Innovation & 3D Technology

At our model home/sales office/home away from home, our design and project management team are here throughout the week working on projects, and meeting with current and future clients. We use 3D home modelling software that allows us to walk through your home to get a feel for the space before its built! It is a cool and crucial tool when working out the big details like kitchen design, window heights, and rooflines to name a few. Have a look at our project gallery for samples.

Easy & Flexible

Building for many can be very stressful and overwhelming, but at Bay Builders we make the process easy. Within a handful of meetings, our team can take care of everything from financing, design, project management and all the finishing touches. Our builder packages focus themselves on what is best for you as the homeowner and can be catered to your specific needs. We can get a project started for you, or we can complete your home from foundation to finishes and decor. Its all up to you!

Custom Quality & Selection

Every home is a custom home, whether it’s built in a factory or on your lot. Our in-house design team will guide you from the first sketch, to blue prints, to material selection and finishing touches. You can start with one of our floor plans, or you can bring us your rough plans and ideas for a totally custom design. Finishing materials like flooring, countertops, and more can be sourced locally with our design team, or discovered online. We make sure you get the function and style you deserve.

Fast, On Time & On Budget

Our Guildcrest modular homes could be just what you need if you’re looking for a quality home built fast. We are able to tailor your budget and give you a complete price for your home before the home is even built. Not hindered by weather delays, modular homes are built inside of a factory equipped with the latest technology, tools, and professionals. Bay Builder’s custom built homes feature all of the same quality and care while being built on your property, offering the experience of watching your home come together from the ground up.

Energy Efficient

Any home built to today’s Ontario Building Code standard will be energy efficient, especially during our cold winters and humid summers. Whether it’s factory built or built on site, we offer several energy efficient packages that go above an beyond the standard to give you peace of mind. Our design team is always integrating LEED principles and passive solar design to make your home naturally energy efficient, while also having worked with Geothermal and Solar systems for those looking for an off-the-grid lifestyle.

  • Most people build a new house because they want to. We built a new house because we had to. When a fire destroyed our home in June of 2007, we were overwhelmed by the prospect of building. Bay Builders delivered on their promise to build us a beautiful, solid, energy efficient home. The team turned what started out as a stressful burden into a positive and exciting experience we will never forget. We will always be grateful for their compassion, respect, and skill.

  • From the beginning you assisted us in selecting the floor plan that best suited our needs. You even customized the rooms to accommodate our particular needs. Throughout the entire experience time was taken to listen and address any concerns we may have had. The day the house arrived the entire neighborhood took in the show with much interest and enthusiasm. It gave us the opportunity to meet our new neighbours before we actually moved in.

    Glen & Anita J
  • Never having built a home before we were quite nervous and confused about the whole process. The Bay Builders team allayed our fears and worked with us every step of the way, providing expert advice and assistance which helped us complete the home worry-free. The first home turned out so well we chose Bay Builders when we decided to build a second home for our son, and we could not be more pleased with the outcome. Thanks to the entire Bay Builders Team!

    George, Elizabeth & Phillip T
  • We are very glad we selected a well built Guildcrest home and that we used Bay Builders as both the dealer and general contractor. Our home is beautiful and gets a lot of compliments from our neighbours and it will be our home for many years.

    Chris & Sue
  • Bay Builders provided us with a tremendous amount for support with all phases of one of the biggest undertakings my wife and I had ever taken on. Their professional assistance in the design phase clearly eliminated the need for any changes during the construction phase, and ensured we received the services and functionality expected of our new home.
