IK Home Improvement INC.
House Extension Professionals in Ottawa, ON
Average rating: 5 out of 5 stars6 March 2017
“The project was the complete renovation of a 30 year old side-split bungalow, including removal of walls to create a modern open look in the kitchen and living areas, the addition of an attic beam to compensate for the wall removals, addition of modern hardwood flooring throughout, and ceramic tiling in entranceway, mudroom, and bathrooms, and complete renovation and update of the bathrooms. Igor's work ethic, knowledge, attention to detail and ability to meet deadlines and budgets were exemplary! His willingness and ability to deliver beyond the original scope of the project without significantly impacting deadlines and budgets was appreciated! I highly recommend this professional!”

Average rating: 5 out of 5 stars25 January 2020
“We had the pleasure of working with Tonya and her amazing team on a project we headed up at the local Ronald McDonald House. To say that we were more than impressed with their professionalism was an understatement. Their team worked closely with us and helped us create the vision we had for the room renovation and the end result was simply magical for any family that now gets to stay in the room. We cannot thank them enough for their quality of work but more importantly their wonderful hearts and dedication to the job at hand. Highly recommend them for any job you may be planning and I know we will be using them again!!”

Glengarry Construction & Design
House Extension Professionals in Ottawa, ON
Average rating: 5 out of 5 stars1 December 2021
“Glengarry Construction & Design did major renovation in our house. We had the basement finished with a new bathroom and living room as the first project. The second project was a total make over of the main bathroom. We could not have asked for better contactors and workers. They designed both projects taking in consideration our wishes, ideas and budget. The work was excellent and it was done rapidly and efficiently. They were very well organized. At the end of the day, they would leave the place clean. Through the renovation, they keep us informed of the progress and the next step to be. They were very professional, respectful and polite while working. Their workmanship skills were remarkable. We are totally satisfied with the work done in our house. The renovations were completed in August 2020 and we are still very happy with the final product. We highly recommend Glengarry Construction & Design for your renovation or new construction.”
Oneway Structural & Construction
House Extension Professionals in Ottawa, ON
Average rating: 5 out of 5 stars19 March 2017
“Oneway did a fabulous job with our guest bathroom. In particular, other renovators had told us it would be impossible to move the fixtures without adding bulkheads in the rooms below -- but Wes was able to do it. Next we hired Wes and crew to redo our master bathroom, including swapping the master bedroom with another bedroom also adjacent to the ensuite. Wes had some problems with project time and budget management on this project, but he came through for us and made things right. In the end, the project looks spectacular -- better than any master retreat I have ever seen. Not only does his crew do a great job, but they are just really nice people. Even as a picky client, I was very pleased with the attention to detail on this job. Thanks!”

Builder FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Ottawa.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions. Finally, choose a reputable house extension builder to bring your vision to life.
