The project brief called for a new boutique office and the
reconstruction of a pair of heritage-listed shophouses. WOHA was commissioned
only after their demolition to reconstruct the shopfront (up to 7.5m depth) in
accordance with Singapore's Urban Redevelopment Authority's conservation and
planning guidelines, and to design an entirely new, contemporary rear wing.
As the original floor levels with their low ceiling heights were
retained, the front end of the shophouses was deemed more suitable for meeting
rooms, while the service end accommodated a mechanised carpark. The idea was to
strategically lift up the open plan offices within the upper 4 floors where the
floor plate size is maximised, higher headroom is gained, better views are
enjoyed and more natural daylight is accessed from the sides. Every flat roof
area is also transformed into roof gardens with the attic featuring the
office’s recreational lounge from which unblocked panoramic views of Hong Lim Park
and PARKROYAL on Pickering Hotel can be enjoyed.
Unlike a typical internalised courtyard, the main design strategy
was to invert the shophouse typology by carving out valuable floor area to
create an externalised, urban, public pocket park at the very heart of the
office instead. A café, break-out areas and meeting rooms are organised around
this park, enjoying the greenery and light that it brings to the deep plan.
This public gesture further serves to reduce the intermediate scale of the
9-storey building to a more intimate, human scale at the pocket park below.
The
formal architectural language of fractal, triangulated geometry originated from
the need to comply with authority requirements of having splayed corners as the
building is bounded by three roads. This inspired a chiselled expression that
was carried through in both plan and elevation, taking the form of internal
angled walls and external slanted planes, revealing a concave curtain wall like
that of crystal embedded in the hollow lower strata of its atrium park space.
Shading was also built into the formal language by means of an integrated sun
screen within the curtain wall system and a series of perforated aluminium
panels.
