Now, with a concrete slab design, you enjoy no room for pipes unless you already have the spaces inlaid. Of course, you could other saw or drill into the slab. A crawspace lets you append as you need to and is much more flexible beside mistakes, although it may offer poor support for calorific things above it and last a shorter time than a conventional slab. An entire vault is the best of both worlds if you can afford it. Is there anything else I should really consider?
Answers:    I've owned houses that enjoy been configured adjectives three ways and these are my thoughts. In CA, there are few basements due to underground cave in potential beside earthquakes and liquefaction soils. Crawl spaces are a unadulterated pain if you obligation to have work done on your plumbing or electric because near is such small space to work in. Often crawl spaces do not hold poured flooring (especially in elder houses) which is problematic due to insects and moisture. Slabs are also problematic especially if plumbing was installed through the slab. They are also prone to cracking within earth movement, next to invasive tree and bush roots and if not properly installed, next to moisture. Basements are great but difficult to insulate and heat. They also regularly have moisture problems especially when concrete or slump block is used contained by the construction or when there is coarse drainage along the walls.
What kind of climate are you surrounded by? Having the house up off the ground is better to avoid bugs approaching termites, and helps avoid flood destroy. But cold air can obtain in underneath. I bought a house not long that was built surrounded by 1927. It had a crawlspace, which be fortunate because we had to rewire it.
