Mangan Residence (Tascodero Residence)
The first ICF house built in California. Designed by David Horobin and contractor Mike Mangan of Sun General Construction, it stands as a superb example of residential design using a combination of SmartBlock ICFs and SIP (Structural Insulated Panel Syatem) to create a highly energy-efficient building envelope that, after 35 years, still boasts utility bills of around $50/month.
