About Our Bespoke Greenhouses 🌿

Welcome to our collection of Bespoke Greenhouses, designed for serious gardeners who require a robust, architectural growing space tailored to their specific needs. Our range features the premium Belgian bespoke glasshouses manufactured by Janssens, renowned for their immense strength and "Box Section" aluminium profiles. These heavy-duty structures are available in widths ranging from 7ft up to 19ft, offering ample space for any horticultural project.

Unlike standard models, our bespoke range offers superior durability with a 13-year warranty, 4mm toughened safety glass, and high eaves (2m) for maximum growing height. Whether you need a specific colour to match your property—available in Silver, Green, White, or Black—or a unique configuration with partition walls and extra-wide sliding doors, we can deliver. For those with limited space, we also offer space-saving attached designs in our Lean-to Greenhouses collection.

Frequently Asked Questions about Bespoke Greenhouses

• Do I need planning permission for a greenhouse in my garden?

  In most cases, no. Greenhouses are usually considered "Permitted Development" provided they meet height and location restrictions, such as not being in front of your house or exceeding 50% of your garden area. Always check with your local council if you live in a Conservation Area.

• How close to a boundary can I build a greenhouse UK?

  You can build close to a boundary, but if the structure is within 2 metres of the boundary line, the maximum height of the greenhouse (including the roof ridge) must not exceed 2.5 metres to comply with Permitted Development rights.

• Does a greenhouse need a concrete base?

  Yes, heavy-duty bespoke greenhouses require a solid, level foundation. A perimeter concrete strip or a solid concrete pad is recommended to support the weight of the glass and frame. Alternatively, some models can be installed on a dedicated box section base plinth on top of slabs.

• Is it cheaper to build your own greenhouse or buy a kit?

  Buying a kit is generally more cost-effective and safer than building from scratch. Our bespoke kits, starting from £1425, include engineered structural integrity, toughened safety glass, and warranties that self-builds cannot match, ensuring your investment lasts for decades.

• What is the best direction for a greenhouse to face?

  For summer crops like tomatoes, a North-South ridge orientation is best to prevent overheating. For winter crops and early spring starts, an East-West orientation captures the most sunlight. Position the door away from prevailing winds where possible.
