Building more
home, the right way.
More square feet,
same home.
The hardest part of a home addition is making it not look like an addition. Rooflines that meet at awkward angles. Siding that does not quite match. Floor heights that step down where the old house ends and the new begins. The bolted-on look is the result of a build that focused on permits and framing, but never solved for integration.
We approach additions the opposite way. Integration first. We study the existing home before we draw a single line. Roof pitches, eave heights, brick courses, window proportions, floor levels. The addition is designed to extend the home rather than interrupt it.
Bump-outs to expand a kitchen or bathroom. Single-room additions for a primary suite or family room. Second-storey additions that double a home's footprint. Rear extensions that open the back of the house to the yard. We deliver all of them.
Permits to finish.
An addition is a small house attached to a larger one. Every system has to be planned, permitted, built, and finished to the same standard.
Permits & Engineering
Site plans, structural drawings, building permits, and zoning approvals. Engineering for foundation and load paths.
Foundation Work
New footings, foundation walls, and slabs as required. Tied properly into existing structure.
Framing & Enclosure
Wall framing, roof structure, sheathing, and weatherproofing. Sealed and insulated to current code.
Mechanicals Integration
HVAC ductwork, plumbing rough-in, and electrical wiring tied into existing systems and panel.
Interior Finishes
Drywall, paint, flooring, trim, doors, hardware. Matched to the existing home or refreshed throughout.
Exterior Matching
Siding, brick, stone, roofing, soffit, fascia. The exterior reads as one house, not two stitched together.

What an addition costs.
Honest ranges based on additions we deliver across Halton Hills and the GTA.
Small Bump-Out
8 to 12 foot extension on existing room. Foundation, framing, and finishes.
Single-Room Addition
New bedroom, bathroom, family room, or primary suite added to the home.
Second-Storey Addition
Full second floor added to a single-storey home. Multiple bedrooms and bathrooms.
Major Extension
Multi-room rear or side extension. Often combined with interior renovation.
What affects the final number: addition size, foundation depth, structural complexity, mechanicals integration, exterior matching, finish tier, and zoning or heritage considerations.
For your addition.
Additions are won or lost on integration. The exterior, the rooflines, the floor heights. Our additions look like they were always there.
Integration-First Design
We measure rooflines, eave heights, brick courses, and floor levels before drawing the addition. The new build matches the old before construction starts.
Permits & Zoning Handled
Site plans, building permits, zoning variances if needed, heritage approvals where applicable. We manage every municipal interaction so you do not have to.
Foundation Done Right
Proper footings, proper tie-ins to existing foundation, proper waterproofing. The foundation you cannot see is the part that determines whether the addition lasts.
Live-In Strategy
Most additions can be built while you stay in the home. We seal and isolate the build zone. You keep your life. The new space is ready when it is ready.
Common questions.
The questions homeowners ask when planning an addition.
A small bump-out runs 8 to 12 weeks of build time. A single-room addition takes 12 to 20 weeks. A second-storey addition can run 20 to 32 weeks. Permitting and design phases add 2 to 4 months upfront. We provide a detailed schedule before contract signing.
Sometimes. Setbacks, lot coverage, height limits, and heritage rules all vary by municipality. We assess zoning compliance during the design phase. If a variance is needed, we manage the application through the Committee of Adjustment.
For most additions, yes. We seal the construction zone with temporary walls and weatherproofing. The existing home stays heated, cooled, and protected from dust. There will be a few days of disruption when we connect the new mechanicals to the existing systems, which we plan around your schedule.
Yes, intentionally so. We source matching brick, siding, roofing, and trim where possible. For older homes where exact matches do not exist, we use complementary materials that read as one home. The detail at the seam between old and new is where most additions fail. We focus on it.
We assess load capacity during the design phase. Sometimes the existing furnace, AC, and panel can carry the addition. Sometimes they need upgrades. Whether it is a panel upgrade, a second zone, or new ductwork runs, we account for all mechanicals in the original quote.
Single-storey rear additions on a slab tend to be the most cost-effective per square foot, especially when they extend an existing room rather than adding a fully separate one. Second-storey additions cost more per square foot because they require structural reinforcement of the existing first-floor walls and foundation.
When the addition was finished, we could not tell where the old house ended and the new one began. The exterior looks like it was always there. That alone tells you the level of attention to detail.
