The residence architect Cary Bernstein designed for Scott Croyle and his family is an exercise in hide-and-seek. Clever storage keeps the space clutter-free and lets the structure shine. In the entryway, drawers tuck under the mezzanine, niches hold artwork, and speakers are built in line with the cabinets.

The couple's daughter reads in the cozy nook just inside the front door painted in a vibrant blue from Benjamin Moore. Of the storage area below, Fredrik says, "In Sweden, there's always a place to sit and take off your shoes. This is a version of that."

Pozner credits Borowski with the idea to use a roller shade, purchased at the Shade Store, to close off the sleeping loft. The simple intervention, neither sound- nor lightproof, is sufficient to demarcate one “room” from another.

“Try to group uses and find solutions that solve multiple problems,” Borowski counsels. As an example, Pozner cites the idea of having the loft stairs double as clothing drawers. Though he eschewed a handrail, preferring a cleaner look, Pozner says that the slipperiness of the stairs “remains a work in progress. We had grooves, but they hurt my feet.” The pair are now looking into heavy-duty felt treads.

Throughout the kitchen and dining spaces, the ceiling is painted in Dulux Wellbeing green. This continues along the underside of the staircase to help accentuate its form. The cupboards beneath the stair are painted in a deep blue, with circular red finger pulls. The couple’s son, Mo, uses the small cupboard as a hiding spot. “You spend so much time thinking about people and how people will use the space,” says architect Catrina Stewart. “It’s amazing to walk in and often be surprised at how pieces are evolving as the kids grow up.”

A grille of walnut slats, designed by Syme and made by the local millworkers MCM, delineates the edge of a new stair with open treads made of hot-rolled steel. Tall Bulthaup cabinets mark the edge of the dining area; Evans, a mechanical engineer, had them custom-made to conceal heating ducts that vent almost invisibly through the top edge.
