The lands of Craigend were part of the Barony of Mugdock in medieval times, but the estate was sold in the mid-17th century to the Smith family. John Smith was born at Craigend and became a merchant and the founder, in 1751, of booksellers John Smith & Son. John Smith built a plain house on the estate, but after his death, in 1816, his son, James Smith, incorporated that house in a much more ornate mansion. It was built by Alexander Ramsay, initially using designs by James Smith of Jordanhill, in what is described as Regency Gothic style.
