Lots of people ask how much it costs to build a house with 2x6 walls rather than 2x4. Sometimes they ask if 2x6 wall construction is really better than 2x4. Let's dive into the answers to both questions.
Of course, the bigger the house, the more wall studs you need, so it will cost more to frame a bigger house with 2x6 walls than a smaller one. I'll give an example of an average-size house so you can get an idea.
I'm currently building a 2,354 square foot home with a 2-car garage (488 square feet). That's 2,842 square feet of framing. The wall height is 9 feet, so 9 foot studs.
We have the top plate and bottom plate, which refer to the 2x4 (or 2x6) boards that make up the top and bottom of the walls, connecting the studs together. At the top, there are 2 boards, and at the bottom there is one. The one on the bottom, at least for the 1st floor of a house, is treated to resist moisture.
So far, we've added up the cost of the lumber so we know that going from 2x4 to 2x6 walls costs an extra $1,700.21 in lumber. We also need to take insulation into account.
If we use fiberglass batt insulation, we can get an R-13 batt (R-value refers to the insulation's resistance to heat flow, the higher number the better) into the 2x4 wall, and an R-19 batt into the 2x6 wall. In this house, there is 3,027 square feet of insulation.
There are 2 other minor items to consider: door jambs and thresholds for the outside doors, since they'll be fit into 2x6 walls, and the window sills, which will be 2 inches deeper. That's going to cost about another $100.
If we add all that up, the total is $1,951. 56.
So, when deciding whether it's worth it, you'll have to consider 3 things:

The current home on our property has been in existence for over 80 years. We love our property, and made our decision to build our new house there. Turner and Son was the first company we considered and we didn't have to look any further.
