Drafting & 3D scanning for architectural stone

Stonemasons still exist and we should be proud to preserve our unique Canadian heritage — and even design boldly as if we still built cathedrals

An anchient architect at heart

After a carreer in graphic design I went to trade school to become a stonemason. I worked in restoration because I love natural stone and the monuments and temples from history. I follow the Archtecture Uprising movement which encourages the use of natural stone and tries to prevent big, ugly concrete boxes.

Old and new, it's all good

I measure and design projects using both traditional techniques and modern 3D scanning. I participate in the Canadian Stone Carving Festival, using manual tools, but also like making CAD drawings for CNC machines.


I am Justin Stahlman, a draftsman & stonemason in Montreal. Here I am at the Forges de Montréal during a collaboration between stonemasons and blacksmiths.
