Start With the Need

More Space Should Improve the Whole Home

A successful extension is not only about adding floor area. It should respond to what the household needs now, how people move through the existing rooms and how the proposed space can support everyday life. That might mean opening the kitchen to a larger living area, adding a quieter bedroom zone, creating a dedicated place to work or strengthening the connection to the backyard.

Plan the Connection

Make the Added Space Part of the Home

Room proportions, circulation, daylight, outlook and furniture placement all influence whether an addition feels useful. Considering these connections early helps define a brief that relates the new area to the rooms and outdoor spaces around it.

Connecting Old and New

The Junction Deserves Careful Planning

The transition between existing and proposed work can affect structure, weatherproofing, floor levels, services, natural light and finishes. Reviewing those interfaces as the scope develops helps make the practical relationship between old and new clear before construction.

Discuss Your Home Extension

Grouped Project Scope

Define the Extension as a Connected Project

The final inclusions depend on the property and agreed scope. Grouping the work around the existing home, approvals, construction and completion helps make those boundaries easier to discuss.

Existing Home and Site

Review the current layout, known structure and services, access, site information and the spaces the household wants to change.

Design and Approvals

Identify the drawings, engineering, consultants, selections and approval coordination relevant to the proposed scope.

Build and Integration

Define the structural, service, weatherproofing and finishing work needed to connect the addition with the existing home.

Completion and Handover

Confirm the final walkthrough, outstanding details and relevant project documentation included in the agreed scope.

An Extension-Specific Process

Work From the Existing Home Outward

An extension process needs to consider both the new work and the home already on the site. The detail of each stage depends on the property and agreed scope.

Prepare for the First Conversation

Bring What You Know About the Home

You do not need a complete drawing set to enquire. A concise picture of the property, the space problem and the intended timing gives the discussion a useful starting point.

Property Details

Share the address or suburb, property type and anything known about the age or construction of the existing home.

Space Priorities

Describe the rooms or connections that need to change and what is not working in the current layout.

Available Information

Include any plans, sketches, surveys, reports, approvals or site photographs already available.

Timing and Wider Work

Note the intended timing and whether bathrooms, outdoor living, a pool or other connected work forms part of the broader vision.

Home Extension FAQs

Are home extension projects available across Brisbane?

BN Total Construction considers home extension projects across Greater Brisbane. Availability depends on the property location, scope, timing and current capacity.

What information should I provide about a home extension?

Do I need completed plans or approvals before making contact?

No. Share whatever information is available about the property, intended space and timing. Existing plans and approvals are useful where available, but the first conversation can also identify the documentation, consultants and approvals that may be relevant to the site and scope.

What affects the scope and cost of an extension?

The existing home, site conditions, structural work, services, documentation, approvals, finishes and the extent of the added space all affect the project scope. These factors are reviewed as the work is defined.

Can a bathroom or outdoor area be included in an extension?

Bathrooms, outdoor living and related work can be considered as part of a connected residential project. Include the wider project vision in your enquiry.
