What's the difference between single-storey and double-storey extensions?

Short Answer

Single-storey extensions are more cost-effective and quicker to build, whilst double-storey extensions maximise space on smaller blocks but involve greater complexity and cost.

Long Answer

Single-storey extensions expand your home horizontally, adding rooms at ground level. They're typically more cost-effective, have shorter construction timelines, and cause less disruption to your daily life. These extensions are perfect for creating open-plan kitchen and dining areas, additional bedrooms, or luxurious outdoor entertainment spaces.

Double-storey extensions build upward as well as outward, maximising space on smaller blocks whilst preserving garden areas. They offer greater flexibility for creating distinct living zones, such as family areas downstairs and private retreats upstairs. However, they require more complex structural engineering, longer construction periods, and generally involve higher costs.

The choice between single and double-storey depends on your block size, local height restrictions, budget, and lifestyle needs. Double-storey extensions often provide better long-term value by maximising floor area without sacrificing outdoor space, particularly important in Melbourne's prestigious inner suburbs where land is at a premium.
