Frequently Asked Questions

A custom home addition increases your living space by building upwards, adding another floor level without sacrificing yard space. In contrast, a home expansion extends the footprint of your house outward, taking up more of your yard.

To add to an existing house, you'll need to hire a team of licensed home addition contractors, structural engineers, and architects to ensure safety and compliance. You'll also need to cover costs for construction demolition, building permits, and materials. 

Our team deals with this process, including city bylaws and getting plans drawn up. More information on allowable square footage and floor space ratios (FSR) can be found through additional resources.

We are SOO happy with the work that Markley Construction did for our warehouse!
