Den

Kartheiser’s private courtyard includes a covered seating area and fire pit, designed by Roberts.

The house may appear conventional at a glance, but a closer look shows how Oostenbruggen has pushed the boundaries of the traditional gabled typology. It has an asymmetrical roof, with slate shingles that extend down the eastern side to close it off completely.

The second-floor office is housed inside a rounded rectangle of concrete that the architect inserted on top of the old farmhouse.

Of the seven steps in Michael Pozner’s not-quite-500-square-foot aerie in Greenwich Village, five contain drawers. His small set of table and chairs is from CB2.
