Tropical Modernism in Vietnam — The Current Landscape

# Tropical Modernism in Vietnam — The Current Landscape *By TropMod Editorial* --- In the early mornings of Ho Chi Minh City, before the humidity settles like a second skin and the motorbike chorus reaches its crescendo, there is a brief window when the architecture of this metropolis reveals its truest self. Sunlight slices through the brise-soleil of a 1960s apartment block on Nguyen Dinh Chieu Street, falls in geometric bands across a terrazzo staircase, and catches the edges of a bougainvillea spilling from a third-floor balcony. This is Vietnamese modernism at its most unselfconscious — a vernacular that was never meant to be a museum piece, but rather a living, breathing response to one of the most demanding climates on the planet. Sixty years later, a new generation of Vietnamese architects is asking the same question that animated their mid-century predecessors: how does one build beautifully, affordably, and intelligently in the tropics? The answers emerging from Ho Chi Minh City, Hanoi, and Da Nang constitute one of the most vital architectural movements in Asia today. ## The Long Arc: From Colonialism to Contemporary To understand Vietnamese tropical modernism, one must first acknowledge the architectural palimpsest upon which it is written. French colonial rule (1887–1954) imposed European neoclassicism upon the Vietnamese landscape — the Hanoi Opera House, Saigon's Notre-Dame Cathedral, the ochre-washed villas of District 3 — buildings that treated the tropics as an inconvenience to be overcome rather than a condition to be embraced. Deep verandahs, louvred shutters, and elevated ground floors were concessions to climate, but the underlying proposition remained: civilisation meant Europe, and Europe meant thick masonry and steep pitched roofs, however unsuited to 35 °C heat and monsoon rains. The mid-century moment — roughly 1955 to 1975 — produced something altogether more interesting. In the south, Vietnamese architects trained in France, the United States, and Australia began synthesising Le Corbusier's Five Points with indigenous spatial logic. The result was what architectural historian Mel Schenck has termed "Southern Vietnamese Modernist Architecture" — a body of work encompassing hundreds of buildings that adapted the International Style to Southeast Asian conditions. The Independence Palace (Ngo Viet Thu, 1966), the General Sciences Library, and countless apartment blocks and private villas deployed deep overhangs, perforated concrete blocks, open stairwells, and rooftop pavilions — what Schenck has called a genuinely "vernacular modernism" that belongs as much to the Vietnamese builder as to the European theorist. Then came 1975, reunification, and the long lean years. Construction slowed to a crawl. Many architects fled or were sent to re-education camps. The subsequent Đổi Mới reforms (1986) gradually reopened the economy, but for nearly two decades, Vietnamese architecture was dominated by what one Hanoian practitioner charitably calls "the era of the developer": speculative construction with little concern for climate, context, or quality of life. Glass curtain walls, sealed air-conditioned boxes, and faux-European pastiche proliferated alongside rapid and largely unplanned urbanisation. The turning point arrived around 2006. Vo Trong Nghia — freshly returned from graduate studies in Japan — founded VTN Architects in Ho Chi Minh City. That same year saw the emergence of a cohort of young firms determined to reclaim Vietnamese architecture from both the colonial hangover and the developer's spreadsheet. What distinguishes this generation is not simply talent or ambition, but a shared conviction that architecture in Vietnam must begin with the climate. ## What Makes Vietnamese Tropical Modernism Distinctive Tropical modernism is, of course, a global phenomenon. Brazil produced Oscar Niemeyer's sensual curves and Paulo Mendes da Rocha's brutalist honesty. Sri Lanka gave us Geoffrey Bawa's courtyard-centric, landscape-led compositions. Thailand has seen a sophisticated blend of traditional teak architecture and contemporary forms. Each tradition has its own inflection. Vietnam's contribution to this conversation is distinctive in several respects. First, it is marked by an almost obsessive engagement with vegetation — not as decoration or afterthought, but as a structural component of the building's environmental performance. When Vo Trong Nghia speaks of his "House for Trees" series, he is not deploying a metaphor. These buildings are designed around the idea that the tree, the balcony garden, and the green roof are as essential to the dwelling's function as its concrete frame. The vegetation shades, cools, filters, and oxygenates. Second, the Vietnamese approach is characterised by an extraordinary density of innovation on very small sites. The "tube house" — a typology born of the feudal-era tax system that calculated property tax by street frontage — produces plots as narrow as three metres wide and twenty metres deep. These constraints, which would paralyse architects in