Single Storey Extensions To Enhance Your Living by Expert Builders and Designers

We build a single storey extension that answer one question: how do you dream of living? Let Extensions Unlimited unlock your home’s true potential with a stunning ground floor extension. We’re not just building bigger homes; we’re building bigger lives.

Our first floor extensions go beyond practicality, creating spaces that integrate with your existing structure, preserving character and your family’s memories. Picture movie nights in a spacious family room flooded with natural light, quiet mornings in a luxurious ensuite retreat, or vibrant gatherings in an expansive entertainment space – the possibilities are endless.

As one of Melbourne’s most experienced home extension builders, our in-house design team works closely with you, crafting functional layouts that maximise space and value, all within your budget. No need for costly external architects – we do it all!

When adding a second storey to your home is not desired or an option, simply extending or adding a room (or two) to your ground floor can be the perfect solution.

A first floor addition is a useful option to increase shared living spaces for growing families or multi-generational living arrangements, add a dedicated home office, or totally rearrange your floor plan to maximise entertaining to get the most out of your backyard. Our in house design team consults on your specific needs to provide single floor extension plans that harmonise with your existing dwelling, that enhance your life through moments life is made of.

Extensions Unlimited has been creating extra space for Melbourne families for over 30 years!

DESIGN SERVICE Free initial meeting with your house extension designer. Tell us about your dream home so we can provide customised and informed solutions.

BUILDING PERMITS AND PLANS Permits are essential before building can begin. We’ll get approval and take care of any fees for you, communicating directly with the council.

CONTRACTS Work is carried out in three stages to minimise disruption: Design Development, Preliminary Works Agreement, Final Contract.

CONSTRUCTION Our constructions are regularly inspected by independent surveyors who issue reports during the progress, with a final certificate upon completion.

What can affect the cost of any extension on your property are factors like property access, the presence of trees (either on your property or adjacent neighbours), the condition of the soil, and the slope of the land, which can affect the ease of excavation.

An expert house extension company like Extensions Unlimited is a great choice for your first floor extension because our communication is impeccable, so there is no surprise extra costs during construction.
