This style emerged in 1853 when Boston merchant Thomas Larkin relocated to Monterey, Calif. The style updates Larkin's vision of a New England Colonial with an Adobe brick exterior. The Adobe reflected an element of Spanish Colonial houses common in the Monterey area at the time. Later Monterey versions merged Spanish Eclectic with Colonial Revival styles to greater or lesser extents.
Larkin's design also established a defining feature of Montereys: a second-floor with a balcony. At the time one-story homes dominated the Bay Area.
In today's Montereys, balcony railings are typically styled in iron or wood; roofs are low pitched or gabled and covered with shingles--variants sometimes feature tiles--and exterior walls are constructed in stucco, brick, or wood.
