Our solution is a utilitarian structure that references the modular shed, yet is functionally tailored to meet the organisation’s needs over three levels. We retained the masonry perimeter, and inserted the new steel structure offset from side boundaries to maximise natural lighting. The design achieves a remarkably pure diagram, with 3m modules of function interspersed with single modules of light filled polycarbonate circulation zones.

The elongated shed’s sculpted form optimises key external views to the east and west. The southern chamfer complies with Rescode, ensuring solar access to the neighbours’ fruit and vegetable garden; the northern chamfer optimises the output of a 36kW solar array.

At the Hoddle St frontage, the authentic physicality of bricks and mortar epitomises a proud, 90-year corporate identity — and also the history and character of the Richmond locale. Gunmetal grey reinforces the industrial aesthetic. Meanwhile, the sleek lines of the upper floor silhouette hint in a different direction — the refinement of a parent company (McCorkell Brown Group) whose interests encompass high-end hospitality and a boutique distillery. As an urban gesture, the building offers new interest and engagement to peak-hour commuters navigating this infamous arterial.

Within, McCorkell staff benefit from a spacious, light-filled layout with large communal areas (indoor and outdoor). Openable windows and ceiling fans bring fresh air to every desk, while the two demarcated vertical circulation zones allow natural light to permeate. The solar array supplies all electricity — and a sensor drives the operation of mobile external louvres that provide both natural light and appropriate shade throughout the day. The site location, barely 100m from West Richmond Station, further reduces the company’s implicit carbon footprint.

Collaborative testing and design was crucial to a successful outcome. We engaged Finding Infinity to model design iterations for thermal performance and day-lighting. And we worked closely with McCorkell’s own technical fabrication experts to develop the west-facing shading device — a triumph of engineering and industrial design.

“We designed it, they built it.” Of course, the relationship between architect and builder is never this simple — especially when the client is the builder. And they certainly demonstrated their professional instincts when helping us distil our design down to its earnest essence.
