Ryall Sheridan Carroll Architects is a New York City based architectural design studio with past and current projects in NYC, Long Island, Upstate New York, New Jersey and Vermont. Our work responds to the context of each project including landscape, neighboring buildings, climate and the end users specific needs. We work collaboratively with our studio team, consultants, clients and communities to provide the most fitting solution to each and every project.

Passive House

  • All of our projects incorporate strategies for implementing environmentally-friendly, sustainable design. In order to provide a shared knowledge base in the office, all designers are encouraged to take the course and exam to become a Certified Passive House Designer. We have designed multiple certified Passive House buildings, starting in 2012, and all of our designs implement Passive House strategies so as to reduce the energy load of the buildings and produce more comfortable space to live and work.

We start on our projects by working with models and sketches to develop designs while paying particular attention to the site, the context and the requirements of the client. At the same time, Passive House design principles are a central focus of our design development. Hardline drawings and 3D renderings are then produced while working collaboratively with the client, consultants and contractor. We are involved in the design at all scales, from site planning to custom hardware.
