They have been building well over 2 years...they have been building since the 80's i think....visit the website at www.classiccenturyhomes.com
and yes...post tension slabs..here is what HGTV said about them... in short:
Today the building industry is taking the next step in concrete technologies by using post-tension cables in slab construction. Post-tensioning is a method of strengthening concrete using high-strength steel strands or cables, typically referred to as tendons. Slabs using the post-tension method can be built thinner, which can cut down on construction costs and curing time.
By employing post-tension concrete construction methods, home builders can deliver a superior product at reduced costs.

They listed it as a 'best practice' in home building..
Classic Century takes individual samples of the soil on each lot to determine the consistancy of the ground...and know how to cure the slab correctly.
