The 2018 Hamptons IDA Winners: Small Space Design

For an art dealer looking to enhance the arrival experience at his Water Mill abode, Stelle Lomont Rouhani Architects designed a freestanding slab-roofed structure that functions as a carport, an entertaining lounge, and a pavilion for showcasing artwork. Floor-to-ceiling windows embrace the wooded surroundings, including a dense bamboo garden and pathway that leads to the main residence. “It’s chic and has good bone structure,” notes judge Janice Parker.

Clocking in at a modest 1,000 square feet, this shingle-clad Sag Harbor cottage contains a kitchen, powder room, and two bedrooms with en suite baths—thanks in large part to the Lacuna Project’s clever use of second-floor dormers that house the sleeping quarters. Judge Timothy Brown admires the “well thought-out” scheme, while judge Nathan Orsman describes the structure as “wonderful and compact—it has it all.”

The term “waterfront property” gains new meaning with this sleek two-story Bellport boathouse. The roof deck takes its cues from classic boat vernacular, while a galley-inspired kitchen features built-in mahogany seating and storage. To protect the structure from harsh elements, Martin Architects also incorporated a rain screen and steel doors. Judge Richard Keith Langham deems it a “wonderful waterfront hideaway,” while Parker praises its “clever and innovative” design.
