Final answer:
The Montage Laguna Beach is a resort, not a housing estate, so it does not have 'estates.' People residing in affluent California coastal cities like Santa Barbara, Laguna Niguel, and Carmel live in areas characterized by upscale properties with Mission Revival architecture.
Step-by-step explanation:
The Montage Laguna Beach does not have a specific number of "estates" in the traditional sense, as it is a luxury beach resort rather than a residential area. However, people living in upscale Coastal California cities such as Santa Barbara, Laguna Niguel, or Carmel are familiar with premium housing and the signature Mission Revival architecture that characterizes the landscape. These locations are accustomed to high-end living, often featuring a collection of extensive private homes.
That being said, it's important to note the history of the area, illustrated by events such as the 2005 Laguna Beach Landslide, where many homes, even those built with upscale standards like those in affluent coastal cities, were subject to natural disasters.
