One of my favourite ways to unwind after a long day is curling up on the couch with a snack, a drink, and an episode of Architectural Digest on YouTube. There’s just something about critiquing celebrity homes—“Oof, that chandelier is trying too hard” or “Yep, I’d live there in a heartbeat.”
I recently rewatched Jennifer Garner’s episode, and she mentioned how her architect completely nailed her vision from just one conversation. No back-and-forth, no second-guessing—just a perfect watercolour sketch that became her dream home.
And that got me thinking: a great architect doesn’t just design; they get you. If you’re planning to build or renovate, choosing the right one can mean the difference between a dream home and a design nightmare. To help, we’ve reviewed the best architects in Ottawa!

Business hours: Monday to Friday: 8 AM – 4 PM
J.L. Richards & Associates Limited has been a trusted name in Ottawa’s architectural and engineering industry for over 30 years.
They’re not just another firm—they’re employee-owned, which means their team is personally invested in delivering high-quality work. This kind of dedication shows in their strong client retention rate, with 80% of their business coming from repeat customers.
Whether it’s a large-scale infrastructure project or a more localized design, they bring together experts in architecture, engineering, and planning to get it done right.
What’s also impressive is their global reach—this isn’t a firm that just sticks to Canada. They’ve successfully completed projects in over 75 countries, adapting to different environments, regulations, and sustainability practices along the way.
They also focus on environmental responsibility, Indigenous partnerships, and inclusive design, which says a lot about their values.

2. Kariouk Architects

Address: 179 George St #1204
Phone: +1 613-562-2211
Business hours: Monday to Friday: 9 AM – 5 PM
If you want an architect who’s fully invested in every step of your project, Kariouk Architects is a great choice. They don’t just hand over blueprints and call it a day—they guide you from land purchase to final finishes, making the entire process way more manageable.
A standout feature is their design process: instead of just showing you a couple of sketches, they create both physical and digital models of your future home.
And these aren’t just for show—you can open them up like a dollhouse to get a feel for the space. It’s an interactive approach that makes sure you’re involved in shaping your dream home.
Beyond design, they also navigate the nitty-gritty of zoning approvals and building permits, which is a lifesaver if you’re unfamiliar with city regulations.
One thing to keep in mind—they’re only available on weekdays. Still, if you’re after a firm that blends creativity with practicality while keeping you involved every step of the way, Kariouk is a great option.
A delightful experience
“Working with Paul and his team is always a delightful experience. Creative ideas abound to give us results that consistently exceed our expectations. We especially appreciate his enthusiasm when taking on a project and his commitment to deliver quality, both of which contribute significantly to client satisfaction.”
-Rosalie McConnell, Google Review
Very creative and patient
“So very creative and patient: Paul and his team were very kind and patient with us as we struggled to figure out exactly what we wanted. They developed many options with enough detail that even I could imagine what they were proposing. They were always professional and listened carefully. The timing could not have been worse–the stock market crashed so we did not proceed with the project. They were completely understanding.”

3. CSV Architects

Address: 190 O’Connor St #100
Phone: +1 613-564-8118
Business hours: Monday to Friday: 9 AM – 5 PM
We like how CSV Architects deeply cares about both sustainability and accessibility. They’re not just ticking boxes—they design buildings that cut energy use (think Passive House and Net Zero standards) while weaving in natural elements like greenery and sunlight.
If you’re tackling a big project—a school, office complex, or multi-unit housing—their eco-friendly approach is a breath of fresh air.
But here’s what really impressed us: their commitment to universal design. They go beyond ramps and elevators, crafting spaces that feel intuitive for everyone.
Need a washroom that works for wheelchair users and low-vision visitors? They’ve got it covered. Their team stays sharp on the latest accessibility rules, too, which means your project won’t just meet today’s standards—it’ll be ready for tomorrow’s.
One caveat? They’re geared for larger projects. If you’re renovating a cozy bungalow or building a single-family home, their expertise might feel like overkill (and their pricing might sting).
Nonetheless, CSV Architects is an excellent choice for those seeking forward-thinking and environmentally responsible spaces.
Great service
“I contacted Peter about a small commercial project I had planned. He was very helpful and was available over email and over the phone (something that I valued highly when searching for the right architects). Peter’s quote was very detailed, and every step explained, with the people responsible for each step. Great service.”
-Nicholas Rozman, Google Review
Brilliant designs
“We at McDonald Brothers Construction have had the privilege of working closely with CSV Architects over the last couple of years. Their designs are always brilliant and are always on the cutting edge of the newest green building initiatives. They are organized and capable of delivering complex building designs from demanding owners. They are a great architecture firm to work with.”

4. John Donkin Architect

Address: 138 Hopewell Ave
Phone: +1 613-730-6918
Business hours: Monday to FRiday: 9 AM – 5 PM
What we love about John Donkin Architect is how they blend real-world know-how with creativity. With 25+ years in architecture—plus hands-on construction experience—they get how designs translate into actual buildings. No ivory tower ideas here.
If you want a home or renovation that feels uniquely yours, they’re a great match. They don’t force a “signature style” on clients—they actually sit down, listen to your vision, and shape your ideas into something even better.
Another highlight is their design counselling service. Ever feel unsure whether you need a full architect? Maybe you’re just sketching out a renovation or eyeing a fixer-upper—they’ll give you expert advice without locking you into a big contract.
That said, they’re a small team—just two architects. While this means you get personalized attention, it could mean tighter availability for complex or sprawling projects.
Despite that, if you value craftsmanship over corporate speed and someone who’ll geek out over details with you, then John Donkin Architect is a reliable partner.
Brilliant results
“John found a thoughtful way to add a three-piece ensuite bath to a Westboro storey and a half house while remaining within the existing building envelope. I didn’t need more space; I needed the space I had to be better organized. The result is brilliant – a jewel of an ensuite bath, excellent closet space, and improved energy efficiency. I truly enjoyed working with John and the team from an architectural standpoint and with an outstanding contractor, Tom Vtipil of Otto and Sons Construction. Fabulous.”
-Stephen Murray, Houzz Review
Provides individual and focused attention
“My wife and I interviewed several architects. What we found interesting about John was his unique approach. We knew we would get his full attention and that was exactly what he delivered. Building an infill is tricky. Maximizing natural light and interesting sight lines was a challenge that John was up for. In the end our home is something that we were thrilled with. With time the small but important design details constantly remind us of how special and talented John is. John Donkin has a unique portfolio and provides individual and focused attention to each project.”

5. Simmonds Architecture

Address: 340 Catherine St
Phone: +1 613-567-7888
Business hours: Monday to Friday: 9 AM – 4 PM
Simmonds Architecture shines by mixing a sleek, modern style with a strong focus on being eco-friendly. They’re not just putting up walls; they’re creating cozy living spaces that are energy-efficient and good for the planet, using top-notch materials all the way.
Their green home designs have even earned awards, showing off their knack for integrating renewable energy systems and low-VOC materials into every project.
It’s also neat that they don’t stop at the architecture; they also offer interior and landscape design services to ensure every detail works in harmony. They even take care of the whole permit and regulatory process, which can be a lifesaver if that’s not your thing.
Just a heads-up, though—their focus on premium, sustainable materials can bump up the costs. So, if you’re working on a tight budget, it’s worth chatting about more affordable options right off the bat.
Overall, if you’re looking for an eco-friendly home with style, Simmonds Architecture is worth a look.

-Jen Pinkstone, Google Review
Balanced nature and lifestyle
“Christopher’s work is truly inspired. He balanced the rhythm of nature with the needs of our lifestyle. For us he not only created the most beautiful house we could imagine, but also a space we can call home.”
