Our portfolio spans multiple townhouse typologies and architectural styles, and we are recognized among the best architects in New York City for our all-encompassing townhouse-specialist and project management services. A townhouse renovation in the five boroughs is one of the most complex forms of residential construction - requiring deep expertise in building codes, zoning regulations, Department of Buildings and Landmarks Preservation Commission procedures, approvals and permits, structural design, building systems integration, energy efficiency, and construction coordination, among many other factors. We address, in detail, all the many factors involved and integrate them into a cohesive and unique architectural product which also articulates our clients’ specific desires and ambitions for each townhouse project.
In addition to the regulatory and technical challenges, each townhouse presents its own set of constraints and opportunities. Narrow lot widths, party wall conditions, vertical circulation, and limited access for construction all demand careful planning and precise execution. For landmarked properties, this complexity is further heightened by the need to preserve and restore historic fabric while integrating contemporary living requirements. Our work often involves selective preservation, full gut renovations, vertical and horizontal expansions, rooftop and cellar additions, and the reconfiguration of interior layouts to bring light and openness into dense urban conditions.
Our firm brings the comprehensive technical knowledge and design experience needed to navigate these challenges and deliver high-end New York townhouse design solutions with beauty, distinctiveness, clarity, and attention to every detail. From initial feasibility studies through construction administration, we guide each project with a rigorous, hands-on approach by our experienced team of architects - ensuring that design intent is fully realized and that each townhouse is transformed into a cohesive, highly tailored residence.
