Home Additions Designed Around Your Existing Home

Home addition costs range from $120,000 for a modest rear addition to $350,000+ for a full second or third storey addition with premium finishes. Cost depends on square footage, complexity, structural requirements, and finish level. We provide detailed pricing once the project scope and requirements are defined.

Most home additions take 3–6 months from permit approval to completion. Second and third storey additions with significant structural changes can take longer. Permit processing typically adds 3–5 weeks depending on the complexity of the project.

It depends on the extent of the work. We work to minimize disruption to your living space, but for larger additions or during certain construction phases, moving out may be recommended due to site hazards, noise, and dust. We discuss the timeline and expected disruption in detail before we begin so you can plan accordingly.

Zoning requirements vary by municipality and property. Setbacks, lot coverage, building height, and other requirements can affect what can be built, and some projects may require a minor variance. We review the applicable zoning requirements as part of determining feasibility.

Yes, but there are structural considerations unique to semi-detached homes the shared party wall, matching the neighbouring roofline, and vibration management during construction. We have extensive experience with semi-detached additions across our service area.

That's exactly what our free consultation answers. We check your current lot coverage, zoning setbacks, existing structure, and soil conditions during the site visit. We give you a clear go / no-go before you spend anything on design or permits.
