Year Built


Architectural Style

Midcentury Modern

The original owner of this house was Frederic “Fritz” Carlson, a son of the Frederic Hjalmar Carlson (who built the Altfillisch-designed home at 303 Upper Broadway and the duplex at 606 Vernon St.) and a nephew of Roy Carlson (who built the Altfillisch-designed home at 212 High St.).

The original house was considerably smaller than the current house. The primary family entry was off Spring St. to the right (east) side. The original flat roofs were pitched in the 1970s by the original owner’s son, Frederic “Reed” Carlson. In 1963-64, a carport (later enclosed as a garage) was added to the left (west) side of the house, and a great room was added to the front/middle, which in effect made the Mound St. door the family’s primary entrance. Later, another section was added to the right (east) side. The home retains its original broad redwood exterior siding and considerable natural wood on the interior walls and ceilings.
