Harlaxton House, Heritage villa at Munro Street, Harlaxton, Australia.

Harlaxton House is a low-set, single-storey stone residence at 6 Munro Street, Harlaxton, built on a hillside with views over the Toowoomba Range. The architect is unknown, and the house was probably completed by March 1870 for Francis Thomas Gregory and his wife Marion Scott Gregory.

Harlaxton House was built for Francis Thomas Gregory, an explorer, geologist and botanist, and his wife Marion Scott Hume; the architect is unknown. A letter of November 1869 mentions the house Gregory was building on the Range, and a son was born there on 28 January 1871. Gregory died in Toowoomba in 1888, and the Perrys bought the house in 1891 as a summer residence.

Harlaxton House was rented by Lord Lamington, eighth Governor of Queensland from 1896 to 1901, and a railway station on the Main Line was established at Harlaxton for him, his guests and staff. It is widely believed the Lamington cake was first created here. The house was named after Harlaxton Manor near the Gregorys' home at Farnsfield, Nottinghamshire.

Harlaxton House stands at 6 Munro Street in Harlaxton, on a hillside overlooking the Toowoomba Range. The sources record no visitor access, opening arrangements or maintained gardens, and the house has been mostly unoccupied since Dorothea Cook's death in 1982. Treat it as a private heritage-listed residence seen from the street.

A railway station on the Main Line was established at Harlaxton for the use of Lord Lamington, his guests and staff; the cake named after him is widely believed to have been created here. The house itself was rented by Lord Lamington, eighth Governor of Queensland, from 1896 to 1901.
