Extra Timber Base — Timber Base Tunnel Houses & Shade Houses

⚠️ Please note: This add-on is only compatible with timber base tunnel houses and shade houses. It is not suitable for aluminium framed structures. If you have an aluminium framed tunnel house or shade house, please do not add this to your cart.

Add extra height to your timber base structure with an additional tanalised timber base rail. Adds +100mm of height to your existing base, giving a total base height of 200mm x 50mm (8x2).

A higher base provides more headroom inside the structure and creates extra garden bed depth on your existing ground — ideal for raised bed growing or sloped sites.

Please note: Additional base timber does incur an extra freight charge.

Select the size that matches your tunnel house or shade house below.
