Let's take a closer look at some of the 'tropical' residential architecture pointed out in the 2007 Orange County Register article. While not all of the homes are tiki or Polynesian, they are definitely exotic and make a bold statement.
The first two neighborhoods (A & B) are quite near each other.
The 'A' neighborhood:
3142 Killybrooke Lane (built 1963)
A subtle design with a purely decorative A-frame and extended roof lines. The garage roof hangs over the front door entrance and is supported with a nice privacy screen.
The house adjacent is currently listed for sale at $575,000. I don't know how that price relates to the real estate market in SoCal, but that's quite a bit of change for a small house.
3160 Sharon Lane (built 1963)
The two different roof angles for the second story and the garage make this house quite unique. If it was repainted from this grey color scheme, it would be very unusual.
The ornamental detail that hangs over the garage is not a design I have seen before.
1284 Londonderry Street (built 1963)
This house is the same design we found along Killybrooke Lane, but in a different color scheme.
A few more details from around the neighborhood.
I forgot to write down the address of this home, but it is in the neighborhood (somewhere).
