With a facade suggestive of a Renaissance villa, this is one of Riverside and Avondale’s finest Mediterranean Revival style houses. It was designed by Marion Sims Wyeth, an architect from New York who became one of Addison Mizner’s chief competitors in Palm Beach. The original owner of the house was Helen L. Parrott. She was the widow of Joseph R. Parrott, the President of Henry Flagler’s Florida East Coast Railway. The cost of construction was approximately $34,000. An outstanding feature of the house is its wrought-iron ornamentation, including the entrance gate, balcony, awning support rods, and elaborate window grilles. Cast stone is used extensively in the consoles that decorate the eaves, around the main entrance, and on the bracketed window sills. The weathered stucco exterior and mission-tile roof are further components of the Mediterranean Revival style. From 1958 to 1965, the Unitarian Church occupied the building.
