How much does a Passive House timber home cost compared to standard?

A Passive House timber home typically costs 10–20% more than a standard building regulation-compliant timber home. The premium covers: thicker insulation (€3,000–€8,000), higher-performance windows (€5,000–€15,000), MVHR system (€5,000–€10,000), enhanced airtightness detailing (€2,000–€5,000), and certification fees (€3,000–€5,000).

However, operational energy savings of 75–90% mean the additional investment typically pays back within 8–15 years through reduced heating bills.
