Local studio ODDO Architects<\/a> has extended TH+ House in Vietnam<\/a>, organising a series of shared, flexible spaces around tall voids informed by the “social intensity” of Hanoi’<\/a>s urban alleyways.<\/span><\/p>\n

The project saw ODDO Architects<\/a> returning to the site of TH House, which it completed in 2021,<\/a> to expand it into a neighbouring 2.5-metre-wide plot for the client’s growing family.<\/p>\n

With a site accessible only via narrow pedestrian alleyways, the studio looked to treat these constraints not as limitations but as “opportunities for social and spatial richness”, it said.<\/p>\n

Informed by Hanoi’s urban alleyways, ODDO Architects created a stacked series of flexible spaces overlooking tall central voids, with the whole organised around a branched steel support painted bright red.<\/p>\n

“In Hanoi’s alley neighbourhoods, vibrant community life is shaped by daily interactions \u2013 shared tea, small businesses, street games, and spontaneous social exchanges,” said the studio.<\/p>\n

“This social intensity became a key premise for the design of TH+ House,” it continued. “Rather than stacking isolated rooms, the layout is conceived as a series of layered environments with varying degrees of privacy, allowing visual connections across floors.”<\/p>\n

On the ground floor, a new kitchen space, which sits alongside a bathroom and small courtyard, flows directly into a dining area within the footprint of the existing home. A wall of folding glass doors opens onto the adjacent alley.<\/p>\n

Above, a living room, tea room and new bedrooms are kept visually linked through the introduction of internal windows and a bean-shaped opening, creating connections between both the new spaces and back into the existing home.<\/p>\n

Each level connects back into the original TH House via perforated white-steel walkways, which enable natural light to filter through the interior. Exposed concrete floor plates and the central red-painted steel column support these walkways.<\/p>\n

“The central red steel column acts as both the structural backbone and the spatial organiser of the house,” the studio told Dezeen.<\/p>\n
