Write the first review


A Kingfisher 6ft wide x 20ft Greenhouse, similar to others in the range, is constructed with ThermoWood®. This is a revolutionary heat treated timber that is unique to Swallow.

With very little moisture remaining, the timber is highly durable and will have minimal expansion and shrinkage. Warp and rot will not therefore be a problem and no preservative is required.

Inside this attractive traditionally styled greenhouse, the four automatic vents create a good flow of air, controlling temperature and humidity. Consequently the environment will be very productive and a pleasure to spend time in.

There are many other standard features, including the toughened glass that's silicone sealed, and full length staging. As an option you might choose a rainwater collection kit and there's different styles of staging and shelving. You could also add a combination shed to create even more space. 

Built by British craftsmen, delivery and installation is included in the price.
