hi all…..i’m planning a 1400′ one floor house for my family, & need to know the pros & cons of slab-on grade vs. a full foundation and frame floor. i’d like hydronic heat in the floor, & wood and slate for floor finishes. i’m in the pacific northwest (no real frost line or freezing ground) , on land that has a clay layer within a few feet of the surface. any opinions are appreciated. thanks marko

IMHO I prefer raised floors with crawlspace and full foundation. Pros - If done properly, more resistant to water intrusion; less prone to insect entering the house through cracks in the slab-on-grade; all sewer/water lines can be routed and are exposed for future maintenance; future wiring/plumbing access if needed; floors are more comfortable (give a little).
Cons - More expensive; might be more prone to termite infestation; less stiff (for flooring); must keep vents intact or you'll get critters living under and in your home.
I agree completely as to ease of repair. Our slab house will be a royal pain to re-pipe.
Also consider where you want to be when you look out the window -- at ground level, or somewhere higher? Our raised foundation house gives us better separation from the public sidewalk outside, the slab house puts us down among the roses.

yes but with a slab on grade, if the plumbing is done right you would never have to replumb, because they no criiter under there tearing up yhe insulation and plumbing. Beside when you get old you can walk right in without climbing steps that hard on the knee. slab on grade a better handicap house

In some ways, true enough. But with good ramp design, the finished floor elevation is unimportant. A pier & beam gives a higher vantage point, this can be a concern if the users of the house 'stand' no taller than sitting in wheelchair. That extra foot of elevation provides much better views. Also, it is significantly easier to install porches, which not only provide shade, but also increase the accessable living space (in a way that a patio in the rain cannot).
There are pros and cons all the way around the argument.
The worst "con" argument is the transition from garage to house. The garage floor just about has to be slab on grade, now there's a foot or two to get in the house. Without some careful design, this can be a pain. This is where I prefer a detached garage that is connected by an enclosed breezeway. The breezeway lets you handle the elevation change, it also can act as a mud room type of space.
Oh well, off my soap box. Again.Occupational hazard of my occupation not being around (sorry Bubba)
