Houseboats have been around for quite a while, and the Dutch have built some extraordinary ones. Building floating neighborhoods is the next obvious step, as development pressure is making terrestrial resources increasingly scarce. The 75 mixed income units on the Steigereiland (Jetty Island), located on the IJ Lake, are very similar in look, with only subdued colors and various heights distinguishing them from each other. The triangular dock layout and differing distances between rows help keep the development from becoming too uniform. A ring of similar-looking homes on the adjacent dike maintain the clean aesthetic.
