Baxt Ingui Architects is excited to share that our Carroll Gardens project is the first Certified Passive House Plus in the United States and North America!

This project was one in a series of Passive Houses completed by our firm alongside six contractors, three engineers, a number of Passive House consultants, and many environmentally conscious clients. Over the past two years, this focused group and collaborative effort allowed for a highly efficient process, ultimately resulting in a systematic approach that can lead others to Passive House Certification.

We'd like to thank everyone on the team for their creativity and hard work.
