Comprised of remnant stone and redesigned into something of immense beauty that can last decades, with no maintenance, no chemicals and very little embodied energy. Coldspring Granite teamed up with McLennan Design’s Jason F. McLennan to conceive and launch this product line.


Small pieces of remnant stone from other stone products that are normally ground up as aggregate or left in piles are now utilized fully within Earth Measure. The product is part of the DECLARE Products protocol for unparalleled product transparency.

SIREWALL is an in-situ, high-performance insulated structural system that resembles and greatly out-performs sedimentary sandstone. Local aggregates, carefully selected for physical properties and color are combined with a small proportion of Portland cement and steel reinforcement, creating a monolithic wall appearance and final finish for exterior and interior surfaces.

This durable, healthy and environmentally benign building system can be engineered for use in high seismic zones and may weather directly exposed to the elements. McLennan Design is co-owner of Sirewall USA and is actively involved in its research, development partnerships and education. It is currently being used inHeron Hall.
