Frequently Asked Questions

How do I start the renovation process?

Open Question Icon

Make sure you start by selecting the right builder. Credibility, experience and service is crucial from the start and throughout your renovation journey.

Your first consultation with NZ Proud is carried out by a qualified and experienced builder whose primary goal is to gather information and give you advice on your vision so you have the right information to make informed decisions. You can get started by contacting us here, and answer all the prompted questions as best you can, and we'll book a site visit at the earliest convenience.

What should I consider when planning a home alteration or extension?

Open Question Icon

Early planning is key to a successful project. Before speaking with a builder or designer, think about the outcome you want to achieve, are you looking to create more space, improve how your home functions, or modernise key areas through a larger upgrade? Consider what’s driving the project, whether it’s a growing family, working from home, or an existing layout no longer meeting your needs. Budget is just as important, not just what you think the build might cost, but what you’re comfortable investing. Speaking with your bank or broker early will help define what’s possible. With a clear vision and budget, your builder or designer can provide more accurate advice and guide you through options such as extensions, layout reconfigurations, garage conversions, or exterior upgrades like cladding and windows. Here is some more information on home extensions.

How much does a home extension cost in the wider Wellington region?

Open Question Icon

The cost of a house extension varies depending on the size, complexity, and materials. We'd love to be able to give an idea straight away, however, this comes down to many factors, with the most important one being what your budget is.

Do you offer design services, or do I need to hire an architect first?

Open Question Icon

We partner with experienced architectural designers and manage the design process for you. You don’t need to engage an architect separately — we offer a full design-and-build service. You can find out more here.

Do I need building consent for a renovation in Wellington or Kapiti?

Open Question Icon

Yes — in most cases, you'll need building consent for structural renovations, bathroom relocations, or any work involving plumbing, drainage, or structural changes. Some smaller projects such as kitchen and bathroom renovations, may not require a building consent if the renovation is a simple upgrade of what's existing. NZ Proud can provide information to help you make an informative decision in relation to the need for building consent. Our qualified and liscensed builders have a wealth of experience in compliance requirements when renovating existing properties. You can find out more about council consent here.
