Our View
The Swallow 4x4 Lark is an exceptional greenhouse, made to make the most of your space with a comfortable working height this Thermowood greenhouse comes fully installed!
All Swallow greenhouses are now made from Thermowood.
Heat and steam are used to thermally modify the wood to produce an exceptionally strong and durable wood that is perfect for outdoor use.
This process is achieved using natural methods and is non-toxic and chemical free, with one of the many benefits being improved insulation well suited for greenhouses.
After treatment the wood is a beautiful consistent colour that will last far longer than normal treated timber. Swallow greenhouses are delivered and installed at the same time by Swallow. A firm and level base area will need to be ready such as slabs, concrete, decking, sleepers or similar.
