TGB Sunningdale Combination Summerhouse
Sunningdale Combination Summerhouse
The TGB Sunningdale Combination is the ultimate dual-purpose garden building — combining a stylish modern pent-roof summerhouse with a practical storage shed in one beautifully designed unit. Perfect for those who want a relaxing retreat and a secure place to store garden essentials, this versatile model makes the most of every inch of space.
The bright, fully glazed summerhouse section provides a comfortable, light-filled area for relaxing, working, or entertaining, while the adjoining storage room keeps your tools, furniture, and outdoor equipment safely tucked away behind a solid timber partition.
For complete flexibility, the storage section can be positioned on either end of the building, and you can choose your preferred internal split between the summerhouse and storage area — allowing you to tailor the layout perfectly to your garden.

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.
