Structural design for changes to your home
We design structural house modifications for St. Catharines homeowners, including new openings, stairs, altered walls and framing. Our work explains what can remain and the supports needed for your planned home changes.
Detailed service overview
An opening, relocated stair or changed support can affect more than the visible area. We assess the relevant walls and framing, then design the connections and supports needed for your house modification.
Understand the structural work needed around the alteration you have in mind.

Support details where a doorway changes the surrounding wall construction.
Design for cutting, moving, or changing an opening in a floor.
Assessment of the supports affected by a particular wall alteration.
Modifications to joists, beams, or other supports around the proposed work.
Review of whether an existing support can be moved, replaced, or reinforced.
Structural details for specific changes to the roof or its supporting construction.
We review the changes you want to make and the plans or information already available.
We review the building or site information and design the structural elements your project needs.
The agreed package explains the designed members, supports, and connections.
Any included permit responses, contractor questions, or design revisions are handled as the project progresses.
Homeowner questions
We assess structural changes to openings, stairs, walls, floors, roofs and existing supports. The work can be one alteration or part of a wider renovation; the design follows the construction affected by the plans.
A wider opening may be possible after the wall and supporting construction are assessed. The header, side framing and supports beneath need consideration rather than treating the door dimensions as the only constraint.
We can assess a stair position and design the framing around the required opening. Interrupted joists need replacement support, while closing the old stair opening may also need new members and connections.
Yes. A local alteration can redirect loads into supports outside the area being changed. A new opening can increase loads at its ends and require assessment of the foundation below those bearing points.
We consider retention where the existing construction remains suitable for the proposed alteration. Loads, condition and connections matter; finishes may need opening if they conceal information required for the structural design.
A proposed layout and information about existing framing provide the starting point for assessment. Opening dimensions, stair positions and available house plans identify affected members, with measurements needed where the details remain uncertain.
It explains the members, bearings and connections required to support the proposed modification. Drawings can show removed, retained and new framing, including construction beneath the altered area where its loads change.
Changes can be reviewed, but their structural effects need checking before earlier details are reused. Moving an opening changes bearing positions even if the width stays the same, potentially affecting support elsewhere in the wall.
