The origin of the building is not known with certainty, but its current custodians claim that it was built in about 1474 as lodgings for a chantry priest based at neighbouring Holy Trinity Priory.

[3][4] In about 1790, the building was converted back to a house, leased by Roger Glover and John Furnish, who ran a stagecoach business.

The feoffees retained ownership of the building, and they decided that it should become a parish room for Holy Trinity Church.

[1][3][4] In 1905, local antiquarian Walter Harvey Brook made major alterations to the building, adding a new staircase, bay window and fireplace, and creating a new door to the garden.

[1][3][4] By the 1980s, the building was in danger of collapse, in part due to vibrations caused by traffic passing along Trinity Lane.

In order to save it, the brick top storey was removed, and a new roof was constructed for the wing to match that over the hall.
