The design for the world’s first freeform 3D-printed house will be made a reality after Wimberly, Allison, Tong & Goo (WATG) won a contest aimed at architects, designers, engineers and artists.

Their Urban Architecture Studio has been awarded first place for its unique design, called the Curve Appeal, in Branch Technology’s Freeform Home Design Challenge.

WATG’s Chicago-based team – consisting of Daniel Caven, Chris Hurst, Miguel Alvarez and Brent Watanabe – came up with this proposal which captured the potential for 3D printing to revolutionise design and construction.

The house will be located in Chattanooga, Tennessee in the US, and the 3D printing for it is expected to begin next year.

Participants in the contest had to design a 600-800-sq ft (56-74-sq m) single-family home. It had to be “freeform” – meaning the buildings couldn’t be regular or formal shape – and it had to include a kitchen, a bathroom, a living area and a bedroom.

To create two walls, the roof and the interior core of the Curve Appeal model, 28 3D-panels will be printed off-site then slotted together. These four main sections will then be hoisted into place and joined together.

The home looks like it will have open, light-filled living spaces. There are also large pieces of glass to connect the occupants to the outside and to nature.

Other aspects of design that the WATG team had to consider for Curve Appeal include mechanical, electrical, plumbing and lighting requirements – and they also had to allow for solar design strategies.
