Home Extension vs Home Addition – What’s the Difference?

Many homeowners mix up home extensions and home additions, but they are actually different:

Home Extensions

A home extension adds more space to your home by building outwards. This is great for:

✔ Bigger open-plan living areas

✔ Larger kitchens, dining, and entertainment spaces

✔ Smooth indoor-outdoor connections

Home Additions

A home addition adds levels instead of expanding outward, creating extra rooms or floors. This is great for:

✔ Adding a second floor for growing families

✔ Creating new bedrooms, bathrooms, or a home office

✔ Making the most of smaller lots

💡 Unsure which option is best for your home? Our expert consultants can help you choose!
