The Bybee Stone Company procures Indiana limestone locally from quarries productive for more than a hundred years. Limestone, within the Oolitic deposit region, is as much a way of life and source of community pride as it is a building material.
The natural beauty of the limestone is revealed as skilled craftspeople—often longtime employees of the company and with multi-generational ties to the craft—shape it into pieces of our built environment that last for generations.
This durable character and aesthetic quality have been vital to the property value of stone buildings and their communities. As a contemporary green building tool, the physical properties of stone can provide a lasting and non-toxic material as well a temperature-stable environment.
As a building material, limestone has the qualities necessary for sustainable construction.
