Digital + Hand-Made Converge at Boston Valley Terra Cotta
Even for a small restoration job like 333 North Michigan Avenue, Boston Valley Terra Cotta’s commitment to quality never falters. In the same innovative process that drove the Alberta Legislature Dome restoration, the two blocks that require replacement are first drafted and the basic profile of the unit is milled on our 5-axis CNC router. Next, one of our skilled craftsmen, who has practiced for more than two decades, hand shapes the details out of plasticine.

The combination of digital production and hand-made detail is part of what makes Boston Valley so unique. The ability to combine state of the art technology with methods that have been used for centuries is truly rare.

A single detail is molded to match the original block.
And it is only at Boston Valley that one will find the same care and service go into all jobs, no matter the scale or scope.
