Thecostoftheunnecessary

We define luxury as the precise absence of the unnecessary. That principle turns out to be one of the most effective sustainability strategies available to a studio, long before any technology is specified.

The cost of the unnecessary

Subtraction is a carbon strategy

The greenest square metre is the one that is never built. Before a single low-carbon material is specified, the largest lever a designer holds is simply drawing less: fewer partitions, shallower plans, less structure carrying less finish carrying less maintenance for less time.

In our own projects, the decision to leave a shell honest, to patch rather than clad, to expose rather than line, routinely removes more embodied carbon than the eventual choice of a recycled versus virgin material. Restraint compounds.

Clarity as a brief

A clear plan needs fewer corrections on site, generates less waste, and ages more slowly because there is less to date. Clients read this as calm; the building reads it as a smaller footprint.

The discipline is to ask of every element whether its absence would be felt. If the answer is no, its presence is a cost, paid in money, in carbon, and in the quiet the room could have had.

Takeaways

  • The cheapest carbon is un-built area and un-specified finish.
  • Restraint reduces waste, corrections and maintenance, not just cost.
  • Test every element by imagining its absence.
