Residential Homeowners
Adding on at the back, opening up a layout, or going up a storey? We design the change to work with your existing home and Calgary's rules.

Changing a home you already own comes with surprises behind the walls. Tricor plans renovations and additions in Calgary by starting with what is actually there, then drawing the changes so they are buildable, code-compliant, and ready for a permit. We have worked on Calgary homes since 1985.
Renovations & Additions
A renovation or addition lives or dies on what is already standing. Before we design anything, we look closely at the existing structure, the layout, and the site.
That early read tells us what is realistic, what the addition can tie into, and what the City will want to see. It saves you from designing something the house, or the bylaw, will not allow.

What Tricor helps with
A renovation needs more than a good idea. The existing structure, your layout changes, zoning, and the permit drawings all have to line up before the project goes too far.
We pull that technical and approval side together so your next step is clear and well supported.
We document the current home, structure, layout, and site before any drawings move
We develop a practical direction for the layout, form, and additions.
We plan layout changes, additions, access, and massing with zoning in mind.
We handle drawing revisions and City questions when more information is needed.
