What’s Included in a Home Addition in Calgary

A home extension, more commonly called a home addition in Calgary, adds new heated square footage to an existing house rather than reworking the rooms already inside it. Ultimate Renovations sizes the scope around where the new space sits relative to the rest of the home.

At minimum, expect new windows, new siding, and the extension or creation of a roofline. New soffit, fascia, and a gutter extension usually follow. It’s not uncommon for home additions to trigger a general exterior update, since the new materials can either be matched to the existing facade or set the direction for a new look. The interior is then finished with flooring, electrical, HVAC, and in some cases cabinetry and plumbing.

Testimonials

"The quality of the workmanship is stellar, right down to the smallest details."

It's a shame it's not possible to give a rating with more than 5 stars! We could not be more pleased with the incredible job that the Ultimate Renovations Team did with our full main-floor renovation! It's the experience and the depth of the team that really shines- beginning with the designers and their amazing electronic tools that provide detailed renderings that help so much to "see" how things will look. Then the skill and experience of the project manager, the field crews and their trades takes over and brings the dream to a reality. The quality of the workmanship is stellar, right down to the smallest details. We were out of the country while most of the work was being done, but regular Zoom meetings made us feel like we were there. Thanks to the entire Ultimate team for delivering our "new home"! - David H

"...we are thrilled with how our experience with Ultimate turned out."

After a winter in our 'new' basement, I can say we are thrilled with how our experience with Ultimate Renovations turned out. We were wanting a warmer, more inviting space, and Ultimate Renovations helped us get there. From our first meet and greet where we shared our ideas, Ultimate helped guide us with what could work, what wouldn't work and what would definitely work. Throughout the process we never felt rushed or pressured, and it was Ultimate that was accommodating with their time when we had to delay the start date due to illness in our household. During construction we were impressed with how well the team cleaned up at the end of each day. Ultimate did a great job to try and keep dust and debris levels down. Another highlight of our experience was just how easy it was to reach out if needed, be heard, and any question or concern was taken of quickly. If needed in the future, we would look at using Ultimate again, and we would recommend Ultimate to anyone.- Shane M

"We are over the moon happy with our renovation."

Ultimate Renovations undertook a major renovation of our Willow Park (Calgary) bungalow. This reno included our main floor (kitchen, dining room, living room, front entry), back landing and two bathrooms. Paul, Danny, Darryl, Miriam, Keith, Corrine, Todd, Shay and team were absolutely fantastic to deal with. Ultimate Renovations staff are very professional and they guided us through the renovation process with innovative design concepts, appropriate timelines and schedules, excellent quality product and craftsmanship with in house trades and technical team, beautiful custom cabinet and railing design, plus they delivered product and installations on time and within budget. We are over the moon happy with our renovation. Thank you Ultimate for making our house the home of our dreams.- Dale & Dana K

"We were worried our plan was a bit too 'small potatoes' for them but they treated us like we were the most important customers!"

It is not everyday that you find a company that is true to their word and run well. So when it does happen on the rare occasion, I think it's important to let others know. My husband and I chatted about moving our kitchen island and expanding our space. We contacted Ultimate Renovations and were so impressed by their professionalism. Both Danny and Paul came right to our home to meet and discuss. We were worried our plan was a bit too "small potatoes" for them but they treated us like we were the most important customers! After hearing our ideas and offering some sage wisdom, they called us back and presented us with a detailed report outlining all procedures and costs. Nothing was left out and we left that meeting with a very clear understanding of exactly what the job would entail. We appreciated their thorough and transparent approach and wouldn't hesitate to recommend them to anyone considering a home reno. - Candice R

"The skill and workmanship of the workers is unquestioned."

After almost 20 years in the same kitchen, my wife and I decided it was time to upgrade from the old cabinetry and open up some space. We had several renovation companies give us quotes but Ultimate gave us ideas. We ended up changing the entire kitchen layout and we're ecstatic with the results. The skill and workmanship of the workers is unquestioned. Every detail is observed. One of the most positive experiences was the good nature of all the contractors coming into our home. The only problem that I have with our new kitchen and living space is that we can't keep the kids out of it! When the time comes to renovate our basement, Ultimate Renovations will be getting a call.- Don M

"We are very pleased with the final result and stress free process."

