The early design stage of an 18,500 m² office programme on a dense urban intersection. The text below sets out the decisions taken before form, and the constraints each one came from.
Context and constraints
The site sits on the seam between two scales: a six-storey residential fabric to the north, and a wide boulevard to the south with a high-density commercial axis behind it. The first question was not which of the two to side with, but what kind of transition to build between them.
Zoning fixed the total floor area, while a skyline study capped the height. That meant the massing could not simply rise: every square metre gained would be borrowed from open space at ground level.
Splitting the massing
A single block put the residential fabric to the north in shadow for most of the day. The programme was split into two volumes, with a half-open courtyard between them that lets people pass from the boulevard through to the back street.
The split is not a formal preference; it is the outcome of the shadow study. The gap between the volumes also became the building public face: at ground level it reads as a passage rather than a lobby door.
Facade and shading
The south-west facade takes direct light through the afternoon, and with a high glazing ratio the cooling load climbed quickly. Instead of horizontal brise-soleil, vertical fins running the full floor height were used.
Fin depth is not constant across the facade; it steps according to the angle of incidence. From outside the resulting rhythm may read as a decorative texture, but its origin is entirely performance. From inside it gives light that shifts through the day without ever going harsh.
Floor plate strategy
In both volumes the core is pushed north. Stairs and wet areas collect on the shaded facade, leaving the whole of the usable area on daylit frontage.
The typical floor is planned as a column-free span. Where a tenant would place a partition was unknown at design stage; the plan treats that uncertainty as a starting condition rather than a constraint.
Before a tower proposes a silhouette to the city, it is described by what it does at ground level.
