exutoire renovates narrow tube house in hanoi<\/p>\n

\u00a0<\/p>\n

Exutoire completes 22YB1, a full renovation of an early-1990s tube house in central Hanoi <\/a>that now accommodates both the architects\u2019 studio<\/a> and a multigenerational home<\/a>. The project reworks a three-and-a-half-story structure measuring just three meters wide by 12 meters deep, a typical post-\u0110\u1ed5i M\u1edbi housing typology, to address long-standing issues of darkness, poor ventilation, and thermal discomfort.<\/p>\n

\u00a0<\/p>\n

Emerging in large numbers during Vietnam\u2019s construction boom of the 1990s, tube houses are defined by their narrow plots and deep plans, often resulting in dim and stuffy interiors. Exutoire reorganizes the core of the building and relocates the staircase<\/a>, previously positioned at the center and acting as a spatial barrier, to the back of the plot and removes transverse partitions to open up each level, allowing light and air to travel freely through the depth of the house. Larger, continuous rooms replace compartmentalized floors, and the new open stairwell contributes to improved cross and stack ventilation, a passive<\/a> strategy particularly relevant in Hanoi\u2019s humid subtropical climate.<\/p>\n

rethinking the tube house section<\/p>\n

\u00a0<\/p>\n

In keeping with the long tradition of shophouses in Vietnam, the ground floor functions as Exutoire\u2019s architecture studio<\/a>, while the upper levels host a form of non-nuclear living designed for family and friends. The arrangement reflects a hybrid domestic-work model embedded in the urban history of the city.<\/p>\n

\u00a0<\/p>\n

At the front, the architects recondition the facade while preserving traces of its previous expression, maintaining a layered reading of time. At the rear, a wall of glass bricks introduces diffused natural light deep into the plan while maintaining privacy in the dense urban fabric. New window openings and the repositioned stairwell enhance airflow, while the facade upgrade improves overall energy performance.\u00a0<\/p>\n

structural reinforcement and rooftop extension<\/p>\n

\u00a0<\/p>\n

The team selectively reinforces the original concrete column-and-beam structure with brick infill to make the structure more durable without erasing the existing framework. Above, a galvanized steel structure clad in insulated corrugated sheet metal forms a roof extension, signaling a contemporary addition while remaining materially straightforward.<\/p>\n

\u00a0<\/p>\n

Granito flooring, exposed concrete surfaces, and white-painted walls and ceilings, treated with varying levels of gloss, create a neutral backdrop. Within this restrained field, color operates as punctuation, with bright yellow ceramic tiles, royal blue oil-stained wood cabinetry, and lacquer-red cylindrical handrails animating the interior.<\/p>\n

\u00a0<\/p>\n

Bas-reliefs on the front facade mark the address and year of completion of the building, referencing a century-old local practice that acknowledges the rebirth of a house through architectural inscription.\u00a0<\/p>\n
