Delicately nestled in the bustling heart of Osaka, Japan, Rooftecture OT2, designed by Shuhei Endo in 2012, is an expression of architectural ingenuity and thoughtful design.

Within the constraints of a small, urban site, Endo crafts a serene oasis for a family of five, deftly balancing the desire for light and air with the need for privacy from the surrounding cityscape. This enchanting abode embodies a sophisticated duality; its exterior exudes a bold metallic presence, while the interior emanates an ethereal warmth and connectivity.

Endo's ingenious use of perforated metal steel sheets on the façade stands as a testament to his ability to harmonize functionality and aesthetics. The unique wall formation disrupts visual penetration from the bustling street, while simultaneously allowing for an abundance of light and air to permeate the living spaces. An openable skylight in the central stairway creates a harmonious microcosm of the outdoors, allowing gentle breezes to waft through the home. As day turns to night, the folded plate design casts a mesmerizing dance of light and shadows on the exterior, a subtle symphony reflecting the changing moods of the interior.

The pièce de résistance of Rooftecture OT2 is undoubtedly the luminous atrium space that lies at its heart. With its "skipped floor" design, the atrium unites family members on different levels through visual connection, fostering an enduring sense of togetherness. Contrasting the bold metallic exterior, the interior walls and ceiling are adorned with "Harvest Panels", bestowing the space with a soft, almost ethereal quality.
