Horizon Office Complex
/2021
Three interlinked wings organise daylight-flooded floorplates around verdant courtyards, creating a campus that flexes with evolving tenant needs. Algorithmically placed anodised fins harvest breezes and shade glazing, trimming HVAC loads by 28% and propelling the complex toward WELL Gold and LEED Platinum benchmarks.

Timescales
A carefully phased 36-month rolling schedule delivered the three interconnected wings in overlapping 12-month construction sprints, enabling early tenant fit-out and revenue.
Wing A topped out at month 9 and was fully glazed by month 12, with Wings B and C following on staggered four-month offsets using shared tower cranes in rotation.
Systems commissioning and sustainability certification wrapped up in month 34, leaving a generous two-month buffer for tenant punch-lists before occupancy.
Objectives
Maximise long-term adaptability, achieve nearly 100% daylight autonomy, and secure WELL Gold certification while delivering a verified 28% HVAC energy reduction.
Integrate landscaped terrace breakout zones on every level and carve a pedestrian-oriented retail spine that re-stitches the campus into the urban fabric.
Provide a cloud-based digital-twin dashboard so facility managers can monitor performance and predictive maintenance alerts in real time.
Materials
A hybrid composite steel frame anchored to precast concrete cores supports a unitised curtain wall whose anodised aluminium fins were sized through parametric daylight and wind analysis.
Courtyard façades are clad in locally harvested cedar, and interior finishes deploy low-VOC linoleum flooring, recycled-PET acoustic panels, and rapidly renewable bamboo casework.
Rainwater captured from the expansive roof areas is routed to twin 150-cubic-metre cisterns beneath the plaza, supplying grey-water systems and drip irrigation.
Challenges
Pandemic-era design revisions introduced contact-free entries, higher outdoor-air change rates, and hybrid-work desk ratios, adding coordination complexity.
Unexpected archaeological remains uncovered during bulk excavation halted work for six weeks and forced rapid footing redesign to preserve artefacts in situ.
Co-ordinating three concurrent wings across two main contractors demanded an exceptionally strict BIM clash-detection protocol to avert geometry conflicts and delays.
