cold lab Turns an Underused Corner of Guangzhou's Xinghai Concert Hall into a Seatless Listening Lounge for Dynaudio

Concert halls tend to be fully alive for a few hours a week. The rest of the time they sit closed, waiting for the next programme, the next ticketed audience and the next fixed seating plan. On the south side of the first floor of Xinghai Concert Hall in Guangzhou, cold lab has taken a previously underused 480 m² space and turned it into the Dynaudio Lounge. It works as a showroom for the Danish loudspeaker brand, and it also works as the informal counterpart to the hall it lives in. The lead architects were Zhiwei Ou, Jianxi Lai and Hongdi Lin, with acoustic consulting by Yosemine.

The project's value does not come from a single gesture. It comes from a clear argument about what a brand space inside a cultural institution should do. The lounge has no fixed seating. On ordinary days it behaves like a public living room with a coffee bar. During events it becomes a small concert venue, a salon or a listening session. The finishes carry most of the intellectual weight: timber battens, rough limestone and a gapped ceiling grid are treated as working acoustic components first and as decoration second. We think that inversion is what makes the interior worth studying.

A Lit Room at the Base of a Dark Building

Seen from outside at dusk, the lounge reads as a warm timber box set into the dark stone base of the concert hall. That contrast is useful. The heavy, angled host building signals formality and occasion, while the glowing ground-level room signals that you can simply walk in. The covered entry walkway, with its linear slatted soffit, starts the timber language before you reach the door.

Inside, the glazing keeps the subtropical planting in view: dragon trees, fan palms and broad leaves in the courtyard and along the terrace. The lounge never seals itself off from the city. For a room built around controlled sound, that openness to view is a deliberate choice. Acoustic discipline does not have to mean a windowless box.

The Main Hall as a Public Living Room

The existing perimeter was irregular, and cold lab solved it in a sensible way. The awkward geometry absorbs the support programme: brand display, a VIP room, an immersive listening room and the coffee bar all sit along the edges. That move leaves the centre as a clean, flexible main hall. It is the right priority. The irregular plan does not dictate the experience; it gets used up by the rooms that can tolerate odd shapes.

The fan of ceiling slats radiating over the hall gives the room a sense of direction without fixing an orientation. Café chairs, a lounge corner and a speaker plinth can be rearranged around it. A grey curtain and timber-clad columns quietly zone the space. With no rows of seats to define front and back, the ceiling does that job lightly, and only when the room needs it.

Finishes That Do Acoustic Work

Most showrooms treat material as atmosphere. Here each surface has a measurable task. The rough limestone wall surfaces diffuse reflections. The ceiling grid, with gaps opening onto a polyurethane acoustic layer behind, cuts reverberation. The timber battens, backed with acoustic felt, form a large diffusion surface across the main hall. Ribbed oak panels sitting between darker textured panels make that logic visible, and you can read the wall as a sequence of absorbing and scattering zones.

This matters for a speaker brand. A listening room that flatters the product with a good-looking but untreated volume would be a contradiction. By building the acoustics into the finishes and not hiding them behind them, cold lab makes the room itself part of the demonstration.

The Bar, the Records and the Daily Ritual

The slatted timber counter, set in a lit alcove beneath the baffle ceiling, is what makes the lounge work on days without a programme. Records sit on a backlit shelf behind the barista, and a speaker is mounted on the wall. Coffee and vinyl give people a reason to come in when nothing is scheduled. For a space meant to extend the concert hall's life beyond formal performances, that everyday draw is more important than any single event.

Small niches displaying record sleeves, a lone armchair under a slim light strip and high stools against vertical battens all build a domestic scale inside a civic building. The intimacy is intended. The lounge asks you to linger, and listening rewards lingering.

Thresholds, Corridors and Curtains

The circulation between rooms is handled with restraint: long timber-lined passages, slatted ceilings and sheer dark curtains at the end of the view. Curtains, with textiles from Kvadrat among the listed manufacturers, act as soft acoustic thresholds. They can be drawn to isolate a session or left open to let the main hall breathe into the corners. A door left ajar onto a bright room of chairs and a speaker shows the general approach. Sound and space are separated by degrees, and rarely by hard walls.

Rooms for Serious Listening

Around the open hall, the edge rooms raise the level of commitment step by step. The immersive listening room has a studio-grade surround system, ceiling speakers and floor monitors, and rows of oak chairs facing a screen. The VIP room pairs Hi-Fi equipment with tailored acoustic design in a private setting. Its round cove-lit ceiling sits over timber-framed armchairs, and glazed doors open to the courtyard.

The furniture from Karimoku and Ishinomaki Laboratory leans toward low, simple oak pieces that disappear into the timber envelope. The sourcing is Japanese rather than local, but the choice fits the brief: quiet objects that do not compete with the sound.

Speakers Presented Like Instruments

Dynaudio's products sit in slatted oak niches on low timber platforms, lit by small track spotlights. The display grammar borrows from the museum vitrine but keeps the speakers in the same acoustic environment as the visitor. You do not admire a speaker behind glass. You stand in front of one that could be switched on at any moment. That is a more honest way to sell an object whose real value can only be heard.

Plans and Drawings

The floor plan confirms the strategy: a central main hall with the bar counter, display zones along the edges, a pentagonal experience room and storage pushed into the leftover geometry. The section shows the sloped ceiling over the main hall and a semi-outdoor corridor that links the interior to the planted edge, which explains why the room feels both enclosed and porous.

Why This Project Matters

Cultural buildings across Chinese cities have plenty of square metres that sit idle between events. The Dynaudio Lounge offers a credible model for using them. Partner with a brand whose interests overlap with the institution's, keep the centre unprogrammed, and give the public a daily reason to enter. The concert hall gains an informal front room, and the brand gains a showroom with real cultural standing.

The broader lesson is about material honesty in interiors. cold lab's finishes look warm and crafted, but every one of them earns its place acoustically. In an era of brand interiors designed mainly for the camera, a room tuned for the ear first is a useful corrective.
