Riverwalk is a compact “pocket neighborhood” of 13 Net Zero possible homes, carefully designed with details and systems that enable energy-conscious residents to have all of their daily energy needs met by renewable, on-site solar collection. The market-rate cottages each feature 2 or 3 bedroom layouts and range from 1,340 to 1,760 sf. Building upon a site plan concept developed by celebrated cottage neighborhood planner Ross Chapin, Union was asked by the client to refine and expand the initial masterplan while developing the aesthetic and details for the Net Zero cottages themselves.
