Stepping Park house in Ho Chi Minh City is a landmark project for Vo Trong Nghia Architects, a Vietnamese firm with a reputation for green buildings. The site is adjacent to a park and therefore lends itself particularly well to a design that extends the green space into the home itself.

A diagonal “void” cuts through the three floors of the house serving as a living room on the ground floor and a family room on the top floor. Additional overhead louvres provide shade for the top-floor space. The void is surrounded by a façade on which ivy is encouraged to grow and trees, planted in the openings in the façade allow natural light in while providing shade, cooling air, and beautifying the view.

Apart from creating spaces where indoors interfaces with the outdoors, the diagonal void cools the building thanks to the chimney effect. Vo Trong Nghia Architects says that this will reduce the building’s energy use as less electricity will be required for cooling.

Creating “Pockets of Park” Like Stepping Park House

The company says that the design optimizes natural ventilation and creates constant air movement that draws air through the building from the ground floor to the upper floor. The vegetation of the green façade will have an additional cooling effect thanks to shading and will also help to trap dust and pollution. Vo Trong Nghia Architects believes that its diagonal chimney concept could become popular as an energy-saving strategy in tropical housing design.

In addition, the architects note that the shortage of green space in Vietnam’s cities presents an urgent challenge they believe can be mitigated by creating “pockets of park” in private houses and public buildings across cities. Stepping Park House is the latest in the “House for the Trees” housing series developed by Vo Trong Nghia Architects.
