The Old Alley’s Way of Life: Architecture Office in Hao Sy Phuong, Vietnam

June 19, 2023

Called hutong in Beijing, lilong in Shanghai, soi in Bangkok, roji in Tokyo, golmok in Seoul and gang in Jakarta—alleyways are ubiquitous across Asian urban landscapes, each with their own spatial morphology and sociocultural composition.

Urban researchers have noted that alleys/lanes are important sites of daily activity, shaped by various forces to present a mix of the historic and contemporary vernacular. However, many such neighbourhoods face the spectre of large-scale city development, threatening to erode the spatial character and displace the residents.

In Vietnam, alleys are called ngõ and ngách in Hanoi, and hẻm in Ho Chi Minh City. One popular hẻm is Hao Sy Phuong, which dates back to 1910 in the Chinatown area of Cho Lon.

For more than a century, this alley has consisted of over 60 ‘tube house’ units in a two-storey configuration. Many Hoa Chinese features/ornaments—such as trellised windows and iron doors, double-flap shutters, amulets, tablets and altars near doorways—have remained for multiple generations.

Since the alley has never been gazetted as a protected heritage building despite its old age, its preservation till this day, with minimal changes to the structure, is a testament to how it is well suited to and beloved by residents—as well as visitors. The old alley’s charm has drawn flocks of spectators over the years, from hundreds of daily tourists to movie crews and couples doing pre-wedding photoshoots.

So high was the attraction that Hao Sy Phuong residents limited entry to strangers during the height of the pandemic. The number of visitors has since mellowed down to 10–30 per day, and residents welcome visitors with a plea to not disturb their privacy or litter in the area.


Tucked away from the bustle of the main street, life in the alley has been described as peaceful yet vibrant at the same time. It hosts a mix of people across ages and cultures: long-time residents have stayed there all their lives, with newcomers moving in since the past decade. While most of the units are used as residences, a handful of home businesses such as mini-cafés, drink kiosks and noodle shops support the neighbourhood’s livelihood and become places for gathering.

The two-storey buildings are oriented around a shared courtyard to catch wind and light. Notably, the lower and upper units are not connected through an internal staircase, but rather by shared stairwells leading to a continuous balcony on the upper floor. This balcony is also a place where residents grow potted plants, from bougainvillea to pomelo trees.

An open-air atrium connects between floors. This serves as main ventilation and daylighting ‘chimney’ for the long and narrow units. These conjoined features in the neighbourhood and house modules reflect togetherness as the community’s way of life.


The main challenge was to limit the construction impact on the structure, considering its old age. Therefore, the renovation retained the existing walls and only erected a new wall in the mezzanine area with lightweight materials to reduce the load.

The front part, which faces the connecting balcony and courtyard, maintains harmony with the old neighbourhood. The architects then inserted a second roof under the tin roof, reusing old tiles that they kept from the previous renovation.
