Project Details: Casa 9, a Serene Retreat by Hoang GK
Designed by Hoang GK, with Pham Thai Cong Hoang as the lead architect, Casa 9 is a remarkable house located in Dong Nai City, Vietnam. Completed in 2025, this 219 square meter residence is envisioned as a private sanctuary for urban families seeking respite from city life. The architectural marvel is characterized by its distinctive, boldly spreading A-frame roof. This innovative design not only provides a striking visual appeal but also serves a crucial functional purpose: it acts as an effective thermal buffer. The double-layered pitched roof and extended eaves significantly minimize direct solar heat gain, ensuring the interior spaces remain cool and comfortable, while also casting broad, inviting shadows over the living areas below. The use of natural materials like wood, glass, and steel further enhances the home's connection to its environment, reflecting a commitment to sustainable and integrated design principles. Photography for the project was expertly captured by Quang Dam.
The vision behind Casa 9 transcends mere aesthetics; it aims to profoundly influence the way modern families interact with their environment. By emphasizing natural elements and thoughtful design, the house encourages a lifestyle that is both connected to nature and conducive to well-being. This project serves as a compelling example of how innovative architectural solutions can address contemporary needs for comfort, sustainability, and a deeper appreciation for the natural world.
