Walking along the promenade you'll see an extraordinary very Gaudi-like building nicknamed Crazy House compared to its Bauhaus neighbors. Its architect Leon Gaignebet fought for the building permission for seven years and his major idea was to separate the sea from the city, that's why the exterior is paneled with industrial concrete and metal but interiors are beautiful shell-embellished mosaics with plants and sand. Walk around and try to get inside to admire this work of art. If you walk southwards, you'll spot another unusual building. It's quite new but looks original amid typical Tel Aviv houses.
