Sustainability is often presented as a list of technologies added to a building: panels, pumps and sensors. These matter, but they come second. The largest environmental decisions are made much earlier, when we decide how much to build, what to keep and which materials to use.
Question the brief
Many briefs ask for more space than a household or organisation will actually use. We spend time understanding how people live and work today, and we often find that well-planned rooms, generous storage and flexible spaces can reduce the area by ten to twenty percent without losing anything that matters.
A smaller building costs less to build, to heat and to maintain. It also leaves more of the site for planting, shade and water.
The most sustainable square metre is the one that does not need to be built.
Keep what is already there
An existing structure holds decades of embodied carbon. Wherever we can, we repair and adapt rather than demolish. At Atelier Marin, keeping the brick shell and the original trusses saved hundreds of tonnes of material and gave the studio a character no new building could match.
Survey existing structures before assuming demolition
Reuse stone, brick and timber recovered on site
Choose natural materials that can be repaired rather than replaced
Design for disassembly, so future changes do not mean waste
Passive first, technology second
Orientation, shade, thermal mass and cross ventilation do most of the work in a well-designed building. Only once these are right do we add heat pumps or solar panels, and then they can be smaller, simpler and cheaper.
None of this is new. Traditional buildings in every climate have always worked this way. Our job is to combine that inherited knowledge with careful modelling, so that every project uses less and lasts longer.
