Write the first review


The Kingfisher 6ft wide x 18ft Greenhouse is traditional in design but has been constructed using revolutionary ThermoWood®. This is heat treated timber which has had its naturally occurring resin and moisture extracted.

A very durable and long lasting building material is the result, which will suffer minimal shrinkage and expansion. No preservative is required as decay is unlikely and warping should also not be a problem.

Four vents, that are fitted with automatic openers, will introduce fresh air together with regulating temperature and humidity. So the interior is a very productive environment. Other standard features include toughened glass with a silicone seal and full length staging.

If you want to add options, there is a kit so that rainwater can be recycled, and various types of shelving and staging. In addition, why not add a combination shed to create even more working and storage space. 

Delivery and installation of this very attractive structure, built by British craftsmen, is included in the price.
