Addison Design & Build

I'm thrilled with the job Addison Design & Build did on our renovation - the work was done on time, on budget, with everything clearly communicated. As with any renovation, unexpected delays and complications arose but there was always a sense of control and a clear way forward. Any issues were quickly dealt with to my satisfaction. The staff are professional, diligent, and polite. We love the new space and the quality of work is evident. If you are seeking clear communication, calm management, and quality results, we recommend considering Loren and team for your next project.

We hired Addison Design Build for a major renovation of our semi-detached home in The Junction, and the scope was anything but simple. The project involved underpinning, crawl space excavation, steel beam installation, and rebuilding portions of the foundation from under our home to create a functional crawl space. It was highly technical work, and Addison handled it with confidence, care, and professionalism from start to finish. One thing we really appreciated was how well they understand older homes and the importance of improving them properly. Rather than covering up issues, they took the time to address everything the right way. Floors were carefully leveled, structural challenges were resolved correctly, and real attention was paid to the details that matter in a century home, such as eliminating squeaky floors and ensuring long-term stability before finishes were installed. The house now feels solid and not creaky. The main floor was redesigned into a true open-concept layout while still respecting the heritage character of the home. The changes felt thoughtful and intentional, preserving the charm of the house while making it far more functional for modern living. The entire team and all trades involved were friendly, professional, and respectful throughout the project. It was clear that everyone worked well together and took pride in what they were building. The level of finishing throughout the home is exceptional. Just as importantly, Addison was very clear about expectations from the beginning and consistently delivered on them. Communication was strong, timelines were managed well, and there were no surprises at the end of the project. We could not be happier with the final result and are genuinely excited every day to live in our home. If you are renovating an older house and want a team you can truly trust to do things properly—from the structure all the way to the finishes—we cannot recommend Addison Design Build highly enough.

We are very pleased with the transformation of our basement renovation of a 100+ years Danforth house, which included a full gut of our entire space, structural work, addition of a new bathroom and laundry room in 3.5 months. We were seeking a design-to-build company, and the service that Addison provided met all our needs from beginning to end. In particular, Loren was an excellent project manager who handled all our questions and concerns (big and small) with absolute confidence, patience and impeccable care. Perfect customer service. His team and subcontractors were amazing, skillful and professional, and we would be happy to work with all of them again. We look forward to working with Addison on future projects.

We’ve worked with a number of different contractors over the years and Loren was by far the best. We hired Addison to do a second floor master bedroom/bathroom and ground floor kitchen addition. They stayed on time and on budget, the quality of workmanship was great and any deficiencies were promptly dealt with. Loren was very considerate and patient when discussing any particular issues or questions we had with the renovations. Communication was clear throughout the process and he gave us regular updates. We’re very happy with the end result and wouldn’t hesitate to recommend Addison. We’d definitely use them again.

We hired Addison Design and Build for a full home renovation and had an exceptional experience from start to finish. From our very first interaction, their team stood out as the most responsive, professional, and attentive we spoke with. That early impression gave us immediate confidence moving forward. The entire process was well structured and thoughtfully managed. Communication was clear and consistent, expectations were set early, and decisions were handled efficiently. The renovation progressed smoothly and without unnecessary stress. The level of craftsmanship throughout the home is outstanding. The attention to detail is evident in every finish, and the final result exceeded our expectations in both quality and execution. The trades on site were courteous, highly professional, and respectful of our home and our neighbours. The site was kept clean and well organized at all times. Loren led the project with a calm and precise approach. His attentiveness and coordination ensured the renovation ran seamlessly and made the experience far more enjoyable than we anticipated. We are absolutely thrilled with how everything turned out and would not hesitate to recommend Addison Construction to anyone looking for a high-quality, dependable renovation team.

We worked with Addison design on a major project for our home in the spring and were so pleased with the pace and quality of their work. We were able to complete a full basement Renovation (including underpinning and digging out 2+feet) in less than 4 months from permitting to finished product. Loren was great to communicate with and working with anyone else we had on site. He also dealt with any minor problems very professionally. We would definitely work with them again and recommend them to anyone doing a major project in Toronto.

We worked with Addison Construction for over a year to bring our dream home to life in Playter Estates—and we honestly couldn’t be happier with the result. It was a major renovation: full gut, back addition, third-floor addition, and we even lowered the basement to make it more functional. What really stood out was how well the team worked with their architect and interior designer. The whole design process felt smooth and collaborative. The architect had some amazing ideas for how to use the space more efficiently, and the designer brought everything together in a way that felt thoughtful and cohesive. A project of this size can definitely feel overwhelming, but Addison made it feel under control the whole way through. They were organized, professional, and always available to talk through any questions. Their trades were great too—skilled, respectful, and they kept the site surprisingly clean, which both we and our neighbours appreciated. Seeing our home come together has been such a rewarding experience. We’re incredibly grateful for the care and attention that went into every detail. If you’re looking for a contractor who genuinely cares and partners with great designers, we highly recommend Addison Construction.

