The 6ft wide 6x18 Elite Kensington Lean to greenhouse is a quality lean-to made right here in Britain. Customise the Kensington with the many options available with this greenhouse, from different colour finishes to various staging and shelving options available below.

The Elite Kensington 6ft x 18ft lean-to will give you plenty of space to bring on seedlings and grow salad, herbs and vegetables all year round as well as being a pleasant place to relax. The door on the Kensington can be fitted on either end of the greenhouse or even in the middle, making it easy to fit in with the space you have.

The 6mm twin wall polycarbonate glazing gives awesome insulation as the panels have silvered edges meaning that they are completely sealed. Because they are sealed they will not fog up inside with condensation. Of course polycarbonate is the safest glazing of all and is ideal for family gardens, schools and nurseries where children are running around. We recommend adding the optional Elite Bar Capping to polycarbonate glazed greenhouses as it further windproofs the greenhouse by holding the polycarbonate firmly in the frame.

This Kensington 6 x 18 has 3 opening roof vents and 1 louvre window vent for ventilation, a smooth single sliding door and integral gutters to collect rain water.

Elite Integral Gutters
5 Slat Diamond Staging

The Diamond shelving and staging are designed for Elite greenhouses. They are durable, long-lasting, and supported by cantilever bracing, eliminating the need for legs. This design provides space underneath for growing plants, storing pots, and wheelchair accessibility. Both can be color-coded to match your greenhouse.

Elite Integral Gutters
Elite Integral Gutters

You’ll find proper gutters on Elite greenhouses rather than narrow channels. These are more effective at gathering up rainwater for your water butt and less likely to get blocked up with leaves.

Elite Greenhouse
Elite Greenhouses

Elite Greenhouses have been made right here in the UK by the same family-run business for the last 60 Years. Using some of the strongest Aluminium profiles available, a wide range of Powder Coated Finishes as well as smart touches like Low Threshold Doors, innovative Glazing Bar Capping and Stainless Steel fixings throughout, you'd be hard-pressed to find better greenhouse anywhere!.

Elite Greenhouse 10 Year Warranty
10 Year Warranty

Elite greenhouses come with a 10-year warranty on the greenhouse frame. This warranty covers any manufacturing defects in materials or workmanship. However, it does not cover glass, polycarbonate or Wind Damage. The warranty is only valid if the greenhouse is assembled according to the provided instructions

Elite Kensington 6x20 Lean to Greenhouse Horticultural Glazing
Purchased the greenhouse from Garden Buildings Woodcote Green Ltd in September 2015. Good quality greenhouse at a good competitive price. The service I received from the people at Woodcote was excellent and the delivery was good as well, and the delivery driver called to let me know his approximate ETA. The instructions were a bit vague or incorrect in places and would have baffled some who have limited DIY skills, but I followed some tips given to me by Woodcote and it worked out ok. I was a few glass clips missing but Woodcote supplied them to me from their spares free of charge. After I had put the glass in I noticed that two of the large panes had imperfections in them so I took photos and showed them to Woodcote and they called Elite straight away. Someone from Elite rang me to discuss the problem and the replacement panes arrived the following day. The service that I received from both Woodcote and Elite was excellent and this kind of service you cannot get ordering online, sometimes face to face is best.

How to Prepare the Ground for a Greenhouse Base

How to Prepare the Ground for a Greenhouse Base

A solid base is the backbone of any greenhouse. You might think skipping this step saves time, but trust me—I've seen plenty of greenhouses fail because of poor foundations. A dodgy base causes more headaches than you'd believe.

What happens with a bad base? Glass cracks. Doors jam. The structure twists. Water pools where it shouldn't. And fixing these problems costs way more than doing it right first time.

Best Position for a Greenhouse UK

Best Position for a Greenhouse UK

Placing your greenhouse in the right spot makes all the difference between thriving plants and disappointing results. As a greenhouse specialist who's spent 15 years helping UK gardeners optimise their growing spaces, I've seen first-hand how position affects everything from temperature regulation to plant health.

Let me share what actually works in our unique British climate. The greenhouse position might seem like a minor detail, but it's one of those things that can make or break your growing success. I made this mistake myself when I first started - my poorly positioned greenhouse meant I was fighting an uphill battle with inadequate light and temperature fluctuations.
