Where space is limited this Thermowood Lean-to Greenhouse with Toughened Safety Glass is the ideal solution for the keen gardener. The contemporary design uses sustainable, natural materials which will blend perfectly into any garden space. This Lean-to Greenhouse offers superb quality at an amazingly low price which includes lockable door, damp seal, staging down one side, automatic roof vents and installation. Each greenhouse comes with a turned apex finial to add to that timeless, classic look.  Made in the UK by skilled craftsmen from thermally modified Redwood Pine which is used extensively in Scandanavian countries because it is a much more stable product than ordinary kiln dried pine. The process involves baking the wood at a high temperature in a sealed oven from which the air is pumped out. The result is a timber which has improved qualities and high durability with almost no warping, shrinking or swelling. Another advantage is an excellent finish which needs no preservative treatment saving time and money year after year.  If you prefer a painted finish the super smooth surface makes painting so much easier (similar to painting metal). This process also changes the colour of the pine to make it similar to that of Cedarwood. This colour can be maintained by occasionally applying a coat of standard timber treatment but this is optional. Left untreated the wood will age to a lovely grey colour, as seen in modern sustainable architecture. If you prefer a factory painted version we offer this model in a range of heritage colours, please contact is for details if this is of interest. This greenhouse was voted 'Best in Class' at the GLEE Trade Show

Delivery & Installation: All buildings are built to order and supplied in approximately four weeks from the base being ready but the lead time can extend to five weeks during busy periods such as March to May. The customer needs to prepare a firm level base using the base plan provided and before the fitters arrive. This is normally contructed from concrete or paving flags.  For a lean-to greenhouse it is very important that the base is level and at a 90 degree angle to the house wall. The wall on which the lean-to is fitted must be flat and clear of any obstructions such as drainage pipes, cables, etc. If the wall is made of stone or uneven then some extra preparation may be needed - please call us to discuss before you order. The manufacturer will contact you shortly before delivery to make sure the base is ready and to arrange a suitable day for installation. The installation team take approximately 2 to 3 hours to build your greenhouse and all customers so far have been highly delighted with their purchase. Every building includes a 12 month guarantee
