The new house has a spot for the RV 14 foot door so it should fit. they say we can close july 20th

Congratulations on the completion of construction! The size of your garage is imposing! Honestly, I don't think I've ever seen such parameters before. However, I would not refuse such a thing. I have been thinking about building my house for a long time. A friend advises me to contact a company that helps you design a house plan taking into account all the details https://www.boutiquehomeplans.com/. But it seems to me that I still need to consult with my wife. By the way, what materials do you use to insulate the walls? Many have recently been using special plates that keep the heat inside.
