The house was built in 1861 for Edward Barton Southerden, a successful Queen Street draper and later first Mayor of Sandgate, to a design by James Furnival who had recently established his practice in Brisbane.
Extensions have included an 1876 design by Richard Gailey.

In 1882 it was sold to Richard Edwards who gave the house its Welsh name.
Edwards was a partner in the drapery firm Edwards & Chapman, and a director of Telegraph newspapers for thirty years.
He became the first member for Oxley in the Australian House of Representatives in 1901 and retired in 1913.
In 1896 Edwards bought and demolished the neighbouring Athol Cottage and established Bryntirion's large garden in its place.
Richard Edwards died in the house on 29 October 1915.
The house remained in the family, occupied by his grandchildren and used as a doctor's surgery.
