Why Consider a Home Extension Rather Than Moving?
Stay in the Community You Love
The Bay of Plenty is filled with unique neighborhoods that become part of your family's identity. An extension lets you remain in your established community while gaining the space you need.
Significant Cost Savings
When you factor in real estate fees, legal costs, moving expenses, and stamp duty, extending your current home is often substantially more cost-effective than relocating.
Minimize Disruption
A well-managed extension causes far less upheaval than selling, buying, and moving — especially for families with children settled in local schools.
Customized to Your Needs
Unlike buying an existing home with its own compromises, an extension can be precisely tailored to your family's specific requirements and lifestyle preferences.
Increase Property Value
A professionally designed and constructed extension significantly increases your property's market value, often delivering return on investment beyond the actual construction costs.

FAQs
Frequently Asked Questions About Home Extensions
How much does a typical home extension cost in Tauranga?+
Extension costs vary significantly based on size, complexity, materials, and site conditions. As a general guide, quality extensions in the Bay of Plenty typically range from $3,000–$5,000 per square meter for single-story extensions and $5,000–$7,000 per square meter for second-story additions. During our initial consultation, we provide a more accurate estimate based on your specific project requirements.
How long does a home extension project take to complete?+
Timelines vary by scope and complexity. Typically: small to medium extensions (single room) take 2-3 months, larger extensions (multiple rooms) take 3-5 months, and second-story additions take 4-6 months. These timeframes include the building consent process, which typically takes 4-6 weeks.
Can we live in our home during the extension construction?+
In most cases, yes. We implement strategies to minimize disruption including temporary barriers between living areas and construction zones, maintaining essential services, and coordinating noisy work around your schedule where possible. We discuss practicalities during our planning phase.
Will our extension match the existing house?+
Absolutely. Creating seamless integration between new and existing structures is our specialty. We carefully match materials, finishes, proportions, and architectural details to ensure your extension looks like it was always part of the original home.
What council permits are needed for home extensions in Tauranga?+
Most substantial extensions require building consent from your local council. Depending on your property's zoning and the extension's size, you may also need resource consent. As part of our service, we manage the entire consent process with Tauranga City Council and other Bay of Plenty councils.
How do you handle site access and neighbors during construction?+
We implement considerate construction practices including clear communication with neighbors before construction begins, strict adherence to permitted working hours, careful management of deliveries and site traffic, and regular site cleanup to minimize impact on your community.
