We had Lagois design and undertake an exterior renovation on our 1950s house. The entire process was very smooth starting with the designer quickly getting our style and coming up with an option that met our tastes. The work went very smoothly and the quality of work is very high. Some inevitable issues came up but they were on it right away with no additional costs. I wouldn’t hesitate to work with them again!

We had the pleasure of working with the Lagois team for a full house renovation including an addition in 2019.

We found the team extremely knowledgeable and professional throughout the process. They were able to bring their ideas to us as well as listen to what our hopes and dreams were for the project.  They were responsive to any and all questions that we had as we were going through the process – all of their contractors were personable and professional.  The job was completed to a very high-quality level and on time. We are very pleased that we chose Lagois for this work and would highly recommend them.


I’m SO thrilled with my new space! Working with Lagois on updating my 1977 riverfront home was a fantastic decision for so many reasons. Communication was great, design support and sourcing outstanding and Lagois’s building standards are high, making the end result a beautiful home that will make us happy for many years to come.

I loved working with the team, starting with Herb, Jeff and Sophie who worked on blueprints until we had it right and on budget.

Interior design professional Catherine Leibe was key to channelling the mid-century modern vibe and was so fun to work with.

Our site supervisor, Tom Felts, made the whole process as easy as possible for us (we lived in the basement during construction) and was a true quality control manager. He kept the finishing standards high and met us weekly to keep us up to date and provided notes on everything discussed.

The Lagois 5 year guarantee provides great peace of mind too.

I underestimated how life-changing a renovation can be. We are so incredibly happy with the home Lagois created for us.


We are so happy that we chose to work with Lagois.  We are loving our new addition, which nearly doubled the square footage of our century home in Westboro, adding more functional space for family as well as a tranquil master retreat.

The design process was a positive experience. Starting out, we knew that our old addition had to go, but we had only general ideas about what to put in its place. Chris and Jeff helped us refine our needs and priorities in keeping with our budget.

The resulting design effectively integrated the new with the old, both inside and outside, maintaining our home’s historic character. Given the age of the house, we were nervous to begin demolition and construction, so we really appreciated how Lagois works with tradespersons to identify precise costs before entering construction contracts.

We enjoyed working with Sophie to select all of the finishings and love the end result.

We could not have had a better site supervisor than Darren.  He paid close attention to construction details, communicated with us regularly, and did what he could to minimize disruptions to our lives.  Darren clearly set a high standard with the tradespersons concerning cleanliness and respect for our property. He also maintained good relations with our neighbours.  Living in a house during construction is not for everyone, but he helped us make it work.

We also appreciated how Lagois made it possible for us to collaborate easily, despite our hectic schedules, by transacting things by email or meetings at our home after hours.

We were happy that the project came very close to our original budget and completion date.  The quality of the work is evident.  Once we are ready to renovate more parts of our old house, Lagois will be our first call.

We had Lagois design and build an extension to the front of our house and detached garage. The project required some adjustments because of city requirements and Jeff the designer from Lagois was able to provide us options and keep us informed on the process as things came up. We are very happy with the end product and the way that Lagois worked with us and completed the project with quality and professionalism. We wouldn’t hesitate to rehire or recommend them.

During construction, Lagois treated our house with respect. Everyone acted like it was their own and we felt comfortable leaving the house in their hands. I came back several times during the reno and the house was always left clean, swept, and with no tools or equipment lying around. This attention to detail made me feel confident that we made the right choice when we chose Lagois. They were trustworthy, knew what they were doing, and always had a plan.

Tom was everything you want in a construction supervisor. I was working with another contractor to waterproof my basement and I hired them to replace a foundation wall. There would only be about 2 weeks when the two companies would have overlapping schedules. However, that didn’t work out. The foundation company had constant delays which resulted in Lagois not having access to the basement or backyard. Tom kept juggling the work schedule around every new delay.  Even with the extensive delays caused by the foundation contractor, Tom made back four weeks of lost time.

Lastly, the foundation company created damage to my house.  The new wall they built passed their engineer’s inspection, but Tom noticed a problem. He took charge and explained to them why it would fail.  I don’t know what would have happened to the house if Tom wasn’t here.

