After 30+ years in retail and commercial construction, I retired to specialize in the construction of custom homes. Established in 1997, Warren Johnson Custom Homes builds a limited number of homes each year. This allows me to personally supervise every phase of construction, from initial discussion to move-in. Warren Johnson Custom Homes is not a mass producer of homes - each home is individually unique and built exactly to the client's specifications. Energy Star requirements. Every home is energy Tested and Certified.
