Willem81Hello everyone,
we have now been living in our own home for about 1.5 years and are very satisfied with everything. We have a beautiful wooden house with solid CLT wooden walls and feel lucky every day because of the great indoor climate, the attractive appearance, and the fact that we actually stayed within budget.
There is really only one thing we don’t like: our terrace. The house is surrounded on all sides except one by a path made of anthracite-colored paving stones, which lead into terrace areas on two sides (one area measuring 4 x 4 meters (13 x 13 feet) and another 6.5 x 2.5 meters (21 x 8 feet)). The wide terrace runs directly along the southern gable end of the house. The roof and exterior walls extend out a bit further. In this area, Douglas fir decking boards were installed (about 1.20 m (4 ft)). Then there is a step down and the stone terrace begins.
Long story short: we don’t like the paving stones and would prefer to cover all the areas with Douglas fir decking, which would also match the house much better. Of course, this is something we should have thought about earlier. It has only just dawned on us (independently of each other) that it’s the terraces that somehow don’t quite fit.
The question now is: do we need to remove the stones, or could the terrace substructure also be placed directly on top of the paving stones? Relevant guides recommend first excavating the soil, then laying gravel or sand with a slight slope, weed control fabric, and concrete paving stones spaced according to the substructure, so that the substructure can be fixed onto them and then the decking boards attached. But couldn’t the substructure be screwed directly onto the paving stones? To ensure ventilation of the substructure, adjustable feet or something similar could be used. What do you think? I would appreciate your advice. Thank you!

You will build a substructure, either using WPC boards or wood. The substructure must not rest directly on the paving because of moisture.
You can either place decking pads underneath or use deck supports, which are a type of stilts available in various sizes.
Before starting, you should measure how high the deck can be so that, for example, the patio door can still open.
Take a few photos and measure how many centimeters (inches) of clearance you have.
