An Inclusive Building: The Rainbow Centre Extension

The question was how to innovate on this type to lend greater spatial variety and social richness, while improving its flexibility and retaining its legibility. Within the constraints of a modest 4-storey addition on a narrow site, the architects decided to re-conceptualise the courtyard as two volumetric, light-filled atriums to anchor the new building.  Each atrium has its unique sectional (and terraced) profile that is finely calibrated for human-scaled interaction and intimacy. Other programmed spaces like classrooms, art studios, offices then coalesce around these anchor atriums on a plan layout that roughly resembles an "8-shaped" donut.  

Traversing these light-filled spaces, I cannot help but be inspired by how the building hums with life at every corner. Parents linger at the ground floor cafeteria watching over their wards, social service professionals exchange quick chats in delightful bump spaces, students' artistic creations cover the walls - a gentle humanism infuses this building.  This flourishing microcosm-of-a-society demonstrates in real life the intricate relationship between physical architecture, its touchpoints and interfaces, and the resultant social life. It follows on the humanistic legacy of Herman Hertzberger, the Dutch architect who designed his architecture fir the social life of its users in projects like his Centraal Beheer complex. 

Over and above typological configuration and programme, good architecture inevitably requires another level of visual resolution that relies as much on the architects' aesthetic choices than on mere solution-based competence. The Rainbow Centre Extension over-delivers in this department as well.  A visual and formal choreography pervades this building, arising from subtle repetition and modulation across multiple scales - of structural bays, of floor slabs, of masonry units, of sun-breaker panels, among other building elements. This continuous shifting and stepping in equivalent ratios - but finely calibrated - creates a musical effect akin to a Bach choral cantata where a single theme repeated across different registers and groupings crescendos into a polyphonic chorus. Harmony ensues.  

I am in thrall of the visual texture and range enabled by a single repeated move. Take, for example, the building façade's modular rhythm that encompasses the full range from solid to void, and heavy to light. Modular pre-cast masonry blocks transition gradually to planar tectonic louvers and then culminate in light metal screens on the roof in a seamless visual rhythm on alternating modules. Additionally, subtle tonal differences of grey paint further articulate the volumetric reading of surfaces. This yields a façade that becomes a veil with varying degrees of enclosure , creating a goldilocks dance that is neither too enclosed nor too open, neither too heavy nor too light, but suspended in perfect tension.

Every imaginative detail in this building acknowledges the unspoken rules of reality and economy - from the light, floaty metal screens at stair landings that creatively interpret BCA handrail regulations to create a volumetric effect, to the precise setting-out of prosaic T5 light fixtures. Here is proof that even the most everyday, run-of-the-mill ingredients can be corralled to imaginative effect, creating an architecture that exerts a "Net Positive" for our commons and sense of greater good. Hats off to Plystudio Architects for pulling off this stunner - on a tight budget and a 2-person design team, no less.
