Sketch plans were prepared for the house before the end of February 1904 and tenders closed a fortnight later. Hodgen's first work on the site was in April 1903 when tenders were called for fencing. Sophia Holberton held title to the remaining two acres, which passed to Edwin Chisholm Bernays in 1916, following her death.

John Mundell purchased three acres, on which stood the residence. The Holbertons subdivided their property again in 1915. Title for the eight acres was transferred to Frederick Hurrell Holberton on 30 November 1888. James Williams purchased subs 21-23 of section two of portion 155, in March 1877, which comprised just over eight acres. Title passed to William Lord in October 1861 who later subdivided the property in 1877.

The grant comprised Portions 155 and 156, an area of just over 60 acres. The Deed of Grant for the land on which Tor was to be built was issued to Lucy Harriet Fletcher on 19 November 1860.

The residence was designed by Toowoomba architect, William Hodgen, Mrs Holberton's nephew and built by John Sweeney. Tor, a single storey timber residence, was constructed in 1904 for Mrs Frederick Hurrell Holberton.