most countries, have become the crucible of Vietnamese creativity. The result is a succession of vertical gardens, double-height voids, light wells, and interconnected courtyards that turn spatial limitation into spatial richness. Third, the materials palette is emphatically local. Where Lina Bo Bardi in Brazil was drawn to concrete's plasticity and Bawa in Sri Lanka to stone and timber, the Vietnamese practitioner gravitates towards brick, bamboo, laterite, and ceramic. Tropical Space's Termitary House in Da Nang (2014) is perhaps the most celebrated expression of this tendency — its double-skin brick facade functioning simultaneously as structure, thermal mass, and a breathing mechanism that allows the building to self-regulate its internal climate. Fourth, there is a philosophical dimension that separates Vietnamese work from its regional counterparts. The Brazilian tradition is animated by a Promethean confidence in form; the Sri Lankan by an almost Buddhist dissolution of the building into the landscape. The Vietnamese sensibility — informed by Confucian and animist traditions as well as a socialist emphasis on collective benefit — tends towards modesty, practicality, and a quiet conviction that architecture's primary duty is to serve the quotidian lives of ordinary people. The most ambitious Vietnamese houses are rarely statements of individual virtuosity; they are arguments for a better way of living together. ## The Urban Crucible: Three Cities, Three Conditions Vietnam's architectural renaissance is inseparable from the specific challenges posed by its urban centres. **Ho Chi Minh City** (population approaching 14 million) is the engine room. The former Saigon is dense, chaotic, entrepreneurial, and losing green space at an alarming rate — the city now averages less than 0.5 square metres of public parkland per person, one of the lowest ratios of any major metropolis. This deficit has been a driving force behind VTN Architects' "House for Trees" programme and similar initiatives. The city's mid-century modernist stock — under threat from development pressure — is also being rediscovered through the work of photographers, researchers, and preservation advocates. **Hanoi**, by contrast, moves more slowly. The capital's architectural DNA is a complex stratification: ancient temples, French colonial boulevards, Soviet-era apartment blocks, and the intimate chaos of the Old Quarter's tube houses. Density here is no less acute, but the presence of lakes, mature trees, and a stronger regulatory hand produces a different architectural response. H&P Architects — founded in Hanoi by Doan Thanh Ha and Tran Ngoc Phuong — has pioneered an approach they call "Agritecture", which integrates agriculture directly into the building fabric. Their Tropical Flow house (2023) in Dong Anh district treats water, vegetation, and living space as a single ecological continuum. **Da Nang** occupies a middle position. Smaller, more manageable, and bookended by mountains and sea, the city has become a testing ground for a more resort-oriented strain of tropical modernism. KeGa Villa by T3 Architects (2025), set between the ocean and a national park near Ke Ga, exemplifies this register: climate-responsive without being austere, contemporary without being rootless. The city also hosts some of Vietnam's finest examples of the perforated brick aesthetic — a technique that Tropical Space has elevated to an art form. ## The Architects Leading the Charge **VTN Architects (Vo Trong Nghia).** Founded in 2006, VTN has grown from a boutique practice into Vietnam's most internationally recognised architecture firm — and for good reason. Nghia's training in Japan (Nagoya Institute of Technology, then the University of Tokyo) infused his work with a rigour and material curiosity that set it apart from the Vietnamese mainstream. The firm's bamboo structures — including the Castaway Island Resort, the Wind and Water Café, and the Grand World Phu Quoc welcome centre (completed with 42,000 bamboo culms) — have established bamboo as a legitimate structural material in contemporary architecture. Equally significant, however, is VTN's residential work: the Stepping Park House (2018), the Binh Thanh House (2013, in collaboration with Sanuki + Nishizawa), and the House for Trees series represent a sustained attempt to reinsert nature into the dense urban fabric of Ho Chi Minh City. **H&P Architects.** Hanoi-based and socially engaged, H&P has carved a distinctive niche at the intersection of architecture, agriculture, and disaster resilience. Their "Blooming Bamboo Home" prototype — a modular, flood-resistant dwelling built from bamboo, thatch, and recycled materials — addresses the reality of a country where 70 per cent of the population lives in coastal and low-lying delta regions vulnerable to typhoons and sea-level rise. Flying Vegetation (Hue, 2022) and Tropical Flow (Hanoi, 2023) extend the same ecological intelligence to residential architecture, treating the facade as a living, filtering membrane rather than a static boundary. **Tropical Space.