House Extensions in Auckland – Get the Home of Your Dreams Without Moving

Do you want to change or add to your house to make it more suitable to the way you live? Whether you need more space for a growing family, you want to add new features to your house, or for any other reason, building an extension is an excellent choice.

As we have significant experience completing house extensions in Auckland, we can help with every stage of your project. You can call on our expertise for advice whenever you need it, and we’ll make the building experience as smooth and hassle-free as possible. This includes discussing options for how the build will impact you, particularly if you plan to live in the house while the work is ongoing.

Pre-Construction Stage

Developing a design for your extension and then planning the construction work are the key elements in this phase.

At Bos Construction, we can help further develop a plan or idea you already have, or we can provide input on what is possible to help you achieve what you want to achieve.

We have excellent knowledge of building regulation requirements and the requirements of the Council, and we can help with appointing an architect, engineer, or any other professional required on your extension building project.

Our team will also look after planning the construction work, including creating the schedule and ensuring the project is properly costed to keep it within your budget.


Once all the plans are approved and you are ready to go, we’ll begin work on site. Each builder on our team and all the sub-contractors that we use are qualified, certified, and experienced. Everyone working on your extension will also be fully committed to delivering the high-quality standards that we demand on every project.

We’ll communicate with you regularly throughout this part of the project, and we’ll be professional and reliable. Quality is built into all our processes, and we work safely. We’ll stand over our workmanship, too, providing you with a guarantee.

Once the building work is complete, we will do a walkthrough to make sure you are completely happy. All that will be left for you to do will be to enjoy your newly extended home.
