greenhouse foundations are simple and strong. We use timber shuttering with wet poured concrete to a chosen size, and finish using a power float/screed. This provides a completely smooth finish with minimal drainage which is easy to sweep clean. A return visit is required to remove shuttering and for installation of the greenhouse and is also recommended for sheds, summerhouses and garages.
Solid slabbed base
Using smooth, textured (not riven) slabs, this provides a smooth and clean area, that is slightly more decorative than concrete. Some drainage is achieved through the joints in the slabs which are laid on a level bed of sand and cement (not just sand!). Greenhouse installation can be completed within the same day (depending on size). Usually more expensive than concrete due to the additional cost of the slabs.
Outline base
Using 6″ wide concrete edgings, bedded onto a sand and cement mix, we can create a precision footing for the greenhouse to be sited on and secured to. This leaves plenty of options for internal ground cover (gravel/bark chipping etc). Greenhouse installation can be completed within the same day (depending on size).
Combination base
As the name suggests, a combination of both an outline base and slabbed path, allowing for a mix of working areas and gravel/bark chipping ground covering. This provides lots of drainage and flexibility. Greenhouse installation can be completed within the same day (depending on size).
Decorative foundations
If you’re looking for something a little more decorative, you may like to consider a dwarf wall, quarry tiled base or brick sets/pamments. We are happy to discuss any specific requirements you may have to create a fully bespoke greenhouse foundation as part of our ground-up installation service.
Your Questions About Greenhouse Pro Answered
What types of greenhouses do you offer?
We supply a wide range of greenhouses, including compact starter models, budget-friendly options, large aluminium or timber designs, and bespoke builds. While primarily for domestic garden use, our greenhouses are also suitable for display areas for garden centres, outdoor spaces, and dining areas for venues. We also offer a full range of accessories to complete your growing space.
Do you offer advice for first-time greenhouse owners?
Yes, we’d love to help you start your greenhouse gardening journey! From selecting the right greenhouse and position in the garden, to choosing essential accessories and installation options, we provide honest, non-sales-driven, tailored advice every step of the way.
Do you deliver greenhouses across the UK?
Yes! While our family-run business is based in East Anglia, we supply and deliver greenhouses nationwide via our manufacturers, trusted delivery partners, and sometimes ourselves. Whether you’re in London, Scotland, or Cornwall, we can get your greenhouse to your garden safely and efficiently.
Why should my greenhouse be delivered to you?
Having your greenhouse delivered to us first saves you handling the delivery and needing dry, secure storage. We unpack everything, check for damage or missing parts and consolidate packaging for your recycling.
We also pre-assemble your greenhouse in our workshop, constructing the gable ends, sides, doors and vents so it arrives partly assembled. Working flexibly in the evenings, at weekends or in poor weather results in a faster, smoother on-site installation. This approach is rare in the UK and is what sets the Greenhouse Pro service apart.
Can you install my greenhouse?
Absolutely. We offer professional installation services for all greenhouses that we supply within the East Anglian area, with the possibility of installation further afield depending on the specifications. We’ve successfully installed in locations as far afield as Scotland, London, and Cornwall.
What is the lead time for delivery and installation?
Lead times vary depending on the manufacturer, size, and type of greenhouse. We provide a clear estimate at the time of order and keep you updated throughout the process. As a general guide, 6–8 weeks is typical for most of the year, although some orders can take 12–14 weeks.
What type of base do you recommend?
We highly recommend either a solid slab/concrete base or an outline footing. It’s important that your greenhouse sits level and square so it can be securely fastened to the base. Please note that quoted greenhouse sizes are often nominal, meaning they may be slightly larger than, for example, 6ft x 8ft. If needed, we can provide local* foundation services to ensure a perfect fit. For more details, please see our Foundation page.
