Next to St Paul’s Cathedral in Melbourne’s CBD is a Gothic Revival building completed in 1892 by Reed, Smart and Tappin for the Metropolitan Gas Company, which it occupied until 1967. Following a detailed investigation of the fabric, the building underwent exterior conservation works in 2016 guided by Lovell Chen’s conservation team.
The focus of the works was the visible elevations, facing south and west, originally constructed in polychrome brickwork with exposed Waurn Ponds limestone dressings, both rendered circa the late 1930s. Patch repairs were also undertaken to the green slate main roof and the membrane roofs of the 1930s concrete additions on the north side of the building.
The key issue addressed was the deterioration of the limestone below the later render. A very hard material with a yellow set coat had been used, and we were asked to advise on whether this render could be removed. We advised that it was likely that the brickwork had been damaged by preparatory scabbling, which proved to be the case. A washcoat was used instead to even out the colouring, as earlier (sound) repairs had faded at a different rate than other parts of the facades.
The works included general render repairs and re-coating, and limestone consolidation.
