Not only is it visually stunning, but it is also compatible with any location in the beautiful province of Ontario.

With its wide front porch, this floor plan encourages you to enjoy the view of the peaceful countryside or vibrant city. You can enjoy the cold winter nights wrapped in a blanket while taking in the fresh air. Furthermore, the covered porch at the front of the house has an interesting roofline, being great for sitting outside and enjoying the view.

Now imagine yourself enjoying a hot cup of coffee, watching the sunrise or sunset from your dream home.


This plan would be suitable for small families or those looking to create a rental unit in their basement. The 1 bedroom, 1 bathroom apartment in the finished basement has an open concept design in the living area. This is great for tenants who prefer a private accommodation. It can be used as single-family home, with the option to invite friends or family to stay overnight in the spacious basement, or be occupied as two separate units!

For those who enjoy dining outside in the warmer months, a back deck could be added, so long as there is enough space on the lot! This addition would be a perfect place to host small gatherings or barbeques with your close friends and family. Indeed, endless possibilities come with Plan 21-0040.



The unique feature of this design plan is the 1 bedroom, 1 bathroom apartment in the finished basement. The apartment allows for privacy and independence while also being a source of extra income when used as a rental unit.
