Questions

Straight answers to the questions we hear most often on the tools and over the table.

Contact
Do you handle the consent process?

Yes. We can assist from the early planning stages, whether you already have your own architect or need help connecting with trusted professionals. We work closely with architects, surveyors, and engineers to ensure your project is well planned before construction begins. 

What areas do you cover?

Based in Auckland, we work with clients across the North Island, from the Far North to the Waikato and beyond. Whether it’s a city site, lifestyle block, or rural property, we bring the same level of care, organisation, and quality to every project.

How do you price a build?

We provide clear, detailed pricing based on your plans, selections, and the scope of work. We believe in transparency from the beginning, with changes clearly communicated and agreed before moving forward.

What is your timeline like?

We create realistic programmes from the outset and keep you informed throughout the build. While factors like weather and supply delays can occur, we communicate early, plan proactively, and work efficiently to keep your project moving towards completion.
