We are a licensed, insured, professional Architectural firm. Our corporate motto is, 'Prompt, Affordable, Professional'. Good design is not a luxury for the few, but an essential part of a quality-assurance process that can reduce construction and operational costs over the life of the building.

Services
Originally conceived in 1998 as affordable backyard suites for the City of Toronto, the Barrie BHomes is an executed version that will meet or exceed Passive House and Net Zero Carbon standards, while providing an affordable, modular solution that can be site-assembled with the least time and materials possible.
Use this calculator to determine your construction budget based on size, build quality and performance target, and we can help you determine the appropriate level of professional services and fees required to get the job done. Calculate a construction budget based on a) size, b) build quality, c) performance target.
Use this calculator to determine a high level overview of impacts of building types on embodied carbon calculations, as compared with operational carbon and costs. Calculate a carbon budget based on a) size, b) build type, c) building stories and d) performance target. Calculate a Carbon Budget relative to the project size, quality and performance target based on a 30yr.
We have made this handy calculator that lets you determine the energy performance of your home or building in the units of the most widely used Building Energy energy metric, the TEUI or Total Energy Use Intensity. The units are the amount of all energy sources in Kilowatt Hours (ekWh - where e stands for equivalent) required as a function of building area in square metres per year: kWh/m2/yr.
We asked, what if we scaled our building scale calculator up to the scale of cities where we could process millions of square feet and determine a cost savings over 30 years to justify the investment? The results are below. For a building that meets the Toronto Green Standard Tier 4, WSP has estimated a 3.5% capital cost premium over OBC minimum.

Andy Thomson is an incredibly gifted architect. My husband and I built our energy efficient home outside of Collingwood and were so pleased by his talent, professionalism and his attention to detail. Thank you. Three years later, the design of the home brings so much attention to many and it brings us so much happiness.
