At Terramyer, we don’t just build extensions—we help families create the space they’ve always wanted. As a reputed home extension builder in Melbourne, we create seamless additions that enhance lifestyle and property value. Our team understands the significance of a well-designed extension. It adds space, improves functionality, and boosts the aesthetics—three features every homeowner wants. This way, your home can easily adapt to your family’s changing needs.

If you want to expand your living space without leaving the neighbourhood you love, we are here to help! We can add a second storey, extend out the back, or restore the charm of a heritage home. Riding on the back of many successful projects, we’ll tailor all home extensions to suit the layout, lifestyle and budget of the families who live there.

Types of House Extensions We Deliver

Not all homes are built the same, and neither are our extensions. Our expertise with house extensions lets us offer a range of custom options to suit different layouts, goals and property types. These include:

Single Storey Extensions

This is perfect for families who want more space without the hassle of moving. We can expand your kitchen and living area or add a new bedroom.

Ground Floor Extensions

With this option, you can make the most of the existing layout. If you own an older home or property with underused outdoor areas, get this extension.

Second Storey Extensions

If you want to add height, space, and value to your existing space, this is a great alternative. A second-storey house extension is perfect if you don’t want to sacrifice your backyard.

Double Storey Extensions

Boost functionality and street appeal with double-storey extensions. It’s a practical solution for multi-generational or growing families.

Rear and Side Extensions

With this, you can open up your living space or kitchen into the outdoor area, while improving natural light and flow.

Modular Extensions

It’s a fast and flexible way to add space without major disruptions. We handle it all—from design to delivery.

Heritage Home Extensions

This is an excellent way of keeping your home’s character intact while making it work for a modern lifestyle. We’re experienced in blending the old and new seamlessly.

From Design to Construction: What to Expect

With us, your project stays in capable hands from day one. We’re more than extension builders; we’re planners, designers, and project managers who make the entire process stress-free. Here’s what you can expect:

Design Consultation

It all starts with a conversation, where we listen to what you need. Our team thoroughly assesses the space and maps out options that suit your lifestyle as well as your budget.

Plans and Permits

Navigating council approvals can be tricky, but you don’t need to worry—we handle it for you. We’ll prepare detailed plans and take care of any permit requirements, sparing you the hassle.

Clear Staging and Agreements

Our process runs in clear stages: design development, preliminary works, and final contract. With proper planning, we keep things simple, transparent and easy to follow.

Construction

Once everything’s approved and agreed upon, we get to work. Additionally, independent surveyors regularly inspect each stage, and you’ll receive a final certificate on completion.
