Home Extensions Melbourne: Single‑Storey vs Double‑Storey Explained

Michael Worth Projects specialises in home extensions in Melbourne, providing expert design and construction services that enhance comfort, space and value.

Families increasingly choose home extensions in Melbourne to accommodate growing households, improve comfort, and enhance property value. Homeowners often weigh the benefits of adding practical single-storey spaces against the long-term value of double-storey designs. Comparing these options ensures the right investment for lifestyle needs today and property growth in the future.

What is a Single-Storey Extension?

A single-storey extension is often the simplest and most direct way to expand living space. These projects add functional rooms at ground level, such as a larger living area, an extended kitchen, or even a seamless open-plan design. For families seeking cost-effective solutions, this approach is one of the most attractive forms of residential extensions.

The benefits of single-storey additions lie in their straightforward construction and affordability. With less structural complexity, the build process is faster and less intrusive, allowing families to return to everyday life sooner. However, these projects require adequate land size, making them ideal for properties with larger backyards. When land is limited, alternatives like vertical property expansions may be more suitable.

Benefits of Double-Storey Extensions

Double-storey extensions are a powerful option for families looking to maximise available space. By building upward instead of outward, these projects provide additional bedrooms, home offices, or entertainment areas without reducing outdoor living zones. For many Melbourne households, vertical expansion represents a long-term investment in both functionality and value.

The advantages are clear: a double-storey design preserves precious garden or backyard areas while offering a significant increase in usable space. In many cases, such house additions can substantially boost resale value, making them particularly appealing for owners planning to stay in their property for decades. The main considerations, however, are higher upfront costs and longer construction timeframes. This type of extension is also more technically demanding, requiring stronger foundations and expert planning.

Essential Factors When Choosing a Home Extension

Selecting between single-storey and double-storey extensions requires careful planning. Homeowners should weigh financial resources, lifestyle needs, and property constraints before committing to a design. The following considerations help guide an informed decision:

•  Budget: Single-storey projects generally have lower upfront costs, while double-storey extensions require larger financial commitments.

•  Space: Properties with ample land can benefit from ground-level builds, while compact blocks may favour vertical options.

•  Lifestyle: Families must consider accessibility for all members, long-term functionality, and future household changes.

•  Council Approval: Melbourne councils often require planning permits, so understanding regulations is essential before work begins.

•  Design Aesthetics: Extensions should harmonise with the existing structure to ensure a cohesive, attractive result.

The City of Melbourne website provides different guidelines related to the Code of Practice for Building, Construction and Works (as incorporated under Council’s Activities Local Law 2024 – commenced 23 May 2024).
