At Transformer Homes, we’re based right here in Thomastown, and we’ve spent years building and renovating homes across Melbourne’s northern suburbs.

Who is the site supervisor on my job, and how regularly will they be on site? How do you manage waterproofing inspections and sign-off from the VBA? What happens if a trade runs late and causes a delay to the overall schedule? 2.
