Reference price vs real construction price
The query old house renovation price often starts with an average number, but real cost depends on confirmed technical scope.
Without structural, roof, and systems diagnosis, error margin is high.
Mistakes that increase cost
Most frequent mistakes are demolition without strategy, choosing finishes before system resolution, and starting works without a full execution project.
Each of these leads to rework and budget changes.
Method to define a useful budget
An itemized budget with defined scope and quality standards allows fair quote comparison and better on-site decision control.
At BAU, we apply this method in old-house renovations for stronger cost predictability.