Lagois worked with us in designing a 600 square foot extension over our two-car garage and then in supervising the contracting and construction. It was carefully designed to match key features in our 2-story home, such as matching the semi-circular window in the entrance to the house. Thus it looks like the extension was always a part of our house. It may end up as an art studio in the future but is currently rented as an apartment. Thus it has a full bathroom and kitchen, the kitchen, dining room and bedroom sections laid out in an open concept. The unit incorporates in-floor heating powered by the unit’s water heater and thus solves the problem of being built over an unheated garage. There is also air conditioning and tenants are very comfortable. Tenants have their own private entrance via an outside staircase, hidden from the entrance to our house. Thus they are not bothered by us and we are not bothered by them. There is also an inside entrance to the unit from the second story of our house, which is blocked off until it becomes an art studio someday.

We chose Lagois after seeing their design work in an article in the Ottawa Citizen. We wanted an extension behind our house that would blend with the natural space, inside and out. We were not disappointed. Working through a process that started with a lot of listening and revising, the design was solidified so that layout, materials and finish were all up to or well past expectations. Despite the intrusion on the kitchen, the process was not overly disruptive to our home, owing to the respect shown by the Lagois team and the care taken of both their worksite and our home. Yes, there were delays introduced by supply chain issues of Covid-19, but we were always made aware of items as they occurred and offered choices. With attention to detail, they delivered from start to finish, and more. Not only is the work warranted for five years, Lagois come back yearly to ensure that all aspects of their work continue to please. So, yes, we would highly recommend Lagois. We wanted a top-notch job. What we received was a professionally built, expertly finished space that delivered on every aspect we were hoping for and more.

Last November and December, I had the crew from Lagois Design Build Renovate install a walk-in shower in my condo. In order to do this, they had to remove an existing tub and toilet. This required them to work within the confines of the condo rules and regulations with respect to noise, product removal, use of the elevators to mention just a few of the items they had to deal with over the three weeks or so that the job took to complete.

To say that Lagois accomplished all of this with a very high degree of professionalism would be an understatement. Many of the owners asked about them and the job they were doing.

The finished project was nothing short of amazing. I had help from their design team as well as those who did the actual construction. The team showed up on time and worked causing as little inconvenience to me as possible. Trades came when they promised, work was finished on time and my apartment was left spotless.

I was not only impressed with the design and finished product but also the time and care the team took to make sure the job was done safely. Equipment was neatly stored on-site if needed or removed at the end of the workday. A box containing the safety equipment was on-site at all times and any trades who entered were made aware of this. In short, every detail no matter how small was taken care of with a level of professionalism that certainly is not that common today based on what friends have told me about similar jobs with others doing the work.

Those who have seen the finished shower are certainly impressed and I know it has provided me and some guests visiting from out of town with very a valuable, attractive and practical addition to my condo I would not hesitate to recommend Lagois Design Build Renovate to all of my friends and have already been asked about the company by others in the condo.


Superb service and delivery from start to finish. They renovated our kitchen by first creating the design and serving as the general contractor for all the contractors they brought in. Some of the renovation work was done by their own staff. They also helped with shopping for all the products and details required. I absolutely love my new kitchen and I highly recommend Lagois to anyone considering hiring them.

Dave & Melissa

When we decided to renovate, we looked to Lagois because of their all-in-one process. We knew we wanted extensive design help, so it was important to have in-house designers supporting us. Lagois definitely delivered on that front — so well that we added finishing the basement to our project thanks to an excellent proposed floor plan! We also ended up with a unique kitchen we’d never have dreamt up ourselves. We love it all! We were also really pleased with the careful oversight provided during the build phase. The site supervisor always ensured that work was done to the highest quality, spotting things we wouldn’t have noticed. Add to that the five-year warranty and we knew we could be confident about the final result.

Gail & Andrew

Despite all the uncertainties and challenges related to Covid, the Lagois team was able to deliver our dream renovation. They listened to our ideas and objectives and made them a reality. It was a major renovation with a lot of moving parts to track, which was only made more challenging by Covid. Lagois was professional, paid attention to detail, did quality work, and was great to work with. We always really liked where we live but now we truly love where we live!
