How much does it cost to renovate a bungalow in Auckland?

A full renovation on a typical 140–190m² Auckland bungalow runs $280,000 to $445,000. Premium and architectural work with a significant addition runs $480,000 to $695,000. A cosmetic refresh, where the bones are already sound, starts around $165,000. After your design phase we give you a fixed price, so you know exactly what you're investing before any work begins.

Is renovating a bungalow cheaper than a villa?

Slightly, sometimes, but not reliably. Bungalows often sit on concrete footings or concrete piles rather than timber in the ground, so you frequently save on re-piling. You tend to spend that saving on asbestos management, relining brittle lath and plaster, and the structural work needed to open up the rear for light. Budget the same 25 to 40% character premium over an equivalent modern house.

Does my bungalow have asbestos?

Possibly, and it's the main thing that separates a bungalow from a villa. Later bungalows and almost any alteration done between the 1950s and 1970s can contain it — in soffits, textured ceilings, vinyl and its backing, and some claddings and roofing. We flag anything suspicious at the Roadmap stage and arrange a survey before demolition begins, never after.

Why is my bungalow so dark, and can it be fixed?

A 2.7 metre stud, deep verandahs shading the front rooms and smaller casement windows. It is absolutely fixable, but it's a structural and planning decision rather than a lighting one — opening the rear, raising or removing a ceiling, glazing to the north and borrowing light through the plan. Fix that first and everything else you spend looks better.

Should I keep the rimu?

Almost always. Floors, skirtings, architraves, picture rails and box beams are usually heart rimu, often hiding under carpet or paint. It restores beautifully and you can't buy it any more. We check for borer and soundness, then strip or sand and finish it.

Can I replace the casement windows with aluminium?

You can, and we'd advise against it. Casements and leadlights are most of what makes a bungalow read as a bungalow, and they're repairable — new stays, reputtying, releading a bowed panel. If you're in a Special Character Area, changing street-facing windows may also need resource consent.

Do I need to re-pile a bungalow?

Less often than a villa. Many bungalows were built on concrete perimeter footings or concrete piles, which have generally held up. But plenty still have timber, and some have had a bad 1970s patch job underneath. We get under the floor before anyone prices anything.

Do I need resource consent to renovate a bungalow?

Many bungalow suburbs — Mt Eden, Sandringham, Epsom, Kingsland, Devonport and others — sit inside Special Character Areas under the Auckland Unitary Plan. Broadly, changes to the street-facing form need resource consent, while work behind the original building line has more freedom. Structural, plumbing and drainage work needs building consent wherever it is. Rules vary by overlay and by property, so check yours early. We run the process for you.

How long does a bungalow renovation take?

Six to ten weeks of design, four to twelve weeks of consent, then four to eight months on site for a whole-house renovation. Longer with a significant addition.

Where in Auckland do you renovate bungalows?

Right across the character belt — Mt Eden, Sandringham, Balmoral, Epsom, Mt Albert, Kingsland, Onehunga, Point Chevalier, Devonport and Northcote Point — plus the wider central, eastern and North Shore suburbs.

How long does a home renovation take with Key Interiors?

Timelines vary with scope. A kitchen or bathroom renovation typically takes 3-6 weeks, while a complete home renovation can span 8-12 weeks, with every detail managed professionally for a seamless result.

Do I need council consent for my renovation?

Only for structural or plumbing changes. Key Interiors will help you navigate all necessary approvals if required.

Can I live in the home during the renovation?

Yes, in many cases. Key Interiors works to minimise disruption, and your dedicated project manager keeps you updated throughout.

Do you provide fixed quotes?

Yes. After your design phase, we provide a transparent fixed-price quote with a clear scope, materials and timeline before any building begins.

What does a renovation cost in Auckland?

As a guide: bathroom renovations from $25,000, kitchen renovations from $35,000, and complete home renovations from $150,000. We work with your budget to deliver the best value.

What We Do

Our Villa & Bungalow Renovation Services in Auckland

Every older home has different requirements. Some need an updated kitchen and bathroom, while others need a complete renovation, structural work or an extension. Key Interiors provides design, construction, custom joinery and project management to bring everything together.

Full Villa & Bungalow Renovations

When several rooms need attention, renovating the whole house can create a more consistent result.

We plan the improvements together, from updating old layouts and wall linings to coordinating kitchens, bathrooms, flooring, lighting, insulation and interior finishes.

Where necessary, we also arrange appropriate structural and building-services upgrades.

The result is a home that feels connected from room to room, without losing the features that make it special.

Kitchen Renovations for Character Homes

Older villas and bungalows often have kitchens tucked away at the back of the house, with limited bench space and little connection to the dining or living areas.

We design kitchens around the way you cook, store things and spend time with family.

Depending on your home, that might mean opening up the kitchen, adding an island, improving storage or creating custom cabinetry that fits neatly around original walls and detailing.

Our kitchen renovation services include design, joinery, installation and finishing.

Villa & Bungalow Bathroom Renovations

A beautiful bathroom still needs to work properly behind the tiles.

Older homes may have uneven floors, limited ventilation, ageing plumbing or timber structures that need extra care before the bathroom is rebuilt.

We consider the condition of the existing space, waterproofing requirements, storage and layout before choosing finishes.

Whether you're updating a family bathroom, adding an ensuite or creating a more spacious shower, our bathroom renovation services are planned to suit both your home and your daily routine.

