Description

Hercules Octagonal – 6’3″ x 7’11”

A characterful centrepiece with exceptional strength and year‑round growing performance.

The Hercules Octagonal brings together classic garden charm and the renowned engineering of the Hercules range. Its elegant eight‑sided design creates a standout focal point while offering excellent light distribution, reduced shadowing, and a surprisingly spacious feel inside — whatever size you choose.

Built around an extremely strong aluminium frame and finished with a powder colour finish, this model is designed for stability, longevity, and everyday practicality. It comes glazed with toughened safety glass and finished with bar capping, giving a clean, secure, premium look that enhances the structure’s strength.

Specification

• Toughened glass
• PVC bar capping to hold in the glass (no clips)
• Good quality Hercules sliding doors with low threshold and lock
• Automatic roof vents – (N/A on 6’3″ x 6’3″ model)
• 2 x louvre windows in the sides
• Toughened glass kick panels around the bottom (so that only a small pane would break if a stone is flicked up from a lawnmower for example)
• Tanalised timber staging each side (high level shelves are optional)
• strong box section corner bars

You can also add the optional high level shelves to make even more useful space.

Please note that the bottom door track needs to be supported by the level base as it protrudes proud of the greenhouse footprint.

Installation & Base

Installation services are available via Bourne Buildings in some locations

We cannot emphasis how important it is to have a proper base for your Greenhouse to be erected upon. It is essential that the BASE IS COMPLETELY FLAT, LEVEL AND SUBSTANTIAL enough to take the weight of the greenhouse including its glass.

Give yourself enough room around your base to allow for fitting the glass and any on-going maintenance / cleaning. A slab base which is larger than the greenhouse is the ideal solution. Slabs are ideal because they allow for some drainage between them (no greenhouse is 100% waterproof) and they will also help support the lower door runner and threshold.

Clearance

We recommend at least 18” clearance all round for installation, airflow, and future maintenance.
