Design Build at Compass, co-founded by Lyon Porter, Stephen McArdle, and Jonah Katz, blends award-winning design with encyclopedic knowledge of the market to deliver one of the most dynamic and creative alliances in residential brokerage. The founders have represented over $2 Billion across 1,500 closed transactions encompassing every asset type: new development towers in Manhattan, pre-war lofts in Brooklyn, multi-million dollar development sites, and penthouses including the storied Puck Building and The Parc Imperial Tower.
Offering best-in-class service to homeowners, renters, investors, and developers, the founders' innovative, design-focused approach adds superior value to any real estate transaction. Members have consistently shattered price per square foot records in all asset classes and rely on a deep personal referral network that has thrived on a shared trust and understanding between real estate advisor and client.
The founders' expansive resume in design — having been featured in Architectural Digest and many other design and hospitality publications — allows for a unique approach through every step of a real estate transaction, whether it be the design and pre-development of a condo tower, overseeing the gut renovation of an individual owner’s property, or staging a resale property to position it to sell at the highest price. The ability to wear many hats — top producing broker, developer, designer, hotelier, and social media expert — has firmly placed Design Build at the forefront of New York City's real estate landscape.
