Yes! This greenhouse includes a strong, galvanised steel base. This allows it to be light and easily transported while giving your greenhouse protection from bugs and excess moisture. It is easily cleaned and gives the structure the strong, perfect foundation it needs to resist rust and keep your building sturdy for years to come.

Yes, a great feature of the Lean-To 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 you grow healthy vegetables and flowers.

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

Integrated Guttering - To effectively move water away from the entrance of the building.

Sliding Door - This will help to prevent the door from slamming in harsh weather.

Roof Vent - This helps to regulate temperature and air flow to your plants.

Rust Free Framing - Aluminium framing gives peace of mind when it comes to rust.

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

This means that the structure is designed to rest against the side of another structure to save space and give it support. This takes advantage of an existing structure to save you time and money over a standalone building. Plus, it potentially offers several benefits including insulation for your home and a more stable temperature for growing.

We do not offer an installation service on any of our buildings, our buildings are designed & made to be easy and simple to assemble. Using the assembly instruction included and with a team of just 2 people and a bit of DIY knowledge you can expect to have your BillyOh building up within a day, or as little as 3-4 hours with some of our smaller buildings.

You can place this building against any strong wall or fence. It is designed to easily be supported by any wall of your home or if tall and sturdy enough your property fencing. You should face the structure toward the south to give it the most sunlight all year round. This will extend the growing season and give you the best results.

No, our lean-to greenhouse has one front-facing wall and two side walls. The rear wall comes from your home or another structure. This has many benefits. First, it saves you money over a standalone structure, and second, the walls of our homes generally store extra heat during the day and release it throughout the night. By placing the structure adjacent to this, it can achieve a far more stable temperature than a stand-alone model and even help insulate your home.

Your order can be tracked through the account section on our website or by contacting us directly. You will be contacted after your order by our helpful care team to arrange delivery of your building.

We offer a pay by finance option on any purchase over the value of £560.
