The Leighton home was the house of Thomas and Martha Leighton on Planet Q. This home was located within walking distance of a town.
In 2266, the Karidian Company of Players was invited to the home by Doctor Leighton after a performance of Macbeth for a cocktail party. Sometime later, after his body had been recovered, from where he had been murdered, he was laid down on a couch in the home. (TOS: "The Conscience of the King")
