I am puzzled as to why the myth persists that a wooden terrace is cheaper and above all easier than one made of porcelain stoneware...
Frost protection, gravel, that’s also needed for the wooden terrace. With stone, you’re basically done then and can lay the tiles, compact, fill joints with sand. All set. With wood, it’s just beginning. Bitumen pads against rising moisture. Build and level the substructure. Then fix the wooden decking boards with hundreds of screws, including pre-drilling. Don’t forget ventilation grilles on the sides...
And the price? Sure, if you get the Douglas fir junk from the hardware store, then for 30m² it’s around 800-1,000 EUR. With good care, it lasts 5 to 10 years. If you want something decent, like oak, bangkirai, robinia, ipe... then 30m² quickly costs 3,000-5,000 EUR, just for the boards. Without substructure, without ventilation...
You can get porcelain stoneware at the hardware store, where you also get the Douglas fir, already for 30, 40 EUR/m².
A durable wooden terrace is much more expensive than its counterpart made of terrace tiles. With natural stone, the costs might equalize, but hardly anyone does that. You choose wood because you want it... not because it’s cheaper or easier. Anyone who can’t get a stone terrace perfectly even won’t manage it with wood either.
