Ian & Fiona’s Onehunga ground-floor extension
Renovating in Onehunga

Renovating in Onehunga means making the home you love work for the chapter you’re in.

Onehunga is one of Auckland’s most diverse suburbs — Edwardian bungalows around the older streets, postwar weatherboard family homes, mid-century bungalows, and modern infill near the harbour. The owners are equally varied: empty-nesters wanting to age in place, young families settling in close to the train and motorways, and downsizers from larger central-Auckland homes. We’ve renovated across all of them. Ground-floor extensions, kitchen open-plans, bathroom rebuilds, age-in-place master suites — Ian & Fiona’s retirement-ready ground-floor extension is one of many we’ve delivered in Onehunga.

Our Onehunga Services

We renovate Onehunga homes across three core services.

We renovate Onehunga homes across three core services: kitchens, bathrooms, and full home renovations or ground-floor extensions. Each one is QS-priced before contract, built by our own team, and backed by the Master Builder 10-Year Guarantee. Pick the service that matches your plan — or book a consultation and we’ll help you work out which one.

Kitchen Renovations

Onehunga kitchens are usually the heart of the renovation here. We open up the closed-off layouts, redesign for indoor-outdoor flow, and build joinery to last. Fiona’s dream kitchen in Onehunga — custom cabinets, modern appliances, ample counter space — is the kind of kitchen we’re known for.

Recent Onehunga Project

Retirement-ready, without leaving the home: Ian & Fiona’s Onehunga ground-floor extension.

Ian & Fiona had raised their family in their Onehunga home for over a decade. As they planned for retirement, they wanted to age in place ‘ — a ground-floor master suite to skip the stairs, and Fiona’s dream kitchen for everyday cooking and entertaining.

ServiceGround Floor Extension
AddedMaster suite + kitchen
OutcomeAge in place

Working to a tight budget, we delivered a fully QS-priced 21-section scope, handled the council consent and CCC, and built a ground-floor extension with a master bedroom, ensuite, and walk-in wardrobe ‘ — all level access, all retirement-ready. We rebuilt the kitchen to Fiona’s brief: custom cabinets, modern appliances, and ample counter space. The extension blends into the original home so it doesn’t feel like an add-on. The result: a home that suits today, scales for tomorrow, and adds market value if they ever decide to sell.

Renovation FAQs for Onehunga Homeowners

Below are the questions Onehunga homeowners ask us most often about renovating in this part of Auckland.

What does a ground-floor extension cost in Onehunga?
A ground-floor extension in Onehunga typically costs $4,500–$8,000 per square metre in 2026. For a 30–60m² extension that adds a master suite or extends the kitchen-living, that’s usually $150,000–$450,000 fully built including consents and finishes. Ian & Fiona’s Onehunga ground-floor extension added a master suite with ensuite and walk-in wardrobe plus a new kitchen. AVR provides a fixed-price QS Report before any contract—every cost locked in.
Can I add a ground-floor master suite for ageing in place in Onehunga?
Yes — adding a ground-floor master suite is one of the most common renovations in Onehunga, especially for empty-nesters and downsizers wanting to age in place without leaving the home. Typical scope: master bedroom, ensuite, walk-in wardrobe, often paired with a new kitchen or open-plan living. Ian & Fiona’s Onehunga project is a real example. AVR designs every age-in-place renovation around level access, wider doorways, and stepless showers.
How long does a renovation take in Onehunga?
Most Onehunga renovations take 10–22 weeks on site. A bathroom is 4–6 weeks, a kitchen 6–10 weeks, a ground-floor extension or full home renovation 14–22 weeks. Add 6–10 weeks before that for design, QS pricing, and Auckland Council building consent.
Do I need consent to extend my Onehunga home?
Yes — any extension to the footprint of an Onehunga home requires Auckland Council building consent. Onehunga sits across Mixed Housing Suburban and Mixed Housing Urban zones, with some heritage and character overlays around the older streets near Onehunga Mall and the Princes Street corridor. AVR runs a Council pre-application check before the QS Report so you know exactly what consents apply.
Are renovations in Onehunga covered by the Master Builder Guarantee?
Yes — every AVR renovation in Onehunga is backed by the Registered Master Builders 10-Year Guarantee, which covers structural defects, weathertightness, and workmanship. We’re also covered by $2 million public liability insurance and full LBP certification.
Can I live in my Onehunga home during the renovation?
For ground-floor extensions where the existing home stays intact, yes — the new build happens outside the original walls, and we only break through near the end. For kitchen-only or bathroom-only renovations, we set up a temporary kitchen and contain the work zone. For full home renovations, most Onehunga homeowners choose to move out for 8–14 weeks. We’ll talk through both options at the consultation.
What style of homes does AVR renovate in Onehunga?
Onehunga has a real mix of housing stock — Edwardian villas and bungalows around the older streets, 1950s state houses, postwar weatherboard family homes, and infill townhouses near the harbour. AVR has renovated across all of them: heritage-respectful villa updates, ground-floor extensions on bungalows, age-in-place renovations on family homes, and full home transformations. We know what each style can and can’t support structurally.
Who is the best renovation builder in Onehunga?
Add Value Renovations is a Newmarket-based Registered Master Builder who has completed ground-floor extensions, age-in-place renovations, and full home renovations across Onehunga. AVR was awarded House of the Year Gold (2025), holds a 4.8-star Google rating across 34 reviews, prices every project through a QS-led 21-section scope before contract, and backs every renovation with the Master Builder 10-Year Guarantee plus $2M public liability insurance. Free 30-minute consultation: 09 393 5658.
Will an age-in-place renovation add value to my Onehunga home?
Yes — age-in-place renovations in Onehunga consistently return 1.4–1.7× the renovation cost at resale, and they significantly broaden the buyer pool: families, downsizers, and multi-generational households all value level access, ground-floor master suites, and modern wet-area design. Ian & Fiona’s project is a real example.
What renovation gives the best ROI in Onehunga?
On an Onehunga home in 2026, the highest-ROI renovations are: (1) a ground-floor master suite with ensuite — returns 1.5–1.8× cost; (2) opening up the kitchen-living-dining for indoor-outdoor flow — returns 1.5–1.8×; (3) modernising a tired 1980s bathroom — returns 1.3–1.6×. Onehunga is increasingly desirable for downsizers and young families, so renovations that improve liveability for both groups consistently lift resale.
How does the renovation process actually work with AVR?
Three steps. (1) Free 30-minute on-site consultation — we visit your Onehunga home, listen to what you need, give a rough cost band. (2) QS Report ($500+GST) — our QS prices the full scope across 21 sections so you have a fixed price before any contract. (3) Build — one project manager, weekly updates, council consent handled, delivered on time and on budget under the Master Builder 10-Year Guarantee. Ian & Fiona went through this exact process.

We loved working with Simon and the team at Add Value Renovations. Add Value's project manager Tim, and interior designer Joanna, had excellent communication throughout the entire process. The quality of the workmanship was top-notch and they completed our bungalow renovation on time and on budget.

Just wanted to take a moment to express my appreciation for the outstanding work you've done! A ext. renovation done by Add Value was truly a remarkable transformation. The kitchen and bathroom designs are not only aesthetically stunning but also highly functional. It's evident that a lot of thought and care went into every detail.
