Home additions.
An addition is more house on the same lot: a new kitchen and family room across the back, a side addition for a main-floor bedroom, or two storeys of new space where the lot allows. The hard part is the tie-in, where the new foundation meets the old, the new roof meets the existing one, and the floors line up to the millimetre. That is where Savino Construction earns the job.
Concept imageryOn the drawing.
Zoning check of setbacks and lot coverage before design so the addition fits the lot
Engineered drawings and a rendering of the addition inside and out
Building permit filed and followed by us, with any conservation review handled first
Excavation, new foundation, framing, roof and envelope tied into the existing structure
Openings cut into the old house under shoring, with beams sized by the engineer
Mechanical and electrical extended, finishes from the catalogue, a deficiency walk and a written warranty
Drivers, not figures.
| Driver | What we look at |
|---|---|
| Floor area and storeys | A single-storey rear addition and a two-storey one share a foundation but not much else. |
| The tie-in | How much of the existing rear wall opens up, and whether the roofs meet cleanly or the old roof is reworked. |
| Foundation type | Full basement under the addition, crawl space or slab, and what the soil and the water table allow. |
| Lot constraints | Setbacks, lot coverage, a ravine or conservation edge, and how a machine reaches the back yard. |
| Finish level | Kitchen and bathroom scope inside the addition, chosen from the catalogue. |
No price per square foot on this site. The zoning check and the drawings set the number, and the number holds because of them.
Paper first.
- A building permit with engineered drawings is required in every GTA municipality.
- Setbacks and lot coverage come from the zoning by-law; a design outside them goes to the Committee of Adjustment first.
- Lots inside a conservation authority's regulated area need its review before the permit.
- Heritage listing adds a review of anything visible from the street.
The paperwork wall: WSIB, insurance, licences, the HCRA status and the warranty, on one page and dated.
If the lot has depth and the by-law allows the coverage, a rear addition keeps you in the house during most of the work and opens the plan to the yard. If the lot is narrow, the second storey is the addition of choice. We tell you which at the site walk.
For most rear and side additions, yes. The addition is built as a shell before the wall between it and the house is opened, and dust walls seal the route. We tell you what to expect before you sign.
Not if the roof, the cladding and the window pattern are drawn to match or to contrast on purpose. The rendering shows the whole house, old part and new, before you commit.
Yes, in every GTA municipality. An addition changes the footprint and the structure, so it needs a building permit with engineered drawings, and often a zoning review first. We prepare the drawings and file it.
