Most houses we build carry stone somewhere, and the decision that changes the building is not which quarry it comes from. It is how the face is cut.

Machine-cut stone gives you flat, regular blocks with tight joints. Laid in even courses and left unrendered, it reads as a considered surface rather than a rustic one, and it suits a house with quiet lines and large openings. It is also the most forgiving to build with, because the blocks are consistent and the bricklayer is not fighting the material.

Hand-dressed stone is slower and looks it, in the good sense. The face carries tool marks, the colour varies block to block, and the wall gains a depth that a machine face cannot fake. Pair it with crisp white render on the adjoining elevations and each material makes the other look more deliberate. It costs more in labour, and the cost is visible in the result, which is the only kind of expense worth defending to a client.

Rock-faced stone is rougher again, with a split face that throws real shadow. It works best in bands and bases rather than whole elevations, and it is the one most often overused. A house faced entirely in rock-faced stone stops reading as architecture and starts reading as landscaping.

The other decision is where to stop. Stone to the ground floor and render above is a familiar move because it works: the heavier material sits where the building meets the earth, and the lighter one carries the upper storey. Reverse it and the house looks like it is about to fall over, even to someone who could not tell you why.
