Featured Reviews for House Extension Professionals in Toronto, ON

Dewson Architects
House Extension Professionals in Toronto, ON
Average rating: 5 out of 5 stars7 June 2013
“I hired William Dewson Architects to design a summer cottage in Georgian Bay on a 5 acre island. Our first challenge was to figure out the site plan and where to put the cottage given numerous zoning restrictions and other natural fators. Bill and his team were great to work with throughout the whole process of defining the best site and then brainstorming the design that best suited our family asthetic. Bill's charismatic enthusiasm made our meetings fun and creative, we were all very happy with the end result and thoroughly enjoyed the design experience from start to finish.”
BLDG Workshop Inc.
House Extension Professionals in Toronto, ON
Average rating: 5 out of 5 stars7 August 2013
“We can highly recommend BLDG Workshop with complete confidence. In contrast to the many bumps along the way of our renovation and addition, the design process was exciting and enjoyable. Nathan and his team of professionals were timely and efficient, good at communication, and willing to work with the trades we had hired; however, their best attribute is of course their smart, inspired design! Our favourite part of working with BLDG was the collaborating... they are the experts but they listened to our ideas and were excellent at incorporating our whims and wishes. We will definitely be contacting BLDG the next time we build!”

“We worked with Gloria to re design and re construct a 3,400 square foot home in Riverdale. The results were spectacular in the true sense of the word and a credit to Gloria's innovative and cost sensitive design. We would recommend her highly.”
Lindy Architect
House Extension Professionals in Toronto, ON
Average rating: 5 out of 5 stars13 September 2013
“We engaged Lindy Consulting to provide some plans to renovate the 3rd floor of our house which was an unused portion of our house which contained two bedrooms and which we were using as additional storage space. Our plan was to move our master bedroom to this space and add a full washroom. We met with Steven and Annette to discuss our ideas and how we envisaged the space and our estimated budget. They came back to us the following week with some preliminary sketches that impressed us. We then gave them the mandate to prepare full drawings and once approved by us, they managed the project from completing the drawings, getting them approved, and seeing the project through to completion. We were quite hands-on in the decision making but they truly took ownership of the project and had our best interests in mind throughout. Although we ended up spending more than we budgeted (which was as a result of our decision to upgrade bathroom appliances, flooring etc.), we are really pleased with the final result.”
Geometra Design Ltd.
House Extension Professionals in Toronto, ON
Average rating: 5 out of 5 stars8 November 2012
“I hired Gabriele and his company, Geometra Design in June 2012 to design a 3,500 square foot, 2 storey home that I will be building in south Etobicoke. Gabriele was able to complete concept design, committee of adjustment application and meeting, building permit design and application in less then 5 months. He was able to accomodate all aspects of the building permit requirements, including mechanical engineer, structural engineer and final renderings. His professionism and approach to the project, including deadlines was unsurpassed. He was able to facilitate all my needs, from design to building permit application (which in Toronto in not easy). His knowledge of the new digital building permit application requirements, made my application process very easy. I was told at the City of Toronto building department that most people do not have all the documents in the required format, but my application was perfect. I am very pleased with his work ethic and ability to respond to all requests. He was very easy to work with and I would recommend Gabriele and his company to anyone who is looking for a knowledgable architect, who can take any project from start to finish with ease. I look forward to working with him again soon. Gino C - Wynford Homes Ltd.”
Wanda Ely Architect Inc.
House Extension Professionals in Toronto, ON
Average rating: 5 out of 5 stars31 January 2014
“My husband and I are currently working with Wanda to update the kitchen of our Toronto century home (my estimates below are projected therefore, rather than actual, as the work is not yet complete). Wanda took time to hear our needs and wants and has been expert at helping us to clarify what those actually are. We had been stalled in the decision making stage for years, and within a few short weeks of working with Wanda, she had helped us to come up with a design that we are very happy with. It works for our esthetic and our budget and solved the design riddles that had plagued us. I had seen some other projects that Wanda worked on and whilst I really admired them, I knew my husband and I would be making very different style choices from those clients. I have been most impressed with Wanda's ability to "get" and work with our eclectic and somewhat undefined tastes as well as our thrifty budget.”

EZDimensions - Home Renovation Design to Permits
House Extension Professionals in Toronto, ON
Average rating: 5 out of 5 stars22 December 2014
“We hired Erin back in spring 2012 for our Home Renovation and it was one of the better decisions we made. Our home was built in 1920 and our addition required a well thought out design which Erin was able to deliver and help walk us through. Erin exceeded our expectations from her initial visit to discuss what we were looking for in our addition, right through to the final drawings completion and permit delivery.”

Architect or Architectural Designer 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 Toronto.

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.
