Suresh’s Mt Roskill second-storey extension
Renovating in Mt Roskill

Renovating in Mt Roskill means unlocking more space without leaving the suburb you love.

Mt Roskill is one of Auckland’s most established family suburbs — postwar weatherboard homes, 1960s brick-and-tile bungalows, and an increasing number of two-storey rebuilds across May Road, Carr Road, and around Mt Roskill Grammar zone. The original homes here are well-built but tight on space. Second-storey extensions, footprint extensions, full home renovations, and rooftop entertaining decks are exactly the work we do here. Suresh’s second-storey extension — which doubled the floor area and added a Louvretec rooftop deck — is one of many we’ve delivered in Mt Roskill.

Our Mt Roskill Services

We renovate Mt Roskill homes across three core services.

We renovate Mt Roskill homes across three core services: kitchens, bathrooms, and full home renovations or 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

Mt Roskill kitchens we build open up the closed-off 1960s layout into a modern open-plan kitchen-living-dining — the centrepiece of the home. We’ve done this on multiple Mt Roskill bungalows, and the lift in liveability and resale is consistent.

Why Mt Roskill Chooses AVR

Mt Roskill homeowners choose AVR for extensions and renovations that work for the next decade.

Four reasons Mt Roskill families keep choosing us — and keep sending their friends.

200+ Auckland renovations completed since 2010

QS-led pricing — every cost upfront.

We price every Mt Roskill renovation through a 21-section QS scope before contract. What you sign is what you pay — every cost transparent and locked in from the start.

Master Builder 10-Year Guarantee.

Every AVR renovation is backed by the Registered Master Builders 10-Year Guarantee. Structural, weathertightness, workmanship — covered for a decade. Plus $2M public liability insurance.

We know Mt Roskill homes.

Postwar weatherboard homes, 1960s brick-and-tile bungalows, and 70s family homes on flat 600–900m² sections — that’s the housing stock here. We know what the existing framing and slabs can carry, where the easy structural wins are, and how to extend up rather than out.

Second-storey extension specialists.

Going up rather than out is the highest-leverage move on most Mt Roskill homes. Engineering, council consent, structural strengthening, and the build itself ‘ — all handled under one contract. Suresh’s family doubled their floor area without leaving the suburb — one of many second-storey extensions we’ve delivered here.

Backed by our Master Builder 10-Year Guarantee.

Recent Mt Roskill Project

Doubling the floor area without moving: Suresh’s Mt Roskill second-storey extension.

Suresh’s family had outgrown their Mt Roskill home as the grandkids started visiting. Instead of moving, we doubled the floor area with a second-storey extension and added a Louvretec rooftop deck for year-round outdoor living.

Service2nd Storey Extension
AddedRooftop deck + carport
FeatureLouvretec roof

Suresh wanted entertainment space for visiting grandchildren without moving out of Mt Roskill. Other builders had given vastly different quotes with little detail on the structural work. We delivered a fully QS-priced 21-section scope, ran the engineer’s feasibility study, handled the council consent, and built the second storey with a rooftop deck, Louvretec opening roof, glass balustrade, bifold aluminium doors, and a new carport on the ground level. The result: double the floor area, year-round outdoor living, and a home that grows with the family.

Renovation FAQs for Mt Roskill Homeowners

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

What does a second-storey extension cost in Mt Roskill?
A second-storey extension in Mt Roskill typically costs $4,800–$8,200 per square metre in 2026. For a 60–100m² upper floor add-on, that’s usually $300,000–$700,000 fully built including engineering, council consents, and finishes. Suresh’s Mt Roskill project doubled the floor area with a rooftop deck and Louvretec opening roof. AVR provides a fixed-price QS Report before any contract—every cost locked in.
Can my Mt Roskill home support a second storey?
Most 1950s–1980s Mt Roskill homes (the dominant housing stock here) can carry a second-storey extension with the right structural design. Older brick-veneer and weatherboard-on-timber-frame homes usually need foundation strengthening and reinforced wall framing, but it’s rarely a deal-breaker. AVR runs an engineer’s feasibility assessment as part of the QS Report so you know the structural cost upfront before committing.
How long does a second-storey extension take in Mt Roskill?
A second-storey extension in Mt Roskill typically takes 16–26 weeks on site, plus 6–10 weeks before that for design, engineering, QS pricing, and Auckland Council building consent. Smaller deck-and-room additions land closer to 14 weeks; full second floors with multiple bedrooms and bathrooms run 20–26 weeks.
Do I need consent for a second-storey extension in Mt Roskill?
Yes — second-storey extensions always require Auckland Council building consent and usually engineering certification. Mt Roskill is mostly under the Mixed Housing Suburban or Mixed Housing Urban zone, which generally allows two storeys, but height-to-boundary, recession plane, and site coverage rules still apply. AVR handles the consent application, drawings, and council liaison end-to-end.
Are Mt Roskill renovations covered by the Master Builder Guarantee?
Yes — every AVR renovation in Mt Roskill 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 Mt Roskill home during a second-storey extension?
Yes, in most cases. A second-storey extension is largely separated from the existing ground floor during the build—we open the roof, lift the new floor in, and only break through to the existing ceiling near the end. Many Mt Roskill families stay in the home, with a few weeks of disruption while the new staircase is connected. We’ll talk through it at the consultation.
What is a Louvretec roof and is it worth it in Mt Roskill?
A Louvretec opening roof is a powered louvre system that lets you control sun, shade, and rain over an outdoor entertaining space. In Mt Roskill’s mixed Auckland weather, it turns a deck into a year-round outdoor room. Suresh’s Mt Roskill rooftop deck uses a Louvretec roof above the BBQ and dining zone—rain or shine, the family can use it. AVR specifies and installs the Louvretec system as part of the build.
Who is the best renovation builder in Mt Roskill?
Add Value Renovations is a Newmarket-based Registered Master Builder who has completed second-storey extensions, full home renovations, and bathroom and kitchen rebuilds across Mt Roskill and central Auckland. 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 a second-storey extension add value to a Mt Roskill home?
Yes — second-storey extensions in Mt Roskill consistently add 1.4–1.8× the renovation cost in resale value, especially when they create additional bedrooms, a master suite, or a multi-generational living configuration. Mt Roskill is a strong family-buyer suburb close to Auckland’s arterial routes and Mt Roskill Grammar zone, so adding floor area without extending the footprint is one of the highest-leverage moves you can make.
Can I add a rooftop deck or outdoor entertaining area in Mt Roskill?
Yes — rooftop decks and outdoor entertaining areas are increasingly common in Mt Roskill, particularly above carports and garages. They require structural design (weight loading, drainage, waterproofing), building consent, and usually a balustrade. Suresh’s Mt Roskill project added a rooftop deck above a new carport with a Louvretec roof, glass balustrade, and bifold doors connecting it to the upper-level living area.
How does the renovation process actually work with AVR?
Three steps. (1) Free 30-minute on-site consultation — we visit your Mt Roskill 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. Suresh’s family went through this exact process.

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.
