Cosmos Initia Launches Website for 'Initia Forum Futako Tamagawa The Hill,' a New Detached Housing Project in Seta, Setagaya

Cosmos Initia (Headquarters: Minato-ku, Tokyo; President: Ryotaro Takachi), a member of the Daiwa House Group, launched the official website for its new detached housing project, 'Initia Forum Futako Tamagawa The Hill' (located in Setagaya-ku, Tokyo, 5 units), on June 4, 2026.

Location: Enjoying both the Vibrancy of Futako Tamagawa and the Tranquility of Seta

The view from Gyozen-ji Temple in Seta, Setagaya-ku, has been cherished since the mid-Edo period as one of the 'Eight Views of Tamagawa.' Located on the 'Kokubunji Cliff Line,' a series of cliffs covered in lush greenery, this area has a storied history since the Meiji era as a preferred location for villas and residences of political, business, and cultural figures, symbolizing the prestige of living on high ground.

Architectural Concept by Yoshiro Goya of atelier9

'Initia Forum Futako Tamagawa The Hill' was designed by Yoshiro Goya of atelier9 Architectural Research Institute, inspired by the historical depth of Seta 4-chome. Each residence features a private approach connected directly to the public road. The layout maximizes the east-west orientation, with large southern openings in the interior, allowing for abundant light and expansive views of the sky from the second-floor living rooms, free from external intrusion.

Achieving Both Openness and Privacy

The design creates a sense of space exceeding the physical dimensions by carefully interpreting the relationship between neighboring houses and sharing outdoor space. By offsetting the vertical volume of the buildings, the ingress of light and sightlines are precisely controlled, creating a delicate balance of quiet openness.
