The Avero House is a two-story rectangular block with an open loggia on the southeastern portion of the lot.

The walls are made of coquina stone laid in roughly horizontal courses with lime mortar, which are plastered both inside and outside.

Although the house was apparently built around 1749, the first detailed information on its layout does not appear until a map from 1763, which depicts it as having a U-shaped floor plan.

[2] The Greek Orthodox Archdiocese of North and South America purchased the building in 1966 and restored the house to its 1730s appearance.
