Custom infill home developer puts five more vacant lots on the market in Shaker Heights Thomas Jewell, cleveland.com SHAKER HEIGHTS, Ohio — Custom home builder Keystate will pursue marketing and development of five vacant lots around the city as infill housing prospects. The request approved by council last month came on the heels of the Pepper Pike-based developer’s first and successful foray into the city, in which a vacant lot on Fairmount Boulevard was marketed and sold. While working on the option to purchase that lot, Keystate officials identified other potential buyers, prompting their latest request for one-year options to purchase those properties for $1 apiece should more interest arise.
