144 Vanderbilt is a condominium in Fort Greene, Brooklyn, clad in scalloped pink precast concrete. It steps in and out as it rises, producing private terraces, a sequence of open-air courtyards, and exterior hallways open to daylight.

9 Chapel is a condominium in downtown Brooklyn clad in undulating perforated aluminum panels that screen balconies and terraces while admitting light and air. The mass is broken into offset blocks, and the rippling skin is generated from just three panel types mixed across the elevations.

A slim limestone residential skyscraper in Manhattan's Sutton Place, and architect Thomas Juul-Hansen's first tower. Set among the low-rise pre-war buildings along the East River, its angular metallic crown shifts from gray to gold with the light.

A mixed-use housing development on former industrial land in St. Louis's Mill Creek Valley. Its corrugated metal skin, drawn from the surrounding factory buildings, shifts in tone as light moves across it. A second-floor amenity deck holds a heated pool, an ovoid lawn, and outdoor dining.

A 15-story mixed-use tower at the south end of downtown Evanston, its residential mass bent into a shallow S-curve shaped by the street grid and the rail line. A three-story brick base holds street retail and a planted green roof terrace, with the tower lifted above on slender columns.

A luxury residential tower overlooking Forest Park where nearly every unit is a corner unit. The floor plate rotates and mirrors a single unit around a central core into an oak-leaf footprint. Stacked tiers splay outward, shading interiors from summer sun while admitting low winter light.
