The ‘Wall-holla’ is a multifunctional, modular play structure that we originally designed as part of a schoolyard. It was integrated in a sports court, solving a space and budget problem by combining sports, play equipment and safety surfacing into one object. Because of this, more than 60 children can play simultaneously, even though it is a very compact space. The vertical structure unites several functions which appeal to various age groups including lounging spaces, sliding, a crawl-through maze and climbing wall.
