Home Additions
Seamless Home Additions Across Vancouver Island & Gulf Islands
At Island Heights Construction, we create beautifully integrated home additions for families across Nanaimo, Duncan, Mill Bay, Tofino, Port Alice, Cobble Hill, Cowichan Bay, Parksville, Nanoose, Ladysmith, Lake Cowichan, Port Alberni, Courtenay, and the Gulf Islands. Whether you’re expanding for comfort, functionality, or future resale value, we’re here to deliver thoughtfully designed spaces that feel like they’ve always been part of your home.
Why Choose a Home Addition Instead of Moving
Moving can be stressful and expensive. With a home addition, you can:
Stay in your current neighbourhood and school district
Avoid real estate commissions, closing costs, and moving fees
Add meaningful square footage tailored to your lifestyle
Boost your property’s market value with a long-term investment
Clients from Parksville to Courtenay love the idea of growing their space without leaving their community.

Frequently Asked Questions
Do I need a permit for a home addition?
Yes. Every municipality on Vancouver Island and the Gulf Islands requires permits. We take care of the entire permitting process.
How big can my addition be?
Size depends on local zoning laws, lot coverage allowances, and existing building placement. We assess this during the site review.
Can you match my existing finishes?
Absolutely. We source materials to blend your addition seamlessly with the original home—inside and out.
Will construction disrupt my household?
We work to minimize disruptions with clear scheduling, dust control, and safety protocols. Many projects allow you to remain in your home during the build.
What if my home is on a slope or near the shoreline?
We’re experienced in working with varied terrain, including hillside lots and floodplain properties. Structural engineers ensure the addition is stable and safe.
