Vari Architects Turns a Forgotten Chongqing Office Building into a Raw Concrete Cultural Hub

Chongqing is a city that builds on itself. Its steep topography forces architecture into constant negotiation with gravity, terrain, and the accumulated weight of prior construction. RICHAUS, completed in 2024 by Vari Architects, takes an overlooked office building buried within this layered urban fabric and repositions it as a public cultural anchor. The 8,000 square meter mixed-use project, led by principal architects Qi Fan and Jiang Yinan, doesn't erase the building's utilitarian past. It amplifies it, treating exposed concrete, raw beam structures, and visible infrastructure as the raw vocabulary of a new spatial identity.

What makes RICHAUS genuinely interesting is its refusal to finish. Where most adaptive reuse projects polish their host buildings into sleek containers, Vari Architects deliberately preserves a sense of incompleteness: rough concrete textures sit beside precision-milled timber cladding, fire safety cabinets and exposed conduit become designed objects, and a central multi-level atrium is threaded with interlocking steel staircases that function more like vertical public space than mere circulation. The result is a building that feels perpetually in formation, which is exactly the point for a program that hosts avant-garde brands, architecture studios, content creators, and public cultural events.

A Courtyard That Holds Its Breath

The exterior moves of RICHAUS are restrained but precise. A courtyard facade wrapped in horizontal metal louvers catches its own reflection in a still, dark water pool, creating a moment of near-silence in a city that rarely offers one. Elsewhere, a concrete entry volume is framed by perforated metal screen panels and recessed doorways, its severity softened by the deciduous trees that flank it. There's also what reads as a weathered rammed-earth surface, textured and layered, that gives the project an almost geological quality, as if the building grew from Chongqing's own hillside.

The facade strategy is not about a single material statement. Concrete, metal mesh, rammed earth textures, and glass pavilion insertions coexist, each responding to a different condition at the perimeter. The building doesn't announce itself from the street so much as it absorbs you, pulling visitors through a sequence of thresholds rather than delivering a singular entrance.

Concrete as Character, Not Canvas

Inside, the exposed concrete structural frame is the dominant presence. Beams and columns are left raw, their textures ranging from smooth to deliberately rough, creating a hierarchy of surfaces that reads like a geological cross-section. Against this backdrop, cylindrical columns are wrapped in warm timber slats, introducing a rhythm of tactile warmth that prevents the interiors from tipping into brutalist severity. The patterned floor tiles, gridded and geometric, anchor the ground plane with a precision that contrasts with the ceiling's roughness.

Hallways are not afterthoughts here. Timber-clad columns with integrated strip lighting, exposed ductwork running overhead, and linear ceiling fixtures turn corridors into inhabited spaces rather than transitional voids. A curved reception desk in one passage suggests that even the act of arriving at a particular floor is meant to feel like an event.

The Staircase as Vertical Commons

The central atrium is where RICHAUS makes its strongest spatial argument. Open steel and timber staircases weave between multiple levels, intersecting and diverging like a three-dimensional street network. Looking down from the upper floors reveals a vertiginous layering of steel rails, concrete beams, and timber panels. Looking up, the same elements compress into a lattice of structural and circulatory logic. This is not a grand stair meant for spectacle. It is a working connective tissue that makes the building's vertical dimension genuinely public.

The staircases cross over concrete pits edged in brass railings, rise through forests of exposed columns, and deposit you at landings framed by vertical slat partitions. The effect is one of constant visual connection between floors, a spatial generosity that encourages the kind of accidental encounter essential to any creative community building.

Details That Refuse to Disappear

Vari Architects clearly invested serious design attention in the elements that most projects bury or ignore. Metal balustrades with vertical fins and horizontal rails are treated as custom furniture rather than code compliance. A fire safety cabinet, typically hidden behind drywall, is encased in metal mesh and mounted beside stainless steel conduit with the care of a gallery vitrine. Timber handrails connect to steel brackets with a jewel-like precision that belies the project's rough overall aesthetic.

