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. We serve the private residential and commercial sector, from small alterations and additions to restaurants, breweries and airports. Having learned the craft of architecture from some of the best firms in North America and Germany, we integrate structural and mechanical design and preliminary cost estimating from day one. With a focus on deep sustainability, Thomson Architecture projects strive for zero-carbon, net-zero energy, and Passive House levels of performance wherever possible. In order to meet these high performance targets, we are unique in Canada for our innovative approach to reduced building material and labour-saving detailing, resulting in exceptional construction cost savings. Click below to see more;

Ecometrics & Thermal Analysis

Heat-loss isn't just a waste of energy and money, it can also deposit unwanted humidity in your building's wall, floor and roof assemblies, resulting in premature failure, mold and avoidable damage.

We provide thermal imaging of your building inside and out to help determine the potential cause of condensation, rot and leakage. We can also undertake a review of your utility bills and establish a Total Energy Use Intensity (TEUI) rating based on your building's area, and compare this against a National Average for the age and type of your property. Our review includes a comprehensive report and suggestions for improvements and renovations for improved energy performance and reduced carbon footprint. We can also help you establish a pathway to make your building carbon-neutral, net-zero energy or both.

Indoor Air Quality

Indoor Air Quality is routinely up to 5x worse than outdoor air. This can impact our health, worsen symptoms of asthma, impair cognitive function and affect the quality of your sleep. But how would you know? We offer a 30-day, comprehensive, multi-zone IAQ study that includes:

Temperature Distribution (ie. upstairs/downstairs) | Humidity | Pressure | Radon | CO2 | Oxygen | TVOC

We provide interval sampling up to 5 minutes on most of these measures, and provide you with a comprehensive report at the completion of the review that will help you to determine whether it may be prudent to undertake cleaning, balancing & maintenance of your systems, provide additional air filtration equipment and or Heat Recovery Ventilation. As we are not a reseller of these additional services or equipment, you can expect an unbiased opinion from us on your IAQ.

Community & Resorts

We have experience in community living and design, from ad-hoc student villages in Germany, to co-housing in Toronto and even developing an eco-village in Quebec. The growing trend of co-buying, co-habitation, and basically all forms of community organization and living bring opportunities to design for both social and spatial structures. Finding a balance between private needs and public amenities can be best discovered in a public design forum, with architect as mediator. Andy has led several teams in consensus-building exercises aka. ‘charettes’: multi-stakeholder design workshops where all input is considered, filtered and synthesized, resulting in a multi-dimensional functional plan where everyone feels heard and included. Contact us to learn more!

Renovations & Additions

We help our clients to evaluate multiple properties, as well as review and inspect existing buildings. We create laser measured, 3D plans existing buildings. We also help to develop budgets and building cost estimates and complete design and construction administration services. From basement renovations to multi-storey additions, our software is specially designed to create drawings for existing, demolition and proposed conditions, facilitating your permit application drawings.

Advanced Geometry

Specialized in geodesic, platonic, polyhedral and otherwise rational, efficient and other geometries that may require advanced coding, parametrics, custom scripting and research and design to construct digitally and test at full scale. Inspired by the always metaphysical R. Buckminster Fuller, our exploration of ephemeral design principles, prefabricated housing, load-balancing structures, the meta-mathematical geometry of nature as understood by Bucky is a constant theme in our projects.

            Bucky’s Ghost

            Bucky’s Ghost

            Geometer, Cosmologist

            R. Buckminster Fuller’s presence in our office is palpable. Since ideas are beyond time, in his own way, Bucky continues to exercise influence here and now. Our project portfolio is a continuation of Bucky's ephemeral design principles, from our prefabricated housing solutions to our 'flattened tensegrity' large span timber structures that embody precession and load distribution. The meta-mathematical geometry of nature as comprehended by Bucky is a faithful and constant companion in all of our projects.


            • As an industrial designer and construction professional, I highly recommend Thomson Architecture. They are professional, enthusiastic, and a pleasure to work with. We could not be happier with our home.

