This house is one of the more distinctive buildings in the entire region. Built by Swedish immigrant John Vale at the lower western end of the plaza and sold to merchant Noah Cox in the 1870s, the two-story dwelling stands in the middle of its dual lot, originally flanked by walls to either side. Remnants of white plaster bands still remain along its front elevation, which is constructed of long, thin, dressed sandstone blocks, an unusual wall assembly in the region. Its hipped roof with dormer replaced the original chipichil flat roof in the 1890s.

Next to the Cox House, the garden wall of the Lino Ramírez Complex (c. 1880), at 701 Portscheller Street, culminates into a two-story building with a chamfered corner entrance in a simpler version of the traditional brickwork by the German master mason.
