Steel Fins Create A Sculptural Facade For This Home

Realrich Architecture Workshop has shared photos of a modern home they completed in Jakarta, Indonesia, that features operable steel fins on the western and southern facades.

To fins were included in the design of the house to regulate light and airflow. These fins extend into a 3.5-meter canopy on the ground floor, providing shade that mimics the coolness of sitting under a tree.

This canopy not only protects surrounding plants from harsh sunlight but also blurs the line between indoor and outdoor spaces

The facade’s curved forms enhance the organic feel of the home, making the house appear as though it grows naturally from its surroundings.

The construction of Lumintu House showcases the skill of local craftsmen who collaborated with the studio. Each steel component was meticulously bent by hand, while concrete catenary openings were shaped to support large glass elements and evoke the metaphor of Plato’s cave—a space of light and shadow.

The shaded entryway of the home also includes a circular opening that provides a glimpse of the pool on the other side of the wall.

The pool, which is shaded by the screens, runs along the living room and aids in keeping the home cool.

Inside the home, the ground floor features a foyer with a piano and sitting area, living room, dining room, kitchen, guest room, and an expansive 11-meter column-free main area that flows seamlessly into an outdoor space and inner courtyard, enhancing the sense of openness while promoting natural ventilation.

On the upper floor, three bedrooms, a gym, and a home office provide ample living and working space, while the service area, discreetly positioned at the back and integrated into the mezzanine level with the gym, offers separate access for convenience.

On the roof, a garden and light canopy provide insulation and a private dining area, adding functionality and charm.
