The 200 square meter split-level houseboat on De Omval keeps a low profile to respect local building ordinances. Part of the home is submerged underwater, but +31 Architects made sure to provide daylighting down below by creating a large void from the top floor down to the bottom floor. A `cuckoo window' under the fireplace on the top level lets light into the bedroom below.

A staircase on one side of the house leads up to the rooftop deck, then down half a floor to one of the bedrooms. The staircase continues down another half floor to the bottom level, which features a study, a master bedroom and bathroom and space for technical equipment. The top floor holds the the kitchen, dining and living areas and features large floor-to-ceiling windows on the canal side.

The water villa was recently completed and launched at De Omval, and it offers sweeping views of the nearby Amstel River. A wood planked jetty leads up to the site, and a deck on the opposite side of the house allows the owners to moor a boat alongside it. While the river and canal levels are kept pretty constant in the city, the home could easily adapt to rising sea levels and a changing climate.
