Glendalough, Rosewood, heritage-listed villa in Rosewood, City of Ipswich, Queensland, Australia

Glendalough is a high-set timber villa on a corner lot at 96 John Street, Rosewood, built in two stages from about 1900 to 1911. Its roof has a central pyramid with a cast-iron crest and gables to the east and south. A front stair with crossed-timber balustrade turns out into the garden. An octagonal bedroom, 5.27 metres wide, projects from the northeast corner, and a large billiard room extends to the south.

Thomas Ernest Bulcock bought the John Street site in December 1910 and raised an £800 mortgage on it in March 1911, likely funding the flamboyant extensions. He and his brother Arthur ran Bulcock Brothers' The Trade Palace, a general store they bought from Frederick Lound around 1908. The Bulcocks sold the business about 1923–24, and the house passed to the Grant family in late 1923.

The house served as a gathering place for the local community and reflects the social standing of the Bulcock family. The generous layout with wide verandahs and spacious rooms shows how important hospitality and social events were to those who lived there.

The house sits on a large, elevated lot in Rosewood and can be viewed from the street, though on-site information signage is limited. Access to the interior is not typically open, so visitors should plan to appreciate the exterior architecture, verandah, and garden design from outside.

The octagonal room was a summer sleeping room 12 feet (3.7 m) across, with windows on all sides, built onto the north side of the house. A c. 1919 photograph also shows a winged front stair turning out into a flower garden adorned with statuary. Bulcock's firm, Bulcock Brothers' The Trade Palace, was a general store, not a hardware business.
