Here you will find some inspirational pictures of how it is possible to turn a tennis court into a paddle court. Of course we are here for you and give you customized information (below is to be considered more general).
Normally a tennis court (unless it is a gravel court) is made on a soft base / surface, which means that a "reinforced wall / foundation" may be required for the construction. This is necessary when the construction is exposed to pressure / load through weather and wind, but of course also among the players who run into / lean / take speed / resist glass and posts. We recommend a 150 mm concrete slab over the entire course or a wall / foundation of 400x400 mm (see the concept description for PadelGrund which can be downloaded below). The outer dimensions must be at least 20.80x10.8 m as 20x10 m are the inner dimensions.
