Building a terrace starts with carefully constructed foundations. A durable, safe, and properly built terrace will bring joy for a long time. Check out our checklist for proper terrace construction.
The first, and arguably the most important thing is the foundation of the terrace. The style and method of the foundation are determined by the soil. A simple pillar foundation is the easiest and most effortless solution if the ground is frost-free. If the ground is frost-prone, seek advice from a professional for foundation construction.
At this stage, it is also good to ensure sufficient height so that the terrace ventilates effectively and no vegetation forms there. If the terrace is placed on the lawn, the topsoil must be removed, a filter fabric laid underneath, and a layer of gravel placed on top.
Stone slabs are well suited for frost-free soil foundations.
Frame
We recommend using only stainless or acid-resistant steel screws and fasteners in the frame. Choose sufficiently sturdy material for the frame such as 48×98 Frame Plank. Carefully check the diagonal measurement and frame height either with a laser meter or level. Also consider walking directions and possible stairs at this stage.
Joist spacing usually varies between 400-700mm. The joist spacing is determined by the decking material and its dimensions. 600mm spacing is a common choice for 28mm thick boards.
Decking
There are many good material options for terrace decking. Once a preferred product that best serves your use is chosen, installation can begin. It is recommended to start installing the deck boards from the front edge. The result is neater and the work easier if the board is the full length of the terrace. We recommend leaving a 5mm gap between boards. If the board is wet, use a smaller gap, as wood shrinks when drying.
Wood composite installation is done with hidden fasteners.
Other considerations
- Schedule and budget
- Check building permit matters with the building supervision authority
- Board direction: do you want to emphasize width or length?
- Board width: Wider boards for a massive look and narrower for a more subdued appearance
- Supplies: Deck boards, frame planks, screws, foundation materials
- Tools: Cordless drill, saw/circular saw
Maintenance-free and shape-retaining wood composite terrace board is an easy choice when you want durability and ease from your terrace.
