Accessory Dwelling Unit Demonstration Project

AHL designed an Accessory Dwelling Unit (ADU) in collaboration with Appleseed Center for Law and Economic Justice to showcase a beautiful, sustainable and affordable housing alternative. The 340 SF, demonstration ADU, being built in Waimanalo, features all the essential elements of a single-family home and can be replicated on an appropriate site with minimal modifications. The ADU is sited on a half-acre Hawaiian Homelands lot, next to the existing 1,500 SF main house. The design incorporates the sustainability principles of the Living Building Challenge and will be detached from public utilities. General Contractor Hunt Moss Hawaii is collaborating with JOBCORP Hawaii and Honsador Homes to create an ADU framework that can be mass produced to reduce costs and employ local tradespersons. This affordable housing solution could be utilized by target audiences such as multi-generational families, young families, caretakers, or those needing to create a supplemental revenue source through rental income.
