Bathrooms are the hardest rooms in a period house, and Middle Park is a suburb of period houses. Behind those Victorian and Edwardian facades, a bathroom renovation is rarely a tiling job: it is waterproofing inside old fabric, ventilation where there was never a window, services threaded through walls that pre-date plumbing, and light borrowed from wherever the plan can spare it. Get those right and the room outlives every trend; get them wrong and no stone bench can save it.
Bathroom renovations arrive at every price point, but the version worth doing in a period home, structure, waterproofing, ventilation and light solved together, usually sits inside a larger interiors scope. Across BY Projects' delivered work, interior projects of that kind have ranged from approximately $230,000–320,000. Portfolio examples, not a Middle Park price guide: the feasibility session prices your actual room, in your actual house, with the fee fixed before design starts.
Our Dudley Street project in West Melbourne rebuilt the interior of a 1990s apartment around bespoke joinery and a full thermal upgrade, delivered in 2024: wet areas, services and comfort engineered as one job. The same interior discipline ran our Alexander Street heritage kitchen in Box Hill, and the practice's wider Port Phillip record includes the Alfred Street and Lyon's Den projects nearby. Barbara taught building science at university level for around a decade, and that training is the difference between a bathroom that photographs well and one that never grows mould, and in hundred-year-old fabric that knowledge is not optional.