This was our first time doing a home renovation and we are thrilled with the end result and overall experience. My wife and I have never undertaken such a large project like this before and we weren't exactly sure where to start. We researched and met with over a dozen Design and Build firms across the city. From the first interaction with Addison Design and Build/Loren(Project Manager), we appreciated how attentive he was, understood our vision and walked us through the process using practical examples. After reviewing all the competitive bids, it was clear that Addison was the best choice for our family. We did a complete home renovation of our 35+ year old rowhouse down to the studs, roughly 3,000 square feet across three floors. This was a 9 month project that was completed almost 2 months early, without sacrificing quality and completing all items requested. Loren was great to work with. He was always available when you needed him, communicated frequently, and wanted to make sure everything was perfect for us. If there ever was a problem, Loren thought through a solution. Some of the big changes we completed were removing internal walls to make the main floor open concept, creating a 10 foot window/door at the back of the property, adding resilient channeling in the ceilings, custom cabinetry, new stairs, new front door, new skylight, and upgraded electrical and plumbing to name a few changes. Overall, we've been very happy with our decision and will definitely consider Addison Design and Build for our next project.

When we decided to build our dream home in Little Italy, we knew the narrow lot and tight city regulations might make things tricky. But from the very first meeting, Addison Construction put our minds at ease. They listened to our ideas and managed to fit everything we wanted into a design that feels open, stylish, and perfectly tailored to our family. What really impressed us was their attention to detail—every inch of space was carefully thought out and beautifully finished. Throughout the construction process, they kept us in the loop, checked in on our preferences, and made sure we felt comfortable asking questions. They truly went above and beyond to make our vision come to life, and even offered creative solutions to maximize our limited space in ways we never would have imagined. Now that we’re settled in, it’s hard to believe this bright, modern, and surprisingly spacious home was once just a cramped city lot. We’re so grateful for the Addison Construction team. Their professionalism and genuine care made what could have been a stressful project feel exciting and rewarding. We can’t recommend them enough for anyone looking to build a unique home in a tight urban setting!

When we bought our semi-detached in the Beaches, we knew it needed major work—but we had no idea how challenging some of it would be. From underpinning the basement (which involved unexpected complications with older plumbing and some water leakage) to fully gutting the main floor, Addison Construction tackled each curveball with professionalism and clear communication. They kept us informed about necessary adjustments to our schedule and budget when hidden issues popped up, which really helped us feel more comfortable despite the upheaval. The new basement is unrecognizable—bright, dry, and with the extra height we desperately wanted. On the main floor, they installed a gas fireplace that ties the living space together beautifully, and we couldn’t be happier with our new kitchen—especially the hidden appliances in the pantry, which keep everything looking tidy and streamlined. We also can’t forget the second-floor headache: leveling out a master bedroom floor that was so crooked it felt like a funhouse. Addison handled that problem without batting an eye, and now it’s perfectly even. Of course, this kind of reno wasn’t without dust, noise, and a few stressful moments, but Addison’s team stayed on top of each snag. They were proactive with scheduling, kept a clean worksite, and even smoothed things over with neighbors when construction ran a bit later than expected. When all was said and done, they delivered a home that’s both modern and full of character. We’d absolutely recommend them to anyone ready to take on a big renovation, especially in an older home that might hide a few surprises.

We recently completed a major renovation project with Addison Construction in the Beaches, and the experience was nothing short of outstanding. We worked with the team over a period of 8 months and engaged them to renovate a three-story duplex, which included updating two existing units that were in decrepit shape and creating an entirely new unit, transforming the property into a stunning triplex. One of the most challenging aspects of the project was the underpinning, and we leaned on Addison for their expertise and trusted them to undertake this challenge for their In-house underpinning team. This meant that everything—from the foundation work to the final details—was managed by their skilled professionals, giving us peace of mind throughout the entire process. Throughout the renovation, the team was highly responsive and always kept us updated on progress. Any questions or concerns we had were addressed promptly, and we always felt confident in their expertise. The work was completed with impeccable craftsmanship, and the final result exceeded our expectations. The new unit turned out beautifully, and the updates to the existing units have truly transformed the entire building. The triplex is now a modern, functional space that will serve our needs for years to come. We are incredibly grateful to the Addison Construction team for their hard work, professionalism, and dedication to quality.

We had an amazing experience working with Addison Construction on our home renovation. They completed a main floor addition, basement walkout, exterior landscaping, and a beautiful new fireplace that completely transformed our space. The brickwork, in particular, is stunning and added so much character to our home. From the start, the team was professional, respectful, and easy to work with. During the design phase, they were flexible and creative, providing clear plans and visuals that made it simple to picture the final result. Communication throughout the project was excellent—they kept us informed every step of the way and were always available to answer questions. The team took great care to make sure everything was done right and were patient through out the entire process. If you’re looking for a honest, reliable contractor who provides exceptional craftsmanship - look no further!
