Short answer
Building a Passive House typically costs 5–10% more upfront than a standard build, but delivers major lifetime savings in energy bills and maintenance.
Full answer
The cost of a Passive House depends on design complexity, size, materials and certification requirements. On average, expect 5–10% higher upfront construction costs compared to a conventional build. However, these costs are offset by significantly lower heating and cooling bills, reduced maintenance and improved property value. In many cases, homeowners recoup the additional investment within 5–10 years.
Why this matters
Budget is a key factor for most clients. Knowing the upfront and long-term costs helps make informed decisions about whether Passive House is the right approach for a project.
