This wooden greenhouse is constructed from 12mm tongue and groove with a smooth-planed finish, making it strong, durable and incredibly stylish. All of the wood is PEFC-certified, so only sourced from sustainable, well-managed forests. Pressure treated to prevent rot, no retreatment is required, saving time and money.

The glazing is made from styrene, which is completely shatterproof and recognised as being far safer than conventional glass.

Easy access to the greenhouse is gained via a single door, which can be fitted with either a left or right-hand opening. Two removable shelves allow a wide range of plants to be grown, while the automatic vent ensures they always enjoy optimum growing conditions.

Fixings and instructions are both included for an easy assembly.

Why choose a Forest Georgian Greenhouse?


Why choose a Forest Georgian Tall Wall Greenhouse?


This gorgeous greenhouse’s clever design gives you room to grow your own produce without dominating your garden. This means you’ll still have plenty of room for everything else you love doing too. Enjoy the best of both worlds with Forest’s Georgian Greenhouse.


Pressure treatment forces preservative deep inside the timber. This provides unbeatable protection against rot and fungal decay.


The 2 removable shelves offer you the chance to grow a huge range of plants.


The automatic roof vent regulates the temperature inside to ensure your plants enjoy optimum growing conditions - even when you're not around.


The greenhouse glazing is made from styrene, so enjoys excellent light transmission, is far stronger than conventional glass and completely shatterproof.


You can gain easy access to your plants through the glazed door, fitted with a latch, and which can be assembled with either a left or right-hand opening.


Why not paint your greenhouse to add your own personalised touch, just like Forest have done here?





A smart solution for smaller gardens or tight spaces.



Expertly crafted from superior 12mm tongue and groove, this lean-to greenhouse is fitted with a solid back panel, making it versatile enough to use anywhere in your garden.








The Pressure Treatment process for timber has been applied to products for a number of years; the key benefit of this process is that the preservative is forced under vacuum pressure right deep into the heart of the wood and the grain structure. The preservative becomes an integral part of the wood; giving a long life and protection against rot.


This process also means that you never have to apply preservatives to your greenhouse, and it allows the natural colours of the timber to show through and so your greenhouse blends easily within your garden. 



Timber is loaded into chamber and a vacuum empties timber cells of air.



Cylinder is flooded under vacuum with preservative.


Preservative is forced deep into timber using hydraulic pressure.



Another vacuum extracts excess preservative.



Timber draws in surface excess of preservative under low pressure, then is left to dry.
