HCCH Studio Wraps Two Stalled Black-Box Theatres on Shanghai's West Bund in Aluminium Mesh and Fins

Shanghai's West Bund has spent the past fifteen years turning its industrial riverbank into a run of museums, theatres and plazas. Not every piece of that plan arrived on time. On the former site of the Shanghai Cement Factory, two black-box theatre buildings were left unfinished for roughly a decade. HCCH Studio has now completed BLDG1 and BLDG3 of the West Bund Dream Center. The scheme retains the original structure and repurposes both buildings as a 20,923 m² cluster of bars, retail, offices and a live music venue. Together they form what the architects call a nightlife threshold to the wider Dream Center.

The interesting part is how little the studio chose to do. The team set out to get a large effect from small interventions, and they said openly that they wanted to allow some chaos and spontaneity. The alternative was a clean modernist reset. The result sits somewhere between laissez-faire and careful control. The skins are aluminium only, the windows come from a low-cost system, and the billboards the planning authorities insisted on keeping stay in place. We think that tension is worth studying. It is a realistic model for how much of urban China will actually be remade: through edits, not erasure.

A Decade-Old Shell, Re-Dressed Rather Than Replaced

The before-and-after pairing tells you most of the story. The original block was dark and closed, a solid perimeter built for theatres that never opened. HCCH kept the frame and swapped the attitude. The new envelope opens that perimeter up for permeability and transparency, and the ground floor now reads as a series of entrances rather than a wall.

Exterior stairs, painted yellow in places, carry movement up the outside of the buildings. The facade does not hide circulation behind a skin; it lets you see people climbing. For a nightlife program, that visibility is part of the advertising.

One Material, Many Textures

Restricting the palette to aluminium could have been a cost decision dressed up as a concept. It reads as more than that. Across the two buildings the metal appears as convex and concave panels, expanded mesh, staggered fins and arched cutouts. Each finish catches light differently, so the facades shift in tone through the day without adding a second material.

The midday shot is telling. Expanded mesh throws angled shadows onto itself and onto the round concrete column below, so the screen produces its own texture. At night, lit from beneath, the same mesh turns into a soft lantern. A single material doing both jobs is economical in the best sense.

BLDG3: Silver Panels and Golden Fins

BLDG3 carries the more layered of the two skins. Its base is a silver field of convex and concave aluminium panels. Over that sits a lightweight metal mesh with golden fins. Long horizontal windows and balconies face the city and the river. The fins filter those views without blocking them, so the balconies feel semi-enclosed, more porch than glass box.

The mesh unit is the quiet technical achievement here. HCCH designed it to fit the existing modules, window positions, insulation thickness and lighting. In other words, the new layer takes its dimensions from an old building the team did not draw. That is harder than it sounds, and it explains why the fins land so cleanly on a structure that was never planned for them.

BLDG1: Keeping the Billboards, Adding a Screen

Most architects would treat mandated billboards as a defeat. At BLDG1 the planning authorities required the existing signage to stay. HCCH responded by adding more media rather than less: a cantilevered 3D screen projects from the facade over the lawn. The building accepts that it is partly an advertising surface and composes around that fact.

We find this more honest than the usual approach of hiding commercial signage behind a refined screen that the tenants then cover in banners anyway. Here the billboards and the screen are part of the elevation from the start. An amber glass-brick wall at the base adds warmth at street level, where the screens are too high to matter.

Curves Borrowed from the Neighbours

BLDG1's envelope uses warm tones and gentle curves, and the reason is contextual: it relates the building to the adjacent theatre. Rounded corners and curved screens soften the block's irregular footprint. They also turn the facade toward the Event Plaza, which the north end of the project frames together with SHL's Dome Art Center and West Bund Grand Theater.

Where translucent curved mesh wraps the bookstore frontage, the screen sits close enough to the glazing that the shop interior shows through at dusk. The curve does social work as well as formal work, drawing passers-by along the edge rather than straight past it.

Platforms, Stairs and a Rebuilt Circulation

A building designed as a black box has no reason to connect its upper floors to the street. Bars and retail need exactly that connection. HCCH added platforms and stairs to link multiple levels and reorganised circulation so that upper tenancies are reachable from the plaza without a trip through a lobby.

The aerial view shows how escalators and stairs rise straight out of the striped granite paving. The plaza's dark bands direct you toward these vertical routes, which makes the ground plane read as wayfinding as well as surface.

Designing for the Night Shift

Bar, live house, retail: this program comes alive after dark, and the facades are clearly tuned for it. Pleated mesh hovers above slender lit columns, arched openings glow over planted seating, and the illuminated screen anchors the stepped plaza. The buildings look better at dusk than at noon, which is the correct priority for a nightlife threshold.

The lighting also explains the ambition to let in some chaos. Tenant signage, screen content and crowds will keep changing, and the aluminium layers are calm enough to absorb that noise without competing with it.

A Pedestrian Street Facing Stacked Boxes

On its east edge the project forms a pedestrian street opposite the colourful stacked boxes by Atelier Deshaus. Here HCCH turns down the volume. White paneled blocks with ribbon windows and perforated metal face the lane, with blue chairs on terraces and timber-topped benches in front of planted beds.

The restraint makes sense. With a lively neighbour across the street, a quieter elevation gives the lane balance, and the terraces add life at a human scale instead of through facade drama.

Plans and Drawings

The axonometric section of the double-layer facade is the key drawing. It shows expanded mesh screens held off the glazing on an aluminium frame, with the insulation panel and paving build-up drawn in sequence. The second layer is a separate system attached to the old envelope rather than merged into it. That separation is what makes the retrofit reversible and cheap to adjust.

The site plan clarifies the urban role. The irregular red footprints sit beside the circular ribbed roof of the Dome Art Center near the waterfront edge. The renovated buildings frame the plaza between existing landmarks rather than trying to become one.

Why This Project Matters

Chinese cities hold a large stock of half-finished buildings, stalled by shifting plans, finances or programs. The default responses are demolition or a full recladding that pretends the past never happened. The West Bund Dream Center offers a third path. Keep the structure. Accept the constraints, billboards included. Then spend design effort on one well-engineered layer and a better circulation system. It is a lesson in proportion: knowing which few moves will change how a building is used.

It also makes a case for tolerating mess. HCCH's stated willingness to let in some chaos is not a slogan here; the screens, signage and stair-heavy elevations prove it. The aluminium palette keeps that mess legible, while the plaza and lane work hard to keep people moving through. For a riverfront that has often favoured monumental cultural objects, a commercial building that is happy to be busy, lit and slightly unruly is a useful addition.
