How to start my building project?

You need to determine what you are allowed to build (how large, how high & where on your property).
Gather site info, lot size, building size, accessory buildings, septic & well (if applicable) & shoreline.
Schedule a meeting with your local planning official (not the building inspector) to determine what you can do.

Or meet with your local full-service designer, D&O can help with that. give us a call 705 549-8800. We service a large area and can help you no matter where in Ontario you are.
