Why Extend

A well-planned extension should feel like it always belonged

Add the space you actually need

Extensions let you add bedrooms, living space, or a larger kitchen-dining area without giving up a location that already works for your family.

Stay in the home you already value

If the block, street, school catchment, or neighbourhood already suits you, extending can be more practical than starting over elsewhere.

Use your site more intelligently

A well-planned extension can improve flow, orientation, light, and connection to outdoor areas while respecting the existing house.

Handle structure and integration properly

Good extension work is about more than adding area. The new and existing parts of the home need to connect properly in structure, services, and finish.

What We Handle

What’s included in a quality home extension

The best extension outcomes come from treating the project as a full building exercise, not only an extra room attached to the side of the house.

Ground-floor home extension with indoor outdoor living

Ground-floor room additions

Add living areas, bedrooms, kitchen-dining zones, or alfresco connections with a layout that improves the way the home works.

Gold Coast home with a second-storey addition

Second-storey additions

Expand upward where the site or brief suits it, with careful attention to structure, stairs, roof form, and how the addition integrates with the existing house.

Structural framing for a home extension project

Structural and footing works

Manage the practical construction side properly, including demolition, structural framing, steel, roof changes, and the building work needed to support the extension.

Seamless connection between an existing home and a new extension

Connection to the existing home

Make the transition between old and new feel natural in flow, levels, openings, materials, and finishes rather than obviously added on.

Home extension planning, samples, and approvals preparation

Approvals and build-ready planning

Work with the required consultants and approvals process so the extension is planned realistically before site work begins.

Builder-led coordination materials for a home extension

Builder-led project coordination

A clear process for pricing, staging, scheduling, site management, and handover backed by licensed construction oversight.

Shane Newnham — Director, Newnham Constructions
“When someone trusts you with their home, that's not something we take lightly. We build every project like our name is on it - because it is. From the first conversation to handover, I want every client to feel like they're working with people who care deeply about getting it right.”

Extension Project Feedback

What clients say about the finished result

The extension feels like it was always part of the house. The new living area connects beautifully and the build quality is excellent.

Michael R.Ashmore

We needed more room without moving. Newnham handled the planning and construction in a calm, organised way and the result feels seamless.

Tara & Ben S.Robina

The second-storey addition changed how the house works for our family. Communication was clear and the finished spaces feel considered and solid.

Common Questions

Home extension FAQs

Costs vary depending on the size of the extension, structure, approvals, and the level of finish required. We provide a detailed quote once we understand the scope and inspect the property properly.
Many extension projects do require approval, particularly when the footprint, height, structure, or setbacks are changing. We help clients understand what is required and how to move through that process properly.
Yes. We handle both ground-floor extensions and second-storey additions, with attention to structure, stairs, roof form, and how the new work integrates with the existing home.
Often yes, although it depends on where the extension is located and how disruptive the structural work will be. We discuss staging and practicality before site work starts.
Many extension projects take about three to eight months on site, depending on approvals, complexity, structure, and finishes.
No. The right project depends on the site, the existing home, and the outcome you want to achieve. We look for projects where builder-led planning and quality construction matter.
Yes. We hold QBCC Open Builder Licence #20668 and are Master Builders Queensland members (#02048).
