NYC Townhouse Design & Renovation

Your townhouse transformation demands both design vision and deep expertise - we bring decades of experience creating exceptional homes through both.

Every New York City townhouse tells its own unique story. While these iconic structures may present a uniform facade, each 20-foot-wide property contains its own set of characteristics, challenges, and possibilities. At k—da, we specialize in transforming these historic properties into sophisticated contemporary homes while navigating the complex matrix of structural considerations, regulatory requirements, and design opportunities.

New York City’s townhouses present a unique architectural challenge, each containing its own structural DNA and historical narrative behind its uniform facade. Every property demands a nuanced understanding of century-old conditions, neighboring structures, and the intricate matrix of regulations that shape its potential.

At k—da, we excel at weaving contemporary life into these historic envelopes through innovative design solutions. Our expertise in vertical circulation, light optimization, and systems integration allows us to transform complex renovation projects into exceptional homes that honor their context while embracing modern living.