** Founded in Ho Chi Minh City by Nguyen Hai Long and Tran Thi Ngu Ngon, Tropical Space has become synonymous with an expressive, sculptural use of brick. The Termitary House (Da Nang, 2014) remains their signature project — a compact dwelling whose perforated brick envelope functions like the wall of a termite mound, regulating temperature and humidity through natural convection. Their subsequent work — the Terra Cotta Studio (Quang Nam, 2016), the Terra Cotta Workshop (2023), and the Happy Box (2020) — has deepened this exploration of brick as a material capable of being simultaneously structural, climatic, and aesthetic. The Nha Be House (Phu Xuan, 2022) demonstrates how the studio's approach can produce intimacy at modest scale. **MIA Design Studio.** Founded in 2003, MIA Design Studio is one of Vietnam's most versatile practices, with a portfolio spanning hospitality, residential, and public projects. Their Louvers House (Thu Duc, 2018) remains a textbook example of tropical shading — a facade of adjustable vertical louvres that transforms a conventional townhouse into a responsive environmental instrument. The firm's Sky House, Pure Spa at Naman Retreat (Da Nang), and Binh Thuan House (2022) demonstrate a consistent preoccupation with the threshold between inside and outside. **Sanuki Daisuke.** The presence of a Japanese architect on this list is not incidental. Sanuki, who trained at the University of Tokyo and spent formative years working with Vo Trong Nghia on the Binh Thanh House, has established his own practice specialising in the small-scale, finely-detailed projects that define the Vietnamese urban condition. His Apartment in Binh Thanh (2016) — a seven-room rental apartment that deploys open corridors, planted terraces, and a facade of perforated brickwork — demonstrates what can be achieved on a typical Saigon alleyway plot with intelligence and care. Sanuki's work represents an important bridge between Japanese precision and Vietnamese informality. ## The Green Imperative It would be a mistake to view the greening of Vietnamese architecture as merely aesthetic preference. The country is among the most climate-vulnerable on Earth. Rising sea levels threaten the Mekong Delta, home to 17 million people. Typhoons are increasing in frequency and intensity. Urban heat island effects in Ho Chi Minh City and Hanoi routinely push temperatures several degrees above surrounding rural areas. Vietnamese architects are responding with strategies that go well beyond token green roofs. H&P Architects' "Agritecture" concept treats the productive landscape as a building system — edible plants, aquaculture ponds, and composting cycles integrated into the daily functioning of the dwelling. VTN's Urban Farming Office (2022) in Ho Chi Minh City wraps a conventional office building in a hanging garden of fruit, vegetables, and native species that cool the facade and provide produce for the staff canteen. Tropical Space continues to develop the perforated brick facade — a low-tech, low-cost passive cooling strategy that requires no mechanical systems and no electricity. The government, for its part, has begun to take notice. Vietnam's Green Building Council (LOTUS) certification system, modelled on LEED but adapted to local conditions, has certified over 100 projects. The building code is slowly incorporating energy efficiency standards. But the real momentum comes from below — from clients who have seen what is possible and architects who refuse to accept the false choice between comfort, cost, and climate. ## Recent Landmarks The past five years have yielded a series of projects that suggest the movement is maturing rapidly. T3 Architects' KeGa Villa (2025) demonstrates that climate-responsive luxury is commercially viable — the weekend retreat is organised around a central courtyard that channels sea breezes while a deep overhanging roof provides shade to all living spaces. CTA | Creative Architects' Floating House (2025), developed in response to the devastating storms that struck Vietnam that year, reimagines the amphibious dwelling for the twenty-first century. 23o5Studio's Bong's House (2024) in Ho Chi Minh City transforms a 2000s-era residence through comprehensive reconfiguration, proving that renovation can be as transformative as new build. Idee Architects' Tam Dao Retreat House (2023), set on a 2,000-square-metre hillside with a mature pine forest and mountain microclimate, represents the high-end of the vernacular-modern spectrum — a house that disappears into its landscape rather than imposing upon it. The proposition, in sum, is this: Vietnamese architecture is no longer a regional curiosity or a post-colonial footnote. It has become one of the most fertile laboratories for climate-responsive design anywhere in the world. The constraints are real — rapid urbanisation, environmental fragility, limited resources — but so too is the energy and inventiveness with which Vietnamese architects are confronting them. If the mid-century modernists of Saigon asked the right questions, their twenty-first-century successors are beginning to provide the answers. --- *TropMod Editorial, May 2026*
