The project reserves 14 units as supportive housing and services for chronically homeless individuals and families at risk of homelessness with Project Based Housing Choice Vouchers. Of the 55 affordable units, 14 units are restricted to families earning 25 percent of the Area Median Income (AMI), 26 units between 30 percent and 50 percent AMI, and 9 units at 60 percent AMI. There are also 14 market-rate units as well. 340+ Dixwell has 26 one-bedroom, 33 two-bedroom, and 10 three-bedroom units. 340+’s mass timber/passive house with rooftop solar approach incorporates natural and healthy materials throughout the building interior, reduces its embodied and operational carbon footprint, and serves as a model to broaden the social, health, and economic potential of affordable housing construction.
