Located in one of Hanoi’s densely populated neighborhoods, 3x16 House is a compact dwelling that combines a small family home with serviced apartments. The project responds to the city’s overburdened housing demand by proposing a modest yet efficient living model that balances private and rental functions within a limited footprint.
The building is divided into two distinct zones: the rental units occupy the first to third floors (including a mezzanine), while the family’s private home sits above. A central vertical core connects the serviced floors, while the upper residence is arranged as a standalone house with open spaces and diverse internal connections. A double-height void between the fourth and fifth floors enhances visual continuity and family interaction. On the top floor, the kitchen and worship space open to a rooftop vegetable garden, fulfilling part of the family’s daily needs.
The project introduces an alternative perspective on the spatial configuration of mixed-use residential typologies. By reinterpreting the relationship between private living areas and rentable service spaces, the design seeks to dismantle the conventional sense of isolation and monotony that often characterizes such hybrid programs.
