Come with us on a tour of Dutch architect Julius Taminiau's Amsterdam houseboat, which he shares with his girlfriend and their 2 children. Inspired by the consistent sizing of Japanese tatami mats, the 1,700-square-foot floating home  is balanced and harmonious.

The mostly custom interior furnishings are made of birch plywood.

Because of the grid design, "everything is and feels related," says the architect.

The few furnishings that were not custom designs are a mix of vintage items and Ikea.

A staircase between the living and dining room leads to the roof deck.

Instead of a television, the view from the living room sofa looks out onto the floating community.

Oak wood stairs lead from the front door to the main (second) level.

The exterior is clad in engineered wood panels that are specifically made for marine environments.
