Looking to build a 2000-2200 sqft pier and beam style home on a slab. Looking for recs on a builder in Houma/Thibodaux area and also any tips, what you wish you would have done different.

So a raised house on cinders but on a slab instead of bare ground.

Property is 7.5ft above sea level, in a flood zone AE so base elevation is 10 ft, not really a fan of a traditional slab house on a 3 ft mound of dirt, and I’ve been told if you go an extra foot above base elevation it drops your flood insurance premium drastically. There’s a handful of houses being built like this around this area.

Unless it has changed its a 25% per ft. reduction in insurance cost up to 3 ft. above flood stage. For a possible 75% savings.
This was info from three years back so may be different now.

Just curious, but how much extra does that cost to do versus building directly on the slab?

Seems like a waste of money pouring a slab beneath the house like that. Continuous grade beams beneath the piers would require less concrete. How do you prevent water from puddling beneath the house if there is a slab present? Drains? Hope they slope it correctly to the exterior?

Sounds like your answer is to stop by one of these being built and talk to them to find out who their GC is/owner is...

This is an expensive way to build a foundation.

A little extra info on building above the BFE. Elevations certificates are filled out with elevations to the nearest tenth of a foot. Fema rounds off these elevations to the nearest foot for insurance purposes. Also check elevation requirements with city and or parish if applicable. Their requirements can be higher than FEMAS.

If you build to a 10.6 you pay insurance based on a 11.0 elevation or what's called a +1. My point is if you plan on building to a 10.0 why not go up another 0.6' or 1.6' to get a reduced premium. Your insurance agent can do a what if on these elevations to see how much the premiums are reduced.

Make sure the same surveyor sets a mark for you to build by and fills out the elevation certificate. I also suggest letting the surveyor check the top of forms before pouring concrete just encase the contractor made a mistake. Its easy and cheap to raise forms if they are too low.

You need to completely encapsulate the crawl space.

Here is some good info on insulating your crawl space.

Check out your ABFE and BFE to make sure the numbers are the same. Sometimes one will be an inch to a foot off and you'll want to check with insurance companies in the area to see which one they prefer. It would suck to build at 3ft and you needed 3ft 1 inch.

So, for info on why builders are doing this:
The building code requires continuous concrete footing with rebar under the piers. Many builders find it easier and a better finish to form the slab with a 2x6 and cap the area with a finished slab. Some grade it to 2.5-3 inches and finish it out. It only costs about 2,000 dollars and you get better drainage and easier working underneath. Its also easier/more likely to finish level rather than doing just footings.
I also would advise to stay foam closed cell under the home. Moisture trapping is probably my biggest concern now with this style construction. The most popular flooring is water proof and doesn't breath at all. Your home being cold inside and hot outside, I have seen problems with condensation.
