Astrea is a heritage-listed duplex (building) at 19 Bank Street, West End, Queensland, Australia.

The architect may have been John Ibler, who in February 1888 called tenders for a pair of semi-detached brick and wood residences in Bank Street.

These included his son Magnus Jensen, a solicitor and Member of the Queensland Legislative Council 1904–15, who is first listed in the post office directories as resident on the east side of Bank Street in 1888.

In 1909 the building was sold to Thomas and Harriet Walters, who converted it into a single residence, and possibly gave it the name Astrea.

[1] The separate identity of each house is highlighted by a small gable at either end of the top verandah, each with an intricate fretwork pediment.

Astrea has considerable aesthetic appeal, and contributes significantly to the historic West End townscape.
