Flat Pack, catalogue and pre-manufactured homes have a secret history in the Bay Area. Many homes were pre-cut and delivered to the job site to be assembled in a matter of days. From small 2 bedroom beach bungalows to spacious 2000+ square foot shingle houses that line the streets of Alameda, many homes were ordered from a catalog and assembled on urban lots where people still live contented lives. There were also local architects and developers that created pre-fabricated homes locally to be delivered and built in developments. This book explores this history, through local leaders, archives, historians as well real estate brokers, investors, agents and homeowners. Oakland, Alameda, Berkeley and the surrounding areas were architecturally developed and influenced by the modern concept of efficient assembly line building. The book also explores how that building was affected by redlining and race relations at that time.
