We have designed a two-level vacation home on Rollins Lake Reservoir in Nevada County, CA. The modern mountain style home maximizes a north facing view overlooking the lake, while orienting for maximum solar electric potential. The home can achieve net-zero energy through on site generation of all electrical power needs. The colorful exterior uses fireproof low maintenance materials in a playful response for a recreational second home. The house is designed with both upstairs and down individual suites for rental of either when the owners are not in residence.
