We are manufacturers, designers and installers of high specification commercial greenhouses, and our commercial customers can choose the specifications of design they require depending on their individual growing needs.


Full project management is standard, from the initial concept and design process through to completion of installation.


At Keder Greenhouse, we will not be beaten on our level of customer care.

The quality of all materials used in the Keder construction process is the best available. We believe that the best quality equates to longevity and durability.

The Keder Greenhouse system has been specifically designed to be installed with ease and speed, not only in the original installation process but at a later date should any alterations be required.

Please note, as all commercial builds are based on individual customer requirements, there are no commercial build prices displayed on this site. Please contact us for a quotation.

What makes your greenhouses different to something else I can buy?

Our greenhouses have a life expectancy of 15 - 20plus years minimum. They require almost no maintenance You don’t need to shade them, the light is diffused so no scorching. The cladding ensures no shadows are cast so plants don’t struggle for light. The heat retention is superb – It’s like a duvet for your plants Our steel tube is galvanised inner and outer – Steel tube rusts from the inside out, but not if galvanised on the inside. Our steel is exceptionally strong with a high tensile rating. They are designed and manufactured to withstand the strongest wind speeds experienced in the whole of the United Kingdom, including the islands. Hebridian, Orkney and Shetland. They are safe, there is nothing to shatter. If accidently damaged they can be repaired just by the damaged section. They can be extended / adapted as the growing needs alter.

Can you make your greenhouses extra high for tree growing

In most cases yes

How is the greenhouse secured?

Commercial greenhouses have foundations as standard, these are 50cm cubed blocks at every 2m point around the base of the greenhouse. Also internally if partitions and walkway’s are required. In extreme environments and certain cases additional bracing and securing methods may need to be applied also. This would be discussed on an individual project basis.

Who does the foundation work?

We do.

Can I move the greenhouse?

Yes but please be aware larger greenhouses can be moved but as they have foundations would require specialist Keder knowledge to do so.

What is the lead time, for installation?

Commercial Projects typically within 2 months.

Can we provided scale drawings for planning purposes.


How much room do you need around the greenhouse to be able to build it?

Commercial greenhouse builds must have a minimum of 1m clear access all around the structure for movement of mechanical equipment I.e. mini digger, with good access for vehicles.

What ventilation options are there?

As standard our commercial greenhouses have manual drop down side vents, 1 each long side, which can be upgraded to electric thermostatically controlled if required. This system of opening from the top down ensures the best ventilation that removes excess heat faster than bottom up ventilation as heat rises. This system also means that the soil at ground level is no dried out, too quickly. Should you be looking at a multi-bay option we can look to lift the mid bay higher than the outer bay to allow eves heights vents also, we call this our cathedral system.
