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.

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 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.

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!
The roof and windows of the greenhouse are built with polycarbonate sheeting, a durable and strong plastic, with Twin glazing for added durability. Polycarbonate glazing is stronger than traditional glass, so you will not need to worry about it easily shattering and requiring replacement. The polycarbonate sheets allow natural lighting to the inside and allow enough heat for the plants to grow, so you can achieve the best growing results from your own garden!

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. Using the digital assembly instructions included in your order confirmation and with a team of at least 2 people, the handy pre assembled panels mean you will have your BillyOh building up in no time!

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.

Your order can be tracked through the account section on our website or by contacting us directly. You will be contacted after your order via your online account, email or text to provide updates on delivery dates.

BillyOh 4000 Lincoln Polycarbonate Greenhouse

At Garden Buildings Direct, our range of wooden greenhouses come with a number of features for you to choose from including clear and polycarbonate panel glazing and a selection of base sizes. This Lincoln quality timber greenhouse offers an affordable solution to growing in your outdoor space - perfect for the gardening enthusiast who needs some extra space!

Wood and Weather Protection Options

The strong timber frame of your Lincoln will come with golden brown spray treatment to protect it throughout delivery. However, optional pressure-treatment is available to offer an added level of protection in even harsh weather conditions. Our pressure-treated wooden greenhouses also come with an increased 15-year guarantee protecting your building against rot, insect infestation, and decay. Galvanised steel ironmongery is all used in all the fittings for protection in extreme weather. Otherwise, we suggest that you treat your wood after installation and again annually.

The Lincoln 4000 is a strong and traditional greenhouse made with a robust framework. The sturdy 11mm tongue and groove cladding is utilised in the sturdy panels of this wooden design.

Polycarbonate Glazing

Polycarbonate glazing has better heat retention properties than a glass greenhouse, allowing you to keep your plants in optimal growing conditions for longer. Twin wall polycarbonate panels are featured throughout the walls and the windowed roof of the Lincoln greenhouse to maximise on natural lighting throughout the day.

This garden greenhouse is surrounded by polycarbonate glazed windows offering great indirect natural light to all of your precious plants throughout the day. The Apex roof gives you a tall design with great head height and easy access to all areas of your greenhouse, complemented by the wide opening double doors. The building also comes with small but integral gutters that run down the roof edge to help move the rainwater away from the building and the entrance.

Base Size and Room For Potting Plants

The various sizes of the greenhouse suit a range of needs, from a thin greenhouse for smaller projects or hobbyists to a 12x6 greenhouse with increased floor space to easily fit all of your plants, projects, gardening tools, and even a potting bench! Shelving is a great addition to a greenhouse giving you extra storage by increasing your vertical space. This allows you to grow on the ground level while keeping all other gardening equipment safely stored away.

As with all of our greenhouses, this building is quick and easy to install and comes as pre-assembled panels. Simply fit the glazing into these panels, and you can begin to construct your building. Once completed, you have the option of keeping the classic style of your greenhouse, or as many of our customers have done, you can paint the greenhouse to suit your style.

Installation, Assembly and Assembly Kits

With a ridge height of 1.97m (6ft4) and eaves height of 1.52m (5ft), this wooden greenhouse shouldn't require planning permission so long as it isn't larger than 50% of your garden or built past the front wall of your house. Planning permission may vary, however, and we suggest you check with your local council if you have any concerns.

We don't offer an installation service on this garden building simply because its modular design allows for easy construction and the materials used ensure the dependable quality of all BillyOh greenhouses. Just follow the assembly instructions provided with your order and build your polycarbonate apex greenhouse onto a solid foundation like timber bearers and sub-floor or a concrete base. We also offer assembly kits with basic tools like a claw hammer to aid construction.
