Open-Concept Renovation in Richmond Hill

Taking down the walls between kitchen, dining and living rooms changes how a house feels more than any finish. When those walls hold the house up, it has to be engineered. In Richmond Hill, the housing runs from older homes around Mill Pond to large executive houses in Bayview Hill and South Richvale.

Before you start

What to know.

Load-bearing walls
A load-bearing wall can be removed, but it is replaced by a beam sized by an engineer, with posts and footings carrying the load to the foundation. This needs a building permit.
What is inside the wall
Walls often hide plumbing stacks, heating ducts and wiring. Finding a new route for them is frequently the real work.
The floor underneath
When a wall comes out there is a gap in the flooring. Matching or replacing the floor across the new room should be part of the plan.