"We would definitely not only turn to Ultimate again for a renovation project but also highly recommend them to friends."

From the first meeting to the last step of our outdoor living space project, Ultimate's team delivered a professional as well as friendly service. Our ideas and questions were always responded to respectfully and promptly. The final product is much more than we'd originally imagined, providing a beautiful and welcoming additional space to our home and backyard. We would definitely not only turn to Ultimate Renovations again for a renovation project but also highly recommend them to friends.- Patti T

"We highly recommend this Calgary-based company for all your quality renovation needs."

My wife and I were first introduced to the superb design and workmanship of Ultimate Renovations 20 years ago (2004) when they renovated our award-winning bungalow. It was a 4-month tear down and rebuild project and completed on time and on budget. To date the project has stood the test of time for quality and appearance. In the last two decades, we have hired Ultimate 4 more times for major projects including converting the inclosed basement to a walkout, two upgraded bathrooms, a complete rebuild of a lower laundry room and a most enjoyable 400 sq. foot outdoor living space with TV, BB-Q, cooktop, wood burning fireplace and overhead gas heater. We spend ample time outside for 6-7 months per year with this addition, dismissing the chilly Calgary summer and fall evenings. Of all the five jobs, we recently had the first call back for an issue under the laundry room floor. Although it was completed 4 years prior, Ultimate was quick to send out a crew and do a one day repair, hassle free and no charge. Once again Ultimate Renovations came through for us with their always professional and friendly employees. We highly recommend this Calgary-based company for all your quality renovation needs.- Randy K

"Their process from start to finish is the best I've experienced and I've done a lot of renovating over the years."

"They truly helped to make the house we reside in, our home."

We were so pleased with the work of Ultimate Renovations years ago; they were our definite go-to when we considered our recent bathroom renovation. The quality of workmanship was top-notch, and we are so glad we did. From the large items right down to the little details, the folks from Ultimate made sure we were satisfied with the work done. We would and continue to recommend Ultimate to our friends and neighbours for interior and exterior renovations. They truly helped to make the house we reside in, our home.- Jo M

"We would highly recommend Ultimate as a company to work with."

"Do yourself and your family a favour and get a quote from this outstanding company."

Your search for a renovator is over! Seriously, do yourself and your family a favour and get a quote from this outstanding company. While this was by far our biggest undertaking, we had already used other companies to renovate our kitchen and main bathroom. While very satisfied with the results of those projects, the process pales in comparison with Ultimate Renovations. Bar none, this is the finest company and group of people we have ever had the pleasure to work with! Their quote is highly detailed (and they truly listen to what you want). I couldn't get over how much of the stress is removed by dealing with such an impeccably organized, professional group! It's your home, why not make your renovation a pleasure by choosing to work with Ultimate Renovations!- Chris A

How long do home additions take to complete?

There’s no one size fits all answer here. Because they involve both exterior and interior components, timing is everything which is why a well planned project is so important. It’s best to call us and chat about your needs to get an estimated timeline on the scope of your unique project.

Do I have to update my whole house if I build an addition?

No. A home addition can either match the existing house or set a new direction for it, inside and out. Ultimate Renovations designers work through the selections process with the homeowner to decide which way the finishes, siding, and roofline go.

How should I prepare for a home addition?

Decide whether you plan to match or update the look of your new space to the old one, both inside and out. This is one of the biggest design questions to answer, and will impact all remaining stylistic choices throughout your renovation. We can help you prepare for your project, as apart from assisting homeowners in Calgary, we’ve completed major home additions in Edmonton too!

Is a home extension the same as a home addition?

A home extension and a home addition describe the same work: new heated square footage built onto an existing house. Ultimate Renovations uses the term home addition, which is standard in Calgary and across Alberta, for kitchen bump-outs, master retreat expansions, home offices, hobby rooms, mudrooms, and extra garage bays.
