I was once told by a contractor that the reason that contractors love open floor plans is that those types of home are cheaper to build.
And everyone I know who has bought one regrets it.
As a former builder I would say there is not much difference in the construction cost of “open” vs. traditional design. And in most cases, the cost to build increases in an open concept home.
There are many variables which tend to offset each other. Engineering costs? When you remove walls, the ceiling joists span greater lengths requiring the increase in material at load points and above the ceiling. Ceiling height? Vaulted or traditional? Open design tends to have more vaulted ceilings requiring an upgraded joist system. Open design also increases the square footage which also translates to more floor to finish. In the past number of years, that means more hardwood flooring as the preferred design choice.
Also, kitchens tend to be larger in open design, ergo, more tile. Cabinet space tends to actually increase as much of traditional cabinetry just moves to extended base cabinets and center islands. Oh, and more countertop space to cover.
Open design also requires a little more in the way of HVAC as it is more difficult to maintain temps in larger spaces. On the downside for the homeowner, it is a little more costly to heat and cool as well.
But as far as regretting open design? Maybe one man’s trash is another man’s treasure? And I can say I know plenty of friends who prefer an open concept. The fact that open concept homes have trended means a whole lot of people favor them. I’m reminded of the Yogi Berra line, “Aw, nobody goes there anymore, it’s too crowded.” :-)
As for me, I have lived in homes both open and traditional and much prefer open. Teenagers? Hah, my kids grew up in an open concept home and I had no problems with noise. When they hung out with their friends and watched movies or sports events, it was awesome. And I even sprang for the pizza delivery. When my daughter would practice playing her guitar, it was beautiful. Anyone can play the stereo, but when it is your child that is providing the music? Well, that’s just downright magical. With all that “noise”, the house was alive and it made my heart smile.
