House Extensions Tauranga

Expand Your Home Without Moving

A well-designed house extension can transform the way you live without the cost and disruption of moving to a new property. Whether you need additional bedrooms, a larger living area, a new master suite, or more space for a growing family, a carefully planned extension can add both functionality and value to your home.

At BCN Studio, we provide architectural design and building consent documentation for house extensions throughout Tauranga, Papamoa, Mount Maunganui, and the wider Bay of Plenty. We work with homeowners, builders, and consultants to develop practical design solutions that integrate seamlessly with existing homes.

Tailored Extension Design

Every home and every client is different. A successful extension is about more than simply adding square metres. It should complement the existing building, improve the flow of the home, and make the best use of the available site.

We take the time to understand how you use your home and identify opportunities to improve both functionality and comfort. Whether you are planning a small bedroom addition, an ensuite extension, a second-storey addition, or a complete living area expansion, we can develop a design that meets your goals and budget.Building Consent Documentation

Most house extensions require Building Consent approval before construction can begin.

BCN Studio prepares detailed Building Consent documentation that helps contractors, engineers, and councils clearly understand the proposed work. Depending on the project, documentation may include:

  • Site plans

  • Existing and proposed floor plans

  • Elevations

  • Building sections

  • Construction details

  • Specification notes

  • Coordination with structural engineers

  • Building Consent application support

Our focus is on producing clear, accurate documentation that assists in achieving a smooth consent process.

Working with Existing Homes

Designing an extension often presents unique challenges that do not exist in a new build. Existing structures, site constraints, council requirements, and unknown construction details all need to be carefully considered during the design process.

We can assist with:

  • Single-storey extensions

  • New bedrooms and ensuite additions

  • Living room extensions

  • Kitchen enlargements

  • Internal alterations and reconfigurations

  • Garage conversions

  • Deck and outdoor living additions

  • Renovation and extension combinations

Where required, we coordinate with surveyors, structural engineers, truss designers, and other consultants to help move the project forward.

A typical extension project may follow these stages:

Initial Consultation

Discussion of your goals, budget, site constraints, and design opportunities.

Concept Design

Development of preliminary plans to establish the preferred layout and overall design direction.

Detailed Design

Refinement of plans and coordination with consultants and engineers where necessary.

Building Consent Documentation
