The Westminster keeps its depth to 330mm for narrow positions beside a wall or tall fence. Its interior is designed around a standard seed tray. This makes it a practical option for a side passage where a deeper greenhouse would take more space.

Eight shelves provide separate levels for seed trays. Adjust their heights as plants develop, or remove shelves when you need more vertical room. They can also drop flat. Slim aluminium shelf bars reduce shade over plants below, while the 4mm toughened glass admits light.

The doors slide within the greenhouse footprint, so there is no outward door swing across the passage. Open them gradually to adjust ventilation. Sliding roof panels give another opening above the plants. Plain aluminium is standard, with optional colour coating. Compare depths across our Access mini greenhouses before choosing your position.

Practical setup note

We recommend measuring the remaining passage space as well as the greenhouse depth. Full colour assembly instructions are included. Shading and shelf covers are available separately.

Can I fit an automatic louvre vent?

No, louvre vents cannot be fitted to this model. Ventilation is through the sliding doors and roof panels.

Is mist watering included?

No, mist watering is excluded from the Westminster. Plan how you will reach the trays for watering.

Can the shelves be moved?

Yes, all eight seed tray shelves are height adjustable. They can also be removed or dropped flat as your growing layout changes.

Frequently Asked Questions

  • Can I choose which side the louvre and watering system go?

    Yes, you have flexibility in positioning these features. The watering system connection can be fitted on either end for Classic models, while the louvre vent typically fits on the left but can be adapted for the right side.

  • Does the mist spray affect the wall?

    The mist spray uses less water than natural rainfall would on the wall, so it shouldn't cause any issues. The greenhouse actually provides some protection to the wall from the elements.

  • Can I automate the watering?

    Absolutely! We offer a hose end timer that can automate your watering system, perfect for when you're away or busy.

  • How does the louvre vent work?

    The louvre vent is a clever, sun-powered device that doesn't require electricity. It uses an oil-filled cylinder that expands with heat to open the vent and contracts to close it as temperatures drop.

  • Is the greenhouse easy to build?

    Yes, our greenhouses are designed for easy assembly. We provide clear, comprehensive instruction booklets with step-by-step guides to make the process straightforward.

  • Do I need to fix the greenhouse to a wall?

    While walls are ideal for their heat-absorbing properties, it's not necessary. We offer glass-backed models for freestanding options if you don't have a suitable wall available.
