Second-Storey vs. Rear Addition: Which Is Right for Your Home?
When a house gets too small, the two most common options are building up or building out. Which one makes sense depends on your lot, your existing structure and how you live.
Second-storey additions
- Add space without using more of your yard
- Require a structural review of the existing walls and foundation
- Usually mean moving out or living with significant disruption during construction
- Are limited by local height and zoning rules
Rear additions
- Often easier to build while the family stays in the house
- Need a new foundation and use up yard space
- Are limited by setbacks and lot coverage rules
- Work well for kitchens, family rooms and main-floor bedrooms
Zoning and permits come first
Both options require a building permit and must meet zoning rules. Some projects also need approval from the committee of adjustment. Check feasibility before you spend money on detailed drawings.
Talk to a builder early
An early site visit helps you understand structure, services and likely costs before you commit to a design. It is much cheaper to change a plan on paper than during construction.
