Serving Toronto, Richmond Hill, Vaughan & the GTA
Portfolio
Expand your living space with architecturally integrated additions across Toronto and the GTA. From second stories to bump-outs—we handle zoning, permits, and structural engineering.
Toronto and GTA zoning is complex. We research your property's specific requirements before designing—avoiding costly revisions during permit review.
Second stories and major bump-outs require structural expertise. Our engineering partners design load-bearing solutions that meet Ontario Building Code.
A quality addition looks like it was always part of the original home. We match rooflines, cladding, windows, and foundation details for a cohesive result.
Architecture, engineering, permits, and construction under one contract. No finger-pointing between separate designers and contractors.
Permit timing is the primary variable. We sequence submissions strategically and build schedule buffers into our project planning.
Every worker on your addition is WSIB-covered. We carry $5M liability insurance and are fully compliant with Ontario construction regulations.
From modest bump-outs to complete second stories—AVL delivers GTA homeowners more livable space.
Add a full upper floor or expand an existing second story. Requires structural engineering for load transfer, new stairs, and often roof reconstruction. Our team handles the entire process from design through final inspection.
Extend the main floor or basement at the rear of the home. Ideal for expanding kitchens, creating breakfast nooks, or adding a home office. Foundation and waterproofing details are critical—we get them right.
Expand laterally where lot depth is limited. Common in urban Toronto neighborhoods with shallow lots. We navigate setback variances and maximize usable floor area within zoning constraints.
Glass-enclosed sunrooms and all-season porches add living space while connecting indoor and outdoor areas. Requires HVAC integration and proper thermal performance for year-round use.
A home addition is a significant investment. AVL provides honest feasibility assessments, transparent budgeting, and one accountable team from concept to completion.
