Welcome to Rag Reno's: Crafting Memories, Not Just Homes

At Rag Reno's, our ethos is simple: we believe that the process of building and renovating should be as remarkable as the end result.

Founded with a clear vision, we set out to transform the often-intimidating world of construction into a journey filled with excitement and positivity. Whether you're a valued client, a dedicated subcontractor, or a member of our passionate team, our commitment is to make this experience memorable and stress-free.

John, our founder, hails from a lineage of builders. From early days working alongside family members to honing his craft in London's upscale renovation scene, John's extensive hands-on experience in the industry is both diverse and rich.

However, it was his return to New Zealand in 2011 that marked the inception of Rag Reno's. Initially a modest little company, we started with the support of his parents and have since flourished. Today, it stands as a testament to years of dedication, with John at the helm alongside his wife, Sarah.

Our approach is rooted in authenticity and integrity. From small renovations in our early days to more expansive projects now, our promise remains unchanged: genuine assistance, transparent pricing, and an unwavering focus on quality.

Communication

We value transparent communication to keep you informed throughout your journey with us. You will have access to our project management software giving you real-time progress on site and any decisions that need to be made. We will also have a weekly onsite meeting to go over the work in progress.

People

We are a family owned and operated business. We bring our personal approach and family values to the build. We will personally guide and help you through the building process from design to completion.

Guarantee

Being a member of the master builders association of New Zealand means we can offer our clients a 10-year master builder guarantee as well as our own Rag Reno’s Guarantee.

Fixed Price Contract

We provide our clients with a fixed price quote. This means there will be no changes in price unless you change your mind. What we price is what you pay.

Trustworthiness

Gaining and keeping trust with our clients is important to us. Our friendly team work alongside a reliable and trustworthy team of subcontractors and suppliers. We can assure you we know the people that are working on your home at all times.

Safety

Site safety is our priority. We partner with Hazardco and use their systems to ensure our sites are run and operated in a safe manner. We are committed to looking after the safety of all those involved in the project including you as the owner.

We're proud of the homes we build and renovate. Whether we're updating an older house or building a new family home, we focus on craftsmanship, clear communication, and a result that suits the property and the way your family lives.

Auckland Renovations

Renovation Builders for Auckland Homes

Renovating an existing home takes more than good workmanship. It requires a builder who can understand the way your family lives now, uncover what is happening behind the walls, and plan a practical path from the home you have to the home you want. Rag Reno’s provides renovation services across Auckland, helping homeowners improve character houses, family homes, and properties that need more space, better flow, or a full modernisation.

Our work is centred on clear planning, straightforward communication and construction that respects the original home. Some clients come to us with architectural drawings ready to price. Others only know that their kitchen is too small, the bedrooms no longer work, or an older villa needs careful attention. We meet you at that starting point, explain the likely options and help turn the brief into a buildable scope.

Home renovation services shaped around your property

Every renovation is different, so the right service depends on the condition of the house and what you want to achieve. Rag Reno’s works on full home renovations, internal reconfigurations, kitchen and living-area upgrades, additions, extensions and structural alterations. We also help with projects that combine several needs, such as opening the main living zone, improving indoor-outdoor connection, adding a bedroom and upgrading ageing services at the same time.

For a smaller project, the priority may be making existing rooms warmer, lighter and easier to use. For a larger renovation, the work can include structural changes, new foundations, roofing, windows, insulation, plumbing, electrical upgrades, bathrooms, kitchens and detailed finishing. Bringing those parts together under one construction plan helps reduce gaps between trades and gives you a clearer view of the real scope before work starts.

If you are comparing an addition with a complete rebuild, we can help you look at the practical trade-offs. The existing structure, site access, soil conditions, consent requirements, intended finish level and the amount of new floor area all affect the answer. Our Auckland home addition cost guide explains the main 2026 pricing drivers and the allowances homeowners should discuss early.

Serving Auckland from our Franklin base

We build and renovate across the Auckland region. Local knowledge matters because ground conditions, site access, the age of the housing stock, and council requirements can change significantly from one property to the next.

Auckland homes range from rural properties and lifestyle blocks to established town houses, post-war bungalows, and early timber villas. A renovation that suits a newer subdivision may not be right for a character home with original framing, uneven floors, or previous alterations. We assess the property in context so the proposed work fits both the building and the way you want to use it.

Villa and bungalow renovation specialists

Villas and bungalows have character that is difficult to reproduce, but renovating them well calls for careful decisions. Original weatherboards, timber floors, sash windows, decorative details and traditional room proportions may be worth retaining, while old wiring, plumbing, insulation and foundations often need upgrading. The goal is not to make every old home look new. It is to preserve the features that give the house its identity while making it warm, safe and practical for modern family life.

We begin by identifying what should stay, what can be repaired and what needs to change. That may mean opening the rear of a villa for a kitchen and living area while keeping the front rooms intact, improving the connection to a deck or garden, or adding space in a way that does not overwhelm the original form. In bungalows, the opportunity is often better circulation, more natural light and a clearer relationship between living spaces. Our 2026 Auckland villa renovation cost guide outlines the price ranges and hidden conditions to allow for.

How We Work

A clear renovation process from first conversation to handover

A successful renovation is easier when everyone understands the next decision. Our process is designed to make scope, cost, responsibilities and timing visible from the beginning.

  1. Step 01

    Initial consultation

    We discuss your goals, the problems you want to solve, your preferred timing and the investment range you are considering. This first conversation helps establish whether renovation, extension or another approach best fits the brief.

  2. Step 02

    Site assessment

    We review the existing home, access and visible construction conditions. For character homes, we pay particular attention to previous alterations, floor levels, moisture, foundations and the likely age of services.

  3. Step 03

    Design and scope development

    We work with your plans or help coordinate the design pathway needed to define the project. The scope is developed far enough to price the real work, not only the obvious finishes.

  4. Step 04

    Pricing and programme

    You receive a clear proposal that explains what is included. Selections, allowances and any exclusions are discussed before construction so they do not become avoidable surprises later.

  5. Step 05

    Construction and communication

    Once work begins, we coordinate trades, site safety and quality checks. Clients receive project updates and have regular opportunities to review progress, decisions and upcoming stages.

  6. Step 06

    Completion and handover

    We inspect the finished work, resolve agreed completion items and walk you through the renovated home. Warranty information and the relevant project documentation are provided as part of handover.

Local Experience

Why local experience matters during a renovation

Renovation work is rarely identical to the drawings once the existing structure is opened. The difference between a manageable discovery and an expensive delay is often preparation. A locally experienced team knows to investigate the common risks, set sensible contingencies and keep decisions moving when hidden conditions appear.

Rag Reno’s is a family-owned building company and a Registered Master Builders member. We use established subcontractors and suppliers, provide progress visibility through project-management software, and hold regular site conversations so clients are not left guessing. Our fixed-price approach is based on the agreed scope; if you choose to change that scope, the effect is explained before the variation proceeds.
