This Eco-Friendly Home in Vietnam Features a Roof Top Herb Garden

From the edible green roof garden to rainwater harvesting and passive solar design the House of One Piece by 85 Design exemplifies Eco Friendly, Tropical Residential Architecture

Designed by 85 Design with the intention to be the “eco-friendliest home”, the 250 sqm, 3 bedroom home in Da Nang, VIetnam, was crafted for young couple and their two children.

It achieves its sustainability goals by taking advantage of natural energy sources to limit the use of fossil fuels and adopts water reuse strategies to reducing the use of water resources. The ground floor has one living room, a kitchen, one guest bedroom, a storeroom, and a laundry room. The kitchen and the living room are connected in an order to create big and flexible space, as well as to reduce the constructed area, and leave more space for the garden. All rooms face the garden through big transparent sliding windows, which help create the best ventilation for the house.

The worship room, working room, and two more bedrooms are located on the first floor of House of One Piece and face the garden. They are also equipped with slide windows to maximize the airflow, especially the air from the sea nearby. The difference between the first floor and the ground floor is, the first floor is equipped with shutter windows. This helps reduce the sunlight when needed.

On the rooftop, there are a small playground and an herb garden that produces enough vegetables for daily use. The herb garden uses non-toxic chemical which is safe for human and pet; it also uses a circulated watering system which automatically controls temperature and humidity; preserves and redistributes water from the rain. After four years, on the same concrete floor, the tree-planted area is in better condition than other areas. Non-tree areas have cracks on the surface which can lead to water leakage. As such, it is advisable for people to plant trees on their rooftops. It is not only better for the environment but also protects your construction.

As calculated, by taking advantage of natural light, planting trees for heat radiation reduction, and utilizing the automatically circulated watering system, the home has a 30% energy reduction use for lighting and air-conditioning. These solutions do not only save energy but also protect the construction from harmful factors of the environment. In conclusion, the architects hope to inspire other colleagues around the world to develop more projects like this and to change the awareness of future generations toward mother earth.
