Swallow Heron 6x8 ThermoWood Lean To Greenhouse with Installation

Write the first review


The Heron 6ft x 8ft wide Wide Lean To Greenhouse is a compact timber structure, the smallest in the range, that will be a useful and attractive enhancement to your home.

It's built by British craftsmen in traditional style but uses heat treated ThermoWood® which has many advantages over normal timber.

With moisture and resin excluded, the wood is extremely durable and won't shrink or expand. With no rot or warp to worry about, no preservatives need to be applied.   

Many features come as standard, the roof vent for example opens automatically, extremely useful to prevent overheating if there is no-one available to open it manually. Toughened glazing, which is obligatory if the lean to covers an entrance, is silicone sealed.

Full length staging is fitted along one side and can be extended to form a 'L' shape. Due to its generous width, double doors with a mortice lock can be located at either end.

A very neat lean to that will satisfy the needs of a hobby gardener and will be delightful addition to any property, built to last and with delivery and installation included in the price.
