Hong Kong studio Davidclovers have covered the interior of this house in aluminium strips to create patterns of light and shadow that change throughout the day.

Situated at Clearwater Bay in Hong Kong and called House DE, the design merged two existing homes into one,  joined by three staircases.

The undulating fins admit natural light through the ceiling during the daytime while emitting artificial illumination at night.

Here's more from the architects:

House DE is an “infill” townhouse, spectacularly sited on a hillside above Clearwater Bay, Hong Kong.

Combining two existing units into one, the design uses the volumes of three staircases to blend, burrow and interlock spaces vertically across four floors.

Each “interaction” is materially monolithic, using stone, wood and a series of delicate aluminum fins.

Defined by these fins, the texture and form of the lantern-volume subtly changes shape and depth, casting shadow and emitting light in different ways throughout the day.

Each stair-volume pries open the house vertically and horizontally, pulling in daylight and emitting artificial light.

Thickening the existing building enclosure and stretching it across the front and rear, the bedrooms and new master suite on the upper floors are protected from the elements, yet opens up to views of the natural surroundings.

Towards the South, the facade thickens and torques, providing shade for bedrooms and balconies; while on the North, the facade transforms into a garden trellis for an outdoor dining terrace.
