Passive House CT Custom Interiors is a PHIUS-certified passive house builder and offers residential and commercial new construction and deep thermal envelope retrofit remodeling services for existing, traditionally constructed buildings. We have a team of advanced carpenters, finishers, insulators, roofers, siders, electricians, plumbers, and all electricity-based mechanical contractors for almost any sized project. We believe our builds should meet or exceed all known wall assembly and code changes coming so our clients stay current throughout the climate change electrical revolution using construction practices that, if done well, reduce the need and costs for a total second gut renovation.