The approach transforms utilitarian objects, light fixtures, railings, conduit, fire hydrants, into active design participants. Nothing is concealed. The honesty of the infrastructure doubles as an aesthetic commitment: what you see is genuinely what holds the building together.

Framed Thresholds and Layered Views

Throughout RICHAUS, openings are composed with the deliberateness of a camera viewfinder. A curved aperture frames a timber-lined atrium with staircases and balconies receding into depth. A concrete portal reveals a timber volume beyond, with a cylindrical column and a wall-mounted light carefully positioned to catch the eye. These moments of framing give the building a cinematic quality, rewarding slow movement and deliberate looking.

The stair that crosses over a sunken concrete pit, edged with brass railings, is particularly effective. It compresses the viewer's focus downward before releasing it laterally through adjacent openings. The building is full of these spatial compressions and releases, a trick borrowed from Chongqing's own topographic drama.

Program as Ecosystem

The mixed-use program is organized not as a rational stacking of functions but as an interconnected network. Glass storefronts with folding doors open onto furniture showrooms. Glass-walled corridors look into planted display areas lit with studio lighting. At the building's edge, a concrete wall panel with engraved lettering sits between fluted metal cladding and a dark angular ceiling, marking the transition from public to semi-public territory. Each program element, whether exhibition space, design studio, or retail, is positioned to be seen from or through another.

The intent is clear: RICHAUS is meant to function as a creative ecosystem rather than a collection of tenants. The architecture does the heavy lifting of forcing visual and spatial adjacency, ensuring that the occupants, whether an avant-garde brand or a content creation studio, cannot fully retreat from one another.

Interior Atmosphere and Materiality

The overall interior atmosphere balances austerity with warmth. Fluorescent tube lighting, typically the enemy of architectural ambiance, is deployed deliberately here, its cool even glow complementing the raw concrete ceilings rather than fighting them. Timber slat balustrades in the stairwells soften the acoustic and visual harshness of the concrete frame. The multi-level atrium spaces, with their exposed columns, timber beams, and metal staircases, achieve a density of material expression that avoids clutter by maintaining a strict palette: concrete, timber, steel, glass.

There is a discipline at work here that deserves recognition. The temptation in a project of this scale and ambition is to introduce too many materials, too many gestures. Vari Architects holds the line, letting the building's original structural bones do most of the expressive work while adding only enough new material to make the space hospitable.

Plans and Drawings

The floor plans reveal the project's organizational logic: curved staircases flanking central voids, zigzagging circulation paths that prevent any single linear route through the building, and a column grid that structures the perimeter rooms while leaving the center open for communal activity. The elevations show the pavilion-like glass insertions at ground level set against the taller gridded facade behind, confirming that the building reads as two scales simultaneously, intimate at the street and monumental above.

The axonometric drawings are especially revealing. An exploded view shows three floor plates connected by a central spiraling stair, while a cutaway reveals how skylights at the top of the atrium wash daylight down through the building's core. The detail axonometrics of the stair assembly, with blue glass balustrades and walking figures for scale, show the degree of geometric precision involved in threading new circulation through the existing concrete frame. A balcony assembly detail, with steel grating panels and a sliding door system, demonstrates that the project's apparent roughness is backed by careful technical resolution.

Why This Project Matters

RICHAUS matters because it offers a convincing model for urban regeneration that doesn't rely on erasure or spectacle. In a city undergoing rapid transformation, Vari Architects chose to work with rather than against an existing building's bones, finding architectural expression in the honest display of structure, infrastructure, and material process. The decision to treat fire hydrants and conduit as design elements is not merely a stylistic choice; it is an ethical position about the value of what already exists.

More broadly, the project demonstrates that mixed-use buildings for creative communities need spatial generosity, not just programmatic variety. The multi-level atrium, the interlocking staircases, the framed thresholds between programs: these are architectural moves that no co-working app or tenant fit-out can replicate. They are embedded in the structure itself, which means they will outlast any single occupant. In Chongqing's mountain city landscape, where buildings are constantly negotiating their relationship to terrain and to each other, RICHAUS finds a way to be both rooted and open, both rough and precise.
