Second Storey Extension

Second storey floor extensions are a great way to add more rooms and space cost effectively, and can considerably increase the value of your home.

A second storey extension can be converting an existing roof or attic space to functional storage, or more involved such as adding additional bedrooms, bathrooms, balconies and even living space.

As the price of land increases more people are maximising on their investment by building up. Costs will depend on the materials and extent but can range from $2,000 to $5,000 per square meter. An average second storey floor extension will cost between $80,000 and $250,000.
