Product Code: ELI-KEN4-20
The Elite Kensington 20ft long lean to greenhouse is the largest in the 4ft wide range, built from high quality aluminium that will not rust, warp or rot.
It's an exceptionally rigid frame, maintenance free, that you can personalise into a bespoke structure using Elite's exceptional list of optional accessories.
First of all, choose a colour for the frame. The alternatives start at milled aluminium and in addition there are several different coloured powder coatings, you certainly won't be limited to the usual green or silver.
Then you must decide on the number of entry points that are needed. Single doors can be installed at one or both gable ends, and further smooth sliding doors may be located at the front of the greenhouse. The latter can be double, so dramatically increasing accessibility.
Summer heat can increase the temperature inside a greenhouse to heights that are detrimental to plants. So three roof vents and a louvre are already fitted. You can choose to install more vents to draw in cooling air and also to have automatic openers, so that when you are away from home temperature and humidity are kept at acceptable levels.
If the lean to is positioned so that you can access it straight from the house, you must install toughened glass. Otherwise you have the alternatives of horticultural or polycarbonate glazing. Bar capping, the same colour as the frame, can be fitted to improve the greenhouse's appearance and further secure the glazing.
With so much space to grow a large selection of plants, shelving and staging in addition to the standard aluminiul extruded shelf is essential. You'll find lots to choose from on the list of accessories, different widths and configurations that will be so useful in such a productive growing area.
The heavy duty durable gutter not only provides extra strength for the greenhouse, the rainwater that's collected can be channeled into a butt by the popular rainwater collection kit, ready to be recycled. Plants really do prefer it to tap water.
Finally, you must remember that a base is always required. This can be handbuilt with bricks or slabs but probably the best solution is to buy an Elite base that is specifically designed for the job and can be the same colour as the frame.
Please note that the photographs illustrate various Kensington greenhouses and show both standard features that are listed below and optional accessories that can be purchased separately.

Select Your Options
Option 1 > Choose Your Frame Colour
Please select from the following ten frame colours. Milled Silver aluminium is pre-selected by default and is the standard option. However, powder coated frame options are also available at an additional cost.
Option 2 > Choose Your Greenhouse Glass
We offer three different types of glazing: 3mm Horticultural Glass which is pre-selected by default, but you can upgrade to single sheet Toughened Glass or 6mm Polycarbonate Glazing here.
As Horticultural Glass is included in your frame price it is a NO COST option. The additional cost of Toughened Glass or Polycarbonate Glazing is indicated below.
Please Note: Greenhouse glass images below are for guidance only.
Option 3 > Do I Need a Base?
Yes, quite simply you do. Greenhouse frames need to lip over a base (or upstand) which also allows the door to lip under the frame. The base also gives you the required height needed inside your greenhouse. Without a base your greenhouse would be 5ins too low.
Preformed Alloy Bases are available in either milled silver aluminium or powder coated to match your chosen frame colour. All Elite Supreme Bases come complete with a drop door option which gives a low threshold. Alternatively, you can build a brick base but you will need to be accurate with your measurements.
Option 4 > Bar Capping?
Bar capping is a continuous strip glazing system used instead of glazing clips, this gives a far neater streamlined appearance. It's made from PVC and is UVI treated.
Please Note: Bar Capping is NOT suitable for use with horticultural glass. But is recommended for use with single sheet toughened and polycarbonate glazing.
Option 5 > Where would you like your door positioning?
A Single Door comes as standard and there is the option to upgrage to Double Doors however Double Doors cannot be fitted in the gable ends of a Kensington 4 or 6.
Please select from the options below where you would like your door positioning?
Option 6 > Internal Partition with Single Door?
Would you like an Internal Partition? This option enables you to divide your greenhouse into 2 sections. This is ideal where you wish to create areas or zones for plants with differing needs.
Available in milled silver aluminium or powder coated coloured finish, complete with integral base and single door. You can also choose to have Bar Capping and all the glazing options are available.
If you choose an Internal Partition you will need to check 1 of the first 3 boxes below. You then add to your initial choice by checking any other appropriate boxes. You may have to check up to 4 check boxes. This is a complex option so please choose carefully!
We will contact to you to determine the final positioning of you partition.
