FOCUS Natural and man-made elements are interconnected and part of systems within systems. The built environment alterns the natural systems that support us. The Integrated Design Lab’s intent is to take a holistic view of these interconnected systems and use this to bring pertinent and concrete solutions in the way we design for a better future. We act under the premise that a good design is one capable of addressing contemporary issues and faces the challenges of the surrounding context as well as it’s own internal drivers. The team is interested in the whole lifecycle of the built environment and how each phase brings specific opportunities to reduce the environmental impact whilst enhancing wellbeing and project outcomes.

SCALES We analyse the context to get the bigger picture, enlarging the scope of actions, shared benefits and opportunities. Systems thinking is applied allowing more relevant and holistic solutions. When we design a building, we care about the Urban Context, climates, future climate and microclimates (Small to Medium). When we design a precinct, we care about the surrounding area and natural infrastructure (Large to Extra Large).

METHODOLOGY From exploration to accuracy
We adopt the architectural exploration approach and the rigour of applied sciences. Between creation, exploration, assessment and acuracy, the Integrated Design Lab leverages Digital Tools capabilities to bring innovative solutions.

AMBITIONS Set the right drivers
We analyse and interrogate the context, the architectural intent and client expectations to formulate the right questions to the design team. When the pertinent questions are defined, Digital exploration is applied to weigh the different scenarios and define a path of success.
