Question

What does a territorial house look like?

A Territorial-style house is a flat-roofed adobe block topped with a course of fired red brick and trimmed in crisp white-painted milled lumber. The defining features are brick coping along the parapet, sharp 90-degree corners rather than the soft adobe round, and vertically proportioned double-hung or casement windows. Window surrounds are white wood, often topped with triangular Greek Revival pediments. Porch posts are square and Victorian rather than the rough timbers of Pueblo style. The wall surface remains earth-toned plaster over adobe brick, preserving the Southwestern base. The style developed in the New Mexico Territory between 1846 and 1912 as American settlers arrived with milled materials.
