Second Storey Additions
& Extensions Sydney

Adding a second storey extension to your existing home is a great way to maximise living space without sacrificing your outdoor space.

When Should You Consider a Second Storey Addition?

Growing Family Needs

As families expand, extra space becomes essential. A second-storey addition adds bedrooms, bathrooms, or play areas, allowing your family to stay comfortable in the same home.

Limited Land Space

When ground floor extension is not possible, a floor addition makes sense. A second storey helps you gain valuable living space while preserving your square metre or garden.

Increasing Property Value

Second-storey additions significantly boost your home’s market value. More space, better functionality, and modern design features appeal to future buyers and increase long-term resale potential.
