1930s Bungalow Gets a Concrete Tree House like Addition

Located in Miami Beach, Florida the Sun Path House received a 3-storey concrete addition by Christian Wassmann. The spiral is designed to take advantage of the sun path as it changes its projectory over the course of the year. Separate from the main house, the concrete addition contains a ground level dining area, a second storey master bedroom and a roof deck on the 3rd storey.

The original home is a 1930s bungalow but the extension is definitely 21st century in design.

A concrete terrace connects the new structure to the house.

Although the top two levels are designed for privacy, the ground level is a place to entertain.

The master suite is cantilevered over the garden, and both it and the roof deck are covered in growing vines to enhance their privacy.

The master bedroom headboard wall is curved, wrapping around a round bed while hiding the open bathroom behind it.

A sauna on the roof deck is positioned to take advantage of the views while absorbing heat from the concrete wall, which just so happens to also shelter the sauna from winds.

The curved wall at the roof terrace maps out the path of the sun on a summer solstice.

Concrete home additions can be stand alone sculptural features like this one, compliment pre-existing structures or they can add a more modern aesthetic as in the case of this asymmetrical concrete architecture.
