Over 40 years of stone fabrication experience

Four decades in this trade changes what you notice. You stop seeing a slab as a surface and start seeing grain, direction and the place a vein wants to land. You learn which stone will look better in ten years than it does on installation day, and which will not. Most of that knowledge is invisible in the finished kitchen, which is rather the point. Led by Pina Petisi, our shop and slab yard on Beatrice Street is open to clients, designers and builders by appointment.

The slab decides.

Layout starts at the stone. Veining is planned across every cut before the saw touches it.

Cut once, cut right.

Digital templating and shop dry-fits mean seams land where we planned them, not where we hoped.

Built to age well.

We steer you toward stone that looks better in ten years, and away from stone that won't.
