Architects David Ben Grünberg and Daniel Woolfson of D * Haus Company created a dynamic house inspired by mathematician Henry Dudeney. In winter the house is enclosed in a square formation, with small windows.
As the seasons change and the climate heats up, the house is "open" like a flower, to allow more light and air to enter the interior that offers plenty of panoramic views of the surroundings. Internal walls become exterior walls, windows and doors become windows become doors. This house has never been made in the history of architecture.
