Sustainable Living Innovations (SLI) calls its modular scheme a “kit of parts” system, which employs pre-assembled wall and floor panels. It estimates that its system will reduce construction costs by 10%, and lower operations and maintenance costs by 20% to 30%.

303 Battery will have 15 stories and 112 units, with no parking and about 1,900 square feet of retail/commercial space on the corner of Third Avenue. Twenty-seven units will be affordable under Mandatory Housing Affordability requirements and the city’s multifamily tax exemption program. All units, identical within each stack, will be between 350 to 900 square feet.
