TGB Octagonal 8 and 10 Summerhouse
An eight-sided garden retreat
The TGB Octagonal 8 and 10 Summerhouse creates a distinctive garden retreat with its eight-sided design, tiled roof and traditional joinery. Choose an 8 × 8ft or 10 × 10ft building to suit your outdoor space.
Two fully glazed top-hung opening windows and two fully glazed fixed windows bring in light and ventilation. Panels of the same size are interchangeable during installation, helping you arrange the building to suit your garden.
The 8ft model has a half-glazed single joinery door; the 10ft model has double doors. Antique hinges, an ornate handle, a lever lock and a door drip complete the traditional detailing. Choose Georgian, diamond lead or square lead glazing and a tiled roof in red, slate, green or black.

Warranty & looking after your building
Manufacturer guarantee cover depends on your chosen building and finish. Standard, Premier and Loglap cladding carry a 1-year manufacturer guarantee. Where offered, Tanalised pressure-treated cladding carries a 15-year manufacturer guarantee against rot and decay. Please check the options available for this model.
Protect your building after installation
Your unpainted TGB building is supplied with a pretreatment. Paint it as soon as possible after installation with a good-quality exterior timber paint suitable for garden buildings, following the paint manufacturer’s instructions for preparation, timber moisture and drying conditions. A suitable finish helps protect the timber from rain, moisture and weathering.
Tanalised timber still needs painting and maintenance
Tanalised pressure-treated timber also needs a suitable exterior paint finish and ongoing care. Its 15-year manufacturer guarantee against rot and decay does not replace painting or regular maintenance, and does not mean the building is maintenance-free or waterproof.
Factory-painted buildings
If you choose a factory-painted building, the initial paint finish is already applied. Inspect it after installation, touch up where needed and maintain or repaint it in line with the manufacturer’s guidance.
Ongoing care
Check the paint finish regularly and touch up or recoat as needed, following the paint manufacturer’s maintenance schedule. Keep gutters and drainage clear, inspect the roof covering, keep vegetation away from the walls and maintain a level, well-drained base. Contact us if you would like advice on choosing a suitable paint or caring for your finish.
Frequently asked questions
Will I need a base?
Yes. Your building needs a firm, flat and level base, correctly sized for the floor area. We can advise on your base and quote for timber-frame or concrete options.
Can I see a building before deciding?
Of course. Visit us at Highdown Garden Centre in Angmering or Squire’s Garden Centre in Washington. Please call first to check whether your preferred style is on display.
How will delivery be arranged?
We will contact you after your order to confirm access, base readiness and installation arrangements. Lead times are estimates and we will confirm your delivery date when your order is processed.
Who will look after my order?
You’ll speak with Ashley or Jacquie throughout, so you’ll have familiar people to contact who know your plans. Our own local two-person installation team takes care of the build. From your first enquiry to installation day, it’s a small, friendly team with practical advice and personal service.
