Sanuki Daisuke Architects builds light-filled house on dense urban plot in Vietnam

Double-height glazed walls help draw light into NGA House, designed by Vietnam studio Sanuki Daisuke Architects for a tight plot in Ho Chi Minh City.

NGA House is surrounded by one to three-storey buildings linked by a web of narrow alleys, where adjacent houses cast shadows over one another and block views.

Sanuki Daisuke Architects filled the site with as large a volume as possible, then cut its corners according to sunlight studies that determined where light could effectively be brought in without overheating the interior.

“We envisioned this building as a three-dimensional garden, where the wind and sunlight travels constantly from the outdoors through every open entrance in the building,” said the studio.

Common areas between rooms have been merged into a single continuous space to avoid compartmentalisation. This space shifts between single and double-height as it moves up the house.

A total of five bedrooms, spread across each floor, are arranged around this central space, and are more enclosed to offer privacy.

The ground floor entrance and common area, a kitchen and dining space above, the living room on the second floor and a worship room on the third floor are all located in this single continuous space.

Large double-height windows on the north and south side bring light into this space. These also form the entrance and the other opening onto a small first-floor terrace.

Sliding windows allow these areas to be almost entirely opened up to the outdoors, such as at the rear of the house where a small garden has been added.

In the common areas, wall and floor finishes are carried in from the outside spaces to create what feels like a continuous flow through the space.

“Waterproof cement is applied to both the outer and inner walls, making a seamless transition from the outdoor space to the inside of the house,” said Sanuki Daisuke Architects.

In bedrooms and more private spaces, wooden floors and white wall finishes provide a contrast to the these living areas.

On the second floor, a walled terrace space leads up to a rooftop garden surrounded by a high parapet and planted with trees.

Sanuki Daisuke Architects has previously completed private homes in Ho Chi Minh City on similarly tight urban plots. A 2017 apartment block was clad with a perforated terracotta screen, and the 2016 Hem House featured patterned grills over its windows.
