Many Sarasota Modern homes are not easy to spot from the street as they have fairly un-assuming facades. However, as mentioned before, there are a few common features to look out for, like clean horizontal lines, a flat roof, floor-to-ceiling glass walls, and broad overhangs for providing shade.
More generally, with Sarasota School of Architecture homes, there is nothing superfluous or "extra, everything is clear and purposeful with most of the elements of the building's construction being "out in the open". Simple, open spaces with adjustable exposure provide ample light and easily ventilated spaces.
Additionally, if you find a building designed by one of these architects, then you may have a legitimate example of Sarasota Modern architecture: Paul Rudolph, Victor Lundy, Gene Leedy, Ralph Twitchell, Tim Seibert, John Howey, Jack West, Carl Abbott, Phillip Hiss, Mark Hampton, Phil Hall, Jack Jetton, James Padgett, Frank Folsom Smith.
One hidden tell of Sarasota Modern architecture is Terrazzo floors. These polished cement floors can sometimes be hidden under carpets or tiles. Look for signs of a Terrazzo floor in liminal spaces like closets or thresholds. These make excellent targets for restoration.
