What can an architect's website tell me?

All 24 firms here give a web address. Look for photographs of finished buildings rather than renderings, and for work of your type and scale. A firm that designs schools and a firm that designs laneway houses are answering different questions, and the portfolio usually says which one you are looking at.

“His knowledge and expertise resulted in a smooth transition from design to build and I'm well on my way to owning my custom dream home!”
120 Terence Matthews Crescent B1, Ottawa, ON K2M 0J1
Featured

Our Pembroke team is moving in the spring — right across Pembroke Street East from our current office. The heritage building will be restored and updated while respecting the historical features that make it unique. New windows and doors with black contemporary frames, and black canopies, will give the building a modern flair. The new paint treatment will refresh the exterior. At the back of the building, one of the doors will be replaced with a window to make the interior layout more functional. The beautifully-painted mural on the side of the building will, of course, be left untouched. The interior is undergoing a transformation as well, but you’ll have to come and visit us in the spring to see our new office space!
