Home Extension Builders Melbourne

ROMAAC Group delivers major home extensions across Melbourne and throughout Victoria, with licensed building capability in Queensland. From ground-floor additions and expanded living areas to second-storey extensions, we coordinate planning, structural work, services, construction and finishes so the new space works naturally with the existing home.

Why Extend Your Existing Home?

A well-planned extension can give you the extra space you need without leaving a home or neighbourhood that already works for you. The right design can improve layout, comfort and functionality while creating a stronger connection between the existing house and the new areas.

Why Choose ROMAAC for Your Home Extension?

Major extensions require careful coordination between the existing structure, new design, engineering, permits, trades and finishes. ROMAAC manages those elements across projects in Victoria and Queensland, with a focus on build quality, practical delivery and clear communication.

Check
Existing & New Construction Coordination

ROMAAC coordinates structural junctions, floor levels, roofing, services and finishes so the new work connects effectively with the existing building.

Tailored Extension Planning

Each extension is approached around the existing home, site constraints and the way you want to use the additional space rather than applying a standard layout.

Detailed Construction & Finishes

Attention is given to the transition between old and new construction, along with joinery, flooring, stone, lighting and other finishes that influence how cohesive the completed extension feels.

Planning, Permits & Project Coordination

ROMAAC coordinates the construction program, permits, consultants, trades, suppliers and inspections required to move the extension from planning through to completion.

Clear Communication Throughout

Clients are kept informed about project progress, key decisions, selections and issues that require attention throughout the build.