Open-Plan Living & Home Extensions

You don't always need a bigger house. Sometimes you need to make better use of the space you already have.

Removing or changing selected internal walls can improve the way the kitchen, dining, and living areas connect. Better window placement, natural light and access to the garden can also change how a home feels.

Where more room is needed, we can help plan rear extensions or other additions that work with the original building.

Structural changes and extensions are considered alongside any relevant council consent requirements.

Custom Joinery & Interior Design

Standard cabinetry doesn't always fit an older house, especially where walls are uneven, ceilings are high or original detailing needs to be retained.

We design custom joinery to suit the available space, including kitchen cabinets, wardrobes, bathroom vanities, laundry storage and built-in shelving.

Our interior design services bring together the materials, colours, lighting, and finishes so that new additions feel comfortable alongside the home's original character.

Restoration & Structural Improvements

Before investing in new finishes, it's important to understand the condition of the existing house.

Depending on the property, renovation work may involve repairing timber, addressing subfloor moisture, upgrading electrical or plumbing systems, replacing unsuitable wall linings or improving insulation and ventilation.

We identify areas that need further investigation early and coordinate the appropriate specialists where required.

Character Comparison

Villas and Bungalows Need Different Thinking

They look like cousins, but they go wrong in different places. A villa usually fights you from underneath. A bungalow usually fights you for daylight.

"A villa usually fights you from underneath. A bungalow usually fights you for daylight."

AUCKLAND CHARACTER VILLA

The Victorian & Edwardian Villa

Villa Renovations: What's Under the Surface

Auckland villas have the high ceilings, sash windows, timber floors and plasterwork people pay a premium for. A hundred-odd years on, they also tend to come with:

Tired foundations. Piles that have sunk or rotted, and a subfloor with little or no ventilation.

Scrim and sarking. Hessian and boards behind the wall linings, which have to be removed before the walls can be properly insulated.

Old services. Wiring and plumbing that are well past their best.

Nothing quite square. Sloping floors and out-of-plumb openings, so cabinetry has to be scribed to fit.

We keep what makes it a villa: the timber floors, sash windows, cornices and street presence. The kitchen someone added in the 1970s doesn't count as heritage.

AUCKLAND CRAFTSMAN BUNGALOW

The 1920s & 30s Bungalow

Bungalow Renovations: It's Mostly About Light

Bungalows often have better bones than villas. They also have lower ceilings, smaller windows, deep verandahs and rooms that feel dark by mid-afternoon. The rimu floors, casement windows and leadlights are worth keeping. The floor plan usually isn't. So the work tends to centre on:

Light. Rear glazing, roof lights and a layout that lets daylight travel further into the house.

Open living. Connecting the kitchen, dining and living areas, and the garden beyond them.

Asbestos. Surveyed before demolition starts, particularly in later alterations.

Casements and leadlights. Repaired rather than swapped for aluminium.

Get the light right first. The kitchen looks better for it, too.

Step 3 – Construction & Renovation

Once the design, scope and pricing are approved, construction begins.

We coordinate the relevant trades and manage the work, including structural alterations, building services, wall linings, cabinetry and interior finishes.

Step 4 – Finishing & Handover

We aim to leave you with a home that feels considered, comfortable and ready for everyday living.

Frequently Asked Questions About Villa & Bungalow Renovations

How much does it cost to renovate a villa in Auckland?

The cost depends on the size, existing condition and scope of work. Key Interiors' indicative budget for a full character home renovation is $280,000–$445,000, while major renovations and extensions can cost more. A site assessment and a design plan are needed to prepare an accurate price estimate.

What is the difference between renovating a villa and a bungalow?

Villas often require attention to older foundations, high ceilings, sash windows and traditional wall linings. Bungalows can have different framing, lower ceilings, casement windows and darker living areas. Both require careful planning to protect original features while improving modern comfort.

Can I modernise my villa without losing its character?

Yes. You can retain the original timber floors, decorative ceilings, windows, and other suitable period details while updating the kitchen, bathrooms, lighting, storage, and layout. A well-planned renovation allows old and new features to work together.

Can you create an open-plan layout in a bungalow?

In many cases, yes. Removing or modifying internal walls can improve the connection between the kitchen, dining and living areas. A structural assessment is required where load-bearing walls are involved, and consent may be needed.

Do I need council consent for a villa or bungalow renovation?

It depends on the work and the property's planning controls. Structural alterations, extensions and certain plumbing changes may require building consent. Resource consent may also apply, particularly where heritage or special character provisions affect the property. We help review the requirements during planning.

How long does a villa or bungalow renovation take?

A full home renovation may take approximately four to eight months of construction, depending on its complexity. Design, documentation and council approvals can add time before the build starts. We discuss the expected programme once the scope is clearer.

Can I stay in my home during the renovation?

It depends on the extent of the work. You may be able to remain at home during a smaller or staged renovation. For major renovations involving the kitchen, bathrooms, electrical services or large sections of the interior, temporary accommodation is often more practical.

Do you renovate original timber floors and character windows?

Where the existing materials are in suitable condition, we consider retaining and restoring timber floors, skirtings, decorative joinery and original windows. The appropriate approach depends on their condition and the overall renovation design.

Can you renovate only the kitchen or bathroom in my villa?

Yes. Key Interiors undertakes individual kitchen, bathroom and laundry renovations as well as complete home renovations. We assess the space and surrounding construction to help ensure the new work fits the existing home.
