Slab house or raised house: what moving the sink actually involves
A Meyerland ranch home on its original slab and a Meyerland home that has been raised behave very differently once the kitchen floor opens up. On the original slab, moving the sink or adding an island with water means cutting concrete, rerouting the drain to the nearest stack with the right fall, and patching the slab before flooring goes down. It is routine work, but it is loud and it sets the order of the schedule. On a raised home with a crawlspace or new elevated foundation, the same move happens from below. The plumber works under the floor, the drain can go almost anywhere, and the kitchen above stays intact until the finish work starts.
Gas follows the same logic. A range that moves from a wall to an island needs a new line, and on a slab that line is trenched alongside the drain. Under a raised floor it hangs from the joists. Electrical to an island is easier than most people expect on either foundation, but the code-required outlets on the island still need a conduit path. We map every fixture move on the plan before demolition so the plumber, electrician, and concrete crew all know what is coming. The City of Houston inspects the underground or under-floor work before it is covered, so those trades are scheduled early in the job.
