Second Storey Addition Cost in Vancouver 2026: Complete Guide
Adding a Second Storey to Your Vancouver Home
A second storey addition is the most transformative — and complex — renovation you can do to a Vancouver home. It doubles or nearly doubles living space without changing your footprint, which matters greatly on Vancouver’s small urban lots.
