This 8ft x 21ft Swan greenhouse, from UK manufacturers Swallow, is a terrific looking building that can stand on a standard board base or have a dwarf wall.
The frame is built from ThermoWood® so no preservatives are needed as all the Scandinavian timber has had the majority of its moisture removed by heat treatment. This prevents rot, warp and insect attack and so is superior in many ways to traditional timber. In addition to a natural or oiled finish, there are several colour alternatives for the frame.
Entering the greenhouse through double doors you'll discover a bright spacious interior with sunshine streaming through the toughened glazing that is sealed with silicone. To cool the greenhouse and regulate humidity, there are six roof vents fitted with automatic openers that will prove their worth if you are ever away from home.
Two front return stagings are already in place and more shelving and staging can be added to maximize the potential of this superb greenhouse. Guttering is also fitted as standard so that rainwater can be recycled and, to complete what is a tremendously well designed building, you can choose to have the porch extended to create an even larger growing area.
