Add a Second Story to Your Home in Wellington & Kāpiti

THE HIGHEST STANDARDS OF CRAFTSMANSHIP AND INNOVATION IN NEW ZEALAND

When space on your section is limited, building upward can be an effective way to create significant additional living space. A second storey addition allows you to increase the size of your home while keeping your existing outdoor areas.

Second Story Additions

Adding a second story is one of the most effective ways to create more space without increasing your home’s footprint. Whether you need extra bedrooms, bathrooms, or additional living areas, building up allows you to transform how your home works for your family.

At NZ Proud, we specialise in second storey home extensions across Wellington and the Kāpiti Coast. As a local renovation builder, we understand the unique challenges of building up. From steep sites and limited access to structural upgrades and council requirements, we know what it takes to plan and deliver these projects successfully.

With experience across hundreds of homes in the region, NZ Proud provides the expertise to design and build second storey additions that integrate seamlessly with your existing home.

Wellington & Kāpiti Second Storey Specialists

Second storey additions are one of the most complex types of renovation projects and require specialist experience working within existing homes. At NZ Proud, extensions and alterations are at the core of what we do.

Second storey additions require careful coordination between designers, engineers, and builders to ensure the new level integrates properly with the existing structure.

Our second storey addition projects commonly include:

• Additional bedrooms
• Master bedroom suites

Frequently Asked Questions

Do you provide project management?

Open Question Icon

Yes. NZ Proud provides a qualified Project Manager and experienced site Foreman to scope, and manage your project from start to finish.

What financing options does NZ Proud offer?

Open Question Icon

NZ Proud can work with a local mortgage broker who can help advise on your budget and financial plan for any renovation project. It's recommended you discuss your financial position prior to engaging any builder as it's a critical piece of information to provide accurate advice.

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 guide you through the entire process or can collaborate with your own chosen designer.

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 licensed Contracts Manager 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.

Do you offer a guarantee on your work?

Open Question Icon

Absolutely. NZ Proud are members of the Master Builders association and can offer our clients the comprehensive 10 year Master Build guarantee. Our NZ Proud Guarantee includes a low-risk billing process, workmanship warranty, and 10-year implied warranties under the Building Act.

How early should I talk to a builder?

Open Question Icon

It's best to involve a renovation builder early in the planning stage. NZ Proud can provide practical advice and early cost guidance before plans are finalised, helping avoid costly redesigns later.

How much disruption should we expect during renovations?

Open Question Icon

All renovations involve some disruption, but careful planning helps minimise the impact. NZ Proud works with homeowners to plan projects in a way that keeps the home as functional as possible.

What council rules apply to second storey additions?

Open Question Icon

Second storey additions must comply with council planning rules such as height limits, boundary setbacks, and building envelope requirements. Because NZ Proud regularly completes renovation projects across Wellington and Kāpiti, we understand what can and cannot be built on different sites and can guide you through the consent process.

Can we stay in the house during a second storey addition?

Open Question Icon

In some cases yes, but many second storey projects require temporary relocation during key stages. NZ Proud discusses this early so you can plan ahead.

Does my house need strengthening before adding a second storey?

Open Question Icon

Many homes require some structural strengthening before an upper level can be added. NZ Proud works with engineers to assess your home and design the right structural solution.
