Edwardian, Victorian and interwar homes each fail in their own predictable ways. Knowing which helps you budget.
After enough period renovations you stop being surprised. Each era of Melbourne housing has its own characteristic problems, and knowing them lets us tell you at quote stage what the likely variations are rather than discovering them together at week three.
In Victorian terraces, the constraint is almost always the party wall. You cannot chase it for waste, so a new upstairs bathroom needs an internal stack, usually inside a bulkhead the builder frames. Upstairs floor depth is also tight, so the fall on the shower waste has to be planned rather than assumed.
In Edwardian homes, the recurring issue is kitchen and laundry waste. These were added later, often with almost no fall, and laundries teed into bathroom lines in a way that would not pass today. If you are extending at the rear, this is the moment to fix it properly.
In interwar bungalows, look under the old shower. Renovations from the 1980s were frequently laid straight over the original floorboards without addressing fall, and years of water into the subfloor means joist repair before anything else can happen.
In 1930s apartment blocks, the cast iron stack is the thing. Original stacks are now well past their life and are usually common property, which means the owners corporation is responsible — a distinction that has saved our clients real money more than once.
None of this means a period renovation is a bad idea. It means the contingency in your budget should be a real number, and your plumber should be able to tell you specifically what they expect to find in your particular house.
