 Outside Magnolia House, Regional General Contractor Alex Munson with Munson Construction says she's now a passive house enthusiast. I'm coming up on 18 years in business, and so I've built homes all the way from 200 square foot tiny homes all the way up to 4,000 square foot homes. I can build any plan, any design, but I do desire to stay in the passive house energy efficiency range and will definitely be using these practices in all my homes.
