Frequently Asked Questions


No, this greenhouse does not have a base or floor. To further improve the structure of the greenhouse, a base is available, providing a sturdy foundation. All garden buildings should be assembled on a firm and level base. A base will ensure your building has a solid, long-lasting and well-drained foundation.
To aid with organisation of your plants and tools inside of the greenhouse, shelving is an optional extra, available on one side, both sides or to go all around your greenhouse. When growing plants, water is vital, and with the Lincoln you can add guttering. The Guttering will collect any rainwater for you to use when watering your plants, a great cost-efficient option!

Spray Treated: Our greenhouses get a beautiful golden brown spray treatment before leaving the factory in order to preserve the quality of the wood up in until the delivery. As this only lasts through the transit stage, we do advise treating the wood after installation to protect and preserve it, as well as annual maintenance.

Pressure Treated: For an extra level of protection, you can opt for a pressure treated building which is an effective way of keeping the wood long lasting. This is an extra step in the manufacturing process where the wood is treated in a pressurised tank. Chemical preservatives are forced deep into the wood’s fibres to resist rot, decay and termites. When you upgrade to Pressure Treatment, the guarantee is extended from 10 to 15 years.

Yes, a great feature of the Lincoln Greenhouse is the Adjustable Roof Vent installed on the roof. The opening roof vent allows you to better control the ventilation and air circulation inside your greenhouse, helping you to effectively grow your plants. The vent also allows you to regulate the temperature, so you can prevent overheating and help your plants to cultivate healthily.
The walls of the greenhouse are built with styrene sheeting, a clear durable and strong plastic. a safer alternative to traditional glass that is essential if you have a busy garden or young family. The benefit of styrene is not only does it allow natural light to flood the interior, promoting photosynthesis, it also protects your produce from harmful UV rays. The roof is made using a hard-wearing polycarbonate that allows plenty of natural light in, ensuring your greenhouse is light, bright and well ventilated.

If your building is shorter than 2.5m you should not require planning permission, (unless it’s more than 50% of your garden or will be placed in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before purchasing a garden building from us.

We do not offer an installation service on any of our buildings, as they are designed to be easy and simple to assemble.

Our sheds, greenhouses and summerhouse are delivered in easy to assemble panels. For your convenience the panels are no wider than 4ft so they can be easily maneuverable and fit through a standard doorway. Glazing and any additional wood is delivered in separate, clearly labeled packages.
