Minimalist Café Architecture: O Plant-based Thao Dien Cafe by xưởng xép in Ho Chi Minh City

The O Plant-based Thao Dien Cafe, designed by xưởng xép, stands as a refined example of minimalist café architecture, embracing subtraction over addition as its core design philosophy. Situated in a 93-square-meter garden plot in Thao Dien, Vietnam, the project transforms a quiet green space adjacent to an old home into a serene and communal café rooted in plant-based dining and spatial simplicity.

Subtraction as a Creative Process in Architecture

Rather than imprinting a bold architectural identity onto the site, the design process was guided by a deliberate restraint. The architects chose to preserve the garden’s inherent value, avoiding disruption of its balance by subtracting instead of building anew. The result is a space that feels more like a conversation with its environment than an assertion upon it.

What emerged was a thoughtful, iterative process where architectural volume was gradually reduced, seeking out the purest form. This act of subtraction emphasized the qualities already present: light, vegetation, texture, and openness. By peeling away excess and resisting the temptation to define space through rigid enclosures, xưởng xép achieved an architecture that dissolves into the background while subtly enhancing everyday life.

A Café That Flows Within the Garden

The café’s program seamlessly coexists with the existing garden, blurring the boundaries between domesticity and public space. The garden, once private, now serves both the house and the café in a shared capacity. This dual function creates a spatial fluidity where greenery acts not as decoration but as an active agent in the design.

Partitions and enclosures are reduced to implied elements. Openings, courtyards, and changes in material cue visitors to understand zones without physical separations. A sense of privacy is maintained through spatial gestures rather than walls, reinforcing the garden’s presence in every corner of the café.

Material Honesty and Lightness in Structure

Every material used in the O Plant-based Café contributes to its ethos of minimalist café architecture. Columns, gutters, and roofing were refined to their bare essentials, expressing structure rather than hiding it. The undulating metal roof mimics the form of a drifting cloud, offering shelter while allowing dappled sunlight to filter through—softening the line between architecture and atmosphere.

The partitions are constructed from 3mm weathered steel sheets, bent along the edges for both structural reinforcement and aesthetic softness. These handmade elements evoke the texture and tone of aged timber, grounding the space in tactile familiarity while remaining contemporary. The façade, composed of steel mesh, lightens the visual weight of the building and allows for unobstructed interactions between interior and garden.

Architecture as a Soft Intervention

Rather than dominating the garden, the architecture of the café becomes an understated presence—an enhancement rather than an imposition. This subtlety transforms the space into a place of quiet retreat, offering a soft transition from old to new, house to garden, individual to community.

The result is not just a café, but a redefinition of how we think about small-scale architectural reuse. xưởng xép’s project embodies a forward-thinking approach to sustainability, where architecture works with the site rather than against it, allowing for new functions to grow organically within existing frameworks.

A Minimalist Café Rooted in Context

In an urban context like Ho Chi Minh City, where development often means replacement, the O Plant-based Café offers an alternative model—one that respects what already exists and improves it subtly. It shows how minimalist café architecture can respond to the environment, material culture, and human scale, all while creating spaces of comfort and community.

By eliminating the unnecessary and emphasizing presence through absence, xưởng xép has created a café that feels timeless—an elegant synthesis of restraint, nature, and architectural intent.
