Diagnosis first, budget second
For the question how much does it cost to refurbish a home, the answer depends on current building condition and intervention depth.
Without an early diagnosis, any figure is provisional and can fall short once works start.
Cost packages that define real budget
The highest-impact packages are usually structure, systems, thermal envelope, and regulatory adaptation.
Final finishes matter, but they are rarely the main source of major overruns.
Strategy to invest better
Prioritizing safety, habitability, and efficiency before aesthetic upgrades reduces risk and improves long-term value.
At BAU, we apply this methodology for residential refurbishment in Mallorca.
