Stephen Barnecut Architect AAA

Director and Cofounder

Stephen is a graduate of the University of Calgary’s Masters of Architecture Program. This program extended his knowledge of traditional architecture and taught him the fundamentals of modern architecture. It involved training in classroom and studio settings, as well as coursework in Edmonton and Barcelona, Spain. Upon graduation in 1999, he was keen to make his mark in the Calgary residential market and joined forces with a pair of like-minded partners to form Alloy Homes Inc.

Stephen’s tenure at Jager and AlanRidge Homes began in 2003 when he became Design Manager for Jager Homes. Within two months he was given the task of managing product development and design production for AlanRidge Homes as well. Stephen’s knowledge of AutoCAD allowed him to rebuild the companies’ standard models so that they were much more efficient to work with.

Looking for a tool to reduce design errors and improve efficiency, Stephen discovered AutoDesk Revit. Deciding that this was going to be a great platform to base a new design business on, in the spring of 2006 Stephen left Jager and AlanRidge to co-found Inertia Corporation.  Stephen has since been a strong proponent of Revit and has helped implement it at a number of firms.

Since 2008, Stephen has been a member of the Canadian Home Builder’s Association - Calgary Region’s Inner City Builder’s Committee, which has focused on design and construction issues specific to Calgary’s inner city development. Stephen was also an industry stakeholder in the rewrite of the Calgary Land Use Bylaw in 2007, and later a member of the City of Calgary’s Land Use Bylaw Sustainment Team Advisory Committee. In this role, Stephen helped City staff understand how City policy impacts design and development, as well as helped craft revisions to improve the Land Use Bylaw. Stephen was an influential proponent of attached housing which reached fruition in the creation of the R-CG district in 2015 that allowed for rowhouses in Calgary’s inner city.

From 2010 to 2014, Stephen Barnecut assisted Jayman in the role of Director, Product Development. In addition to his role as an Architect, Stephen is now responsible for Inertia’s business development, administration and human resources.

Stephen co-founded Gravity Architecture in 2014.


Paul Shannon

Senior Project Manager and Cofounder

As Senior Project Manager, Paul runs Inertia and Gravity's larger and more complex projects. Paul is an exceptional designer, technologist, and problem solver.

Paul completed the Architectural Technology program in conjunction with the Co-operative Education Program at Fanshawe College in Ontario in 1999. The Co-operative Education included one semester per year of on-site work experience, which put his theory into practice. Upon graduation, Paul moved to Calgary and soon began at Calbridge Fine Homes as their sole designer/draftsman and product developer, working on mostly custom homes and small multi-family projects. In the Fall of 2003, Paul moved to Jager and AlanRidge Homes as the Senior AlanRidge Designer and member of the product development team. At Jager and AlanRidge, Paul worked one-on-one with clients and was able to further hone his skills in the custom and estate home market. In the Spring of 2006, Paul left Jager and AlanRidge to co-found Inertia Corporation where he managed his own group of clients.

In 2009 Paul took a hiatus from Inertia to work at Robert Pashuk Architecture and pursue the RAIC Syllabus program. After spending a year and a half back at Inertia, Paul then took a role as Senior Architectural Technologist at Casola Koppe Architecture where he continued to work on larger multi-residential projects. He returned to Inertia and Gravity at the beginning of 2018 in the role of Senior Project Manager.

Kicking off her career working for Evans 2 Design Group doing architectural controls, Kat moved on to work with Jackson Baker McCormick Design Group. There she managed her projects in all aspects including the creation of detailed construction drawings, product research, permits, and working with each trades to ensure the end result met or exceeded expectations. As a member of the innovative product development team at Albi Homes she honed in on her love for design, and her team was rewarded with multiple Regional and National SAM awards. Bringing both her technical skills and her passion for design, Kat joined Inertia and Gravity in the fall of 2017 and is a welcome addition to our team.

Kat’s curiosity for how things are made and her enthusiasm to create extend well beyond her role at Inertia and Gravity.