              Robert & Maria Iantorno
            • Like all other architectural visionaries of modern times, Mr. Thomson foresees not merely a radical building type, but also a new kind of human being to fit the built prototype. It may well be that the long-suffering environment will eventually turn on us in some catastrophic fashion — if global warming is not already such a calamity — forcing our conversion from wasteful people into more mindful folk. Should this apocalypse come upon us — or, better still, well before it actually happens — we should be listening to what designers such as Andy Thomson are telling us, and to what they have learned.

              John Bentley Mays, The Globe and Mail
            • Let me introduce you to Andy Thomson. He is a rock star. Andy works for two firms in Canada as well as his own. Since he does not sleep, he also has recently providing some assistance to our new reseller in Canada (Ardent). Andy’s passion is about design and how to implement ArchiCAD in large firms/large projects. To this end, he has put up a site to help the community to implement ArchiCAD on large projects. He is a terrific speaker with lots of big projects completed and I think he will be an excellent keynote speaker for the Nottingham (Archicad University 2007) Event.

              Dominic Gallello, Former CEO OF Graphisoft, Autodesk
            • As a fellow architect, Andy has been a valuable resource to our community in assisting with tools and expert advice over the years. His demeanor, patience and willingness to help should weigh heavily in your decision when seeking a building design professional.

              Forest King, Architect
            • Andy Thomson is one of the very few architects I would consider for doing anything green and modern.

              Anyone can put up a wall of glass and say they’re creating a beautiful living space by bringing the outside in. Anyone can slap on some solar panels, add fly ash to the concrete, and claim a house is green. The world abounds with such designs, but only a true professional can combine all the parts into an integrated whole... To be able to combine this with clean lines, a surprisingly spacious feel, and just enough funkiness to add character, is rare.

              I’d definitely recommend Andy for any low-impact modern design project.

              MIke Crawford, Maine Residence
            • I started working on a “fully sustainable family compound” design (for the Napa Valley) with Andy Thomson in the Fall of 2009. It was truly the most fun and productive collaborative project I have ever participated in. Each suggestion brought up an even better new idea and Andy’s extensive knowledge of “cutting edge”, “state of the art” architectural projects, innovations, methods, environmental standards and software made for an easy, exciting and productive adventure. Andy has a way of making an architectural design project a true collaboration, instead of just an idea forced upon his clients. We have as yet not fully finished our design, but the process has been fruitful and exciting. Andy is an architect with integrity, imagination, wisdom and courage. That is a total winning combination for any project!

              Christine Remy, San Francisco, CA
            • I first met Andy during architecture school. He really stood out and brought years of experience to the studio, which we all learned from. His experience in Germany, I think was invaluable as they are the culture that cares the most about quality, timeless buildings and they are at the forefront of sustainability. He applies this experience and knowledge to his Canadian projects. Andy truly practices what he preaches and has a ton of experience living a sustainable lifestyle. I rely on Andy whenever I have a question about architecture, details, or if I just want to toss around ideas. He’s the best. He’s literally an encyclopedia and his energy and excitement for what he does is infectious. Andy is hungry for knowledge and is constantly seeking out best practices and innovation. His mastery of technology and cad programs also ensures that he works efficiently. I strongly recommend Andy for any scale of project and clients are lucky to have access to his creative and rigorous approach.

              Julie B, Architect & Planner
            • Andy Thomson is a forward thinking innovator in building design. His work causes you to expand your notion of sustainable living, while simultaneously still ‘thinking inside the box’. Andy is an indispensable resource as an architect for anyone wishing to consider their environmental impact in new builds in our Canadian climate.

              Violet Shearer, Toronto, Ontario
            • Andy is intense and passionate about going low-impact with a strong sense of design. He has lived his own creed, experimenting with his own dwellings, and knows what he’s talking about on an experiential level. Yet Andy is also adept at listening to his clients and finding ways to implement their goals, even if they don’t share all his passions. That’s a combination we’ve appreciated while working with Andy on a number of designs.
