Natural stone cladding comes in four main formats. They can all be cut from the same stone — slate,
quartzite or sandstone — but they give completely different walls, and they ask very different things
of the person installing them.
Choose the format first, then the stone and colour. As a rule of thumb: the more the stone is prepared
before it reaches you, the faster and more predictable the installation; the less it is prepared, the
more the finished wall depends on your stonemason’s eye — and the more character it can have.
