The stair came first.
D’Hierro’s first phase in this house was the curved interior stair railing, completed in 2021. It follows a sweeping run and had to hold that curve without the pattern fighting the geometry underneath it.
It also set the vocabulary. Proportion, visual weight, the handling of an arc—decided once, in a stairwell, and answered to by the exterior later. A first commission does not have to anticipate the whole house. It has to be worth coming back to.
