Red and yellow create a playful dynamic in this dining room by architect and designer Alan Wanzenberg, who is based in Manhattan.

Dark furnishings and art anchor this sitting area.

This dining room is set in a trapezoidal nook with floor-to-ceiling windows.

Light streams into this sitting area from a large window on the left.

Wanzenberg restored and expanded this Hamptons residence, adding the breezeway that now serves as the primary entrance.
