Home Additions project example

01What's Included

Every trade. Every permit. One contract.

We carry the project from first measurement to final clean. No coordinating subs. If the project needs it, it’s in the quote.

01

Architect & design coordination

we work with your architect, or recommend one of three GTA firms we trust to deliver.

02

Zoning, variances & Committee of Adjustment

minor variance applications, neighbour notification packages, and hearing representation.

03

Permits & engineering

building permit, full structural drawings, soil testing where required, and lateral-load engineering for second-storeys.

04

Demolition & temporary protection

careful removal of existing exterior wall, weather protection, and access management.

05

Foundation, framing & roofing

extended footings, structural steel where needed, framed shell tied into existing house, water-tight roof.

06

Mechanical integration

HVAC, plumbing, and electrical extended through the existing house with minimum disruption.

07

Interior finish

drywall, flooring, trim, paint, and full coordination with kitchen or bath built into the addition.

A home addition is half a renovation and half a new build — and twice the choreography of either. You are tying new structure into an existing house that has settled, expanded, and contracted for decades. The work that does not show is what determines whether the addition reads as part of the house in ten years, or as something stuck on the back.

We have learned that the early phases — design, zoning, structural — are the ones that determine whether the project goes well. We invest the time there, and the construction phase rewards us for it.
