The restoration of Salisbury House, a historic building constructed in 1928 in Des Moines, Iowa, is described. The building took more than 5 years to create and cost nearly $3 million to build and furnish. The structure consists of both aged and antique materials and is a re-creation of an English manor in Salisbury, England. The design incorporates three distinct historical periods. The flint and stone portion represents Tudor times; the Gothic porch dates from the reign of King John; and the brick addition dates from the time of Charles I. The house is a major tourist attraction. The Salisbury House Foundation contracted a firm to revitalise the building envelope while retaining the uniform exterior appearance. The work was carried out carefully to achieve a look resembling the original structure. Brief details are given of the restoration of the stonework and the repair of the deteriorated mortar joints using a portland cement-slaked lime putty.
