If you only have a restricted space and need a productive, traditionally styled, greenhouse, then the Finch 12ft x 4ft Wide Lean To from Swallow will be the solution.

ThermoWood®, unique to Swallow greenhouses, is used throughout. Tremendously durable, it is heat treated Scandinavian timber with the moisture and resin extracted. The wood will not expand or contract, so warping is nothing to worry about. Neither is rot, even though no preservatives need to be used.

Inside you'll find wonderful growing conditions. Temperature and humidity are controlled by two automatic roof vents, and there's staging already in place along the length of the greenhouse, so you can immediately start propagating a large variety of plants.

Light streams in through 3mm toughened glazing, this is fitted into grooves and then sealed with silicone. For security the single door has a mortice lock.

If you want to re-cycle rainwater, there is an option for a water collection system and a high level shelf will always prove useful. As delivery and installation are included in the price of a greenhouse this all adds up to a very attractive greenhouse whatever way you look at it.
