Linnwood, Heritage house in Guildford, Australia

Linnwood is an Italianate-style house at 11–35 Byron Road, Guildford, built on rising ground at the end of a long winding gravel driveway. It has a central portico flanked by French windows and segmented projecting bays, and its main house features stained glass windows and doors.

George McCredie, a builder and engineer, designed and built Linnwood in 1891 as a country home for his wife Susan and their nine children. The family moved from Glebe that year, and McCredie became a local alderman and mayor. He died at Linnwood in 1903, aged 44. The property later served as a truant school and children's home before becoming a historical society.

George McCredie established Presbyterian services in a hall on the property in 1894, and the gardens once held water fountains, a summer house, a schoolroom and that hall. The house is also known as Linwood Hall, Lynwood Hall and Guildford Truant School, names that record its later uses.

Advance booking is recommended as visits are arranged through guided tours organized on specific dates. The house sits in a quiet residential area and is most conveniently reached by private transportation.

Linnwood was the first property in the district connected to Sydney's telephone system, and George McCredie designed and built the underground cable tunnels that the network still uses. He also hosted Presbyterian services in a hall on the grounds from 1894, before a church was built in the township.
