Bill Gates, founder and chief software architect of Microsoft, is seeking permission to add an additional room to his $109,500,000 home on Lake Washington. Gates representatives said the home "was designed for a bachelor and is now occupied by a family that finds it "isn't fitting as they expected it to." A variance for the work was granted in January by the Medina Board of Adjustment, but the family has yet to apply for their building permit. City records say the family "found errors were made in the way the house was designed, and the way they expected to use the house has changed. The proposal addresses those limitations."
