In partnership with Redmellon, this project received the National Trust Historic Preservation Secretary’s Award for the renovation of twenty-six historic single- and two-family houses in the neighborhoods of Seventh Ward and Treme. Innovative construction methods approved by the National Park Services (NPS) were used in order to create energy efficient structures while still preserving historic components of the original houses. This new closed-cell spray foam method is now being used as a case study precedent by NPS at a national level. The project complies with Louisiana affordable housing tax-credit requirements, including sustainability requirements of Enterprise Green Communities. Construction of all twenty-six affordable homes was finished in the summer of 2014.
