This double-layered roof residence is situated on a narrow 4×17 square meter plot. The side facing the street is set back 5 meters, creating a front yard space. Along the street, a beverage vending table has been installed. The household consists of three family members, so the living area does not need to be overly large. To meet the client’s request for enhanced natural ventilation, a double-layer corrugated roof system was implemented. This design not only keeps the roof lightweight but also delivers excellent thermal insulation.
The air buffer created between the two roof layers significantly reduces hot air from entering the house via convection. On the ground floor, the living room’s front door can be fully opened, allowing the space to double as an extension for a beverage shop when needed. Additionally, a bedroom is located towards the rear of this floor, reserved for occasional visits from the homeowner’s mother.
At the heart of the residence lies a courtyard that extends through all three floors, illuminated naturally by a semi-transparent roof. A poplar tree is planted in the courtyard, around which the staircase spirals upward, forming the green core of the home. The master bedroom on the second floor features a large bay window overlooking the atrium and study area.
To optimize living space and offer a dedicated entertainment area for the residents’ sons, their bedrooms, study rooms, and living rooms are distributed across different floors. This staggered arrangement creates offset balconies on the front facade, adding visual interest and enhancing the living experience.
Though simple in concept, the double-layer roof design effectively establishes a microclimate within the residence. It has proven to provide excellent heat insulation and a refreshing coolness during Vietnam’s hot summers.
