10 Things to Know Before You Start Your Home Renovation in New Zealand
Home renovation Christchurch Renovating your home can be exciting. Maybe you want a bigger kitchen, a modern bathroom, an extra bedroom, more living space, or simply a home that works best for your family.But if you’re planning a home renovation in Christchurch, there is a lot to think about before the first wall comes down.
How much will it cost?
Do you need a building consent work take?
Should you renovate or move?
And perhaps most importantly, how do you choose the right builder? A good renovation starts with good planning. In this guide, FACL Construction shares 10 important things Christchurch homeowners should know before starting a renovation in 202
1. Start With a Clear Renovation Plan
Before contacting builders, take some time to work out exactly what you want to change.
It is easy to say, “I want to modernise my house.” But a builder needs more detail.
Do you want to:
- Renovate your kitchen?
- Upgrade your bathroom?
- Remove an internal wall?
- Add another bedroom?
- Create a larger living area?
- Add a home office?
- Extend the house?
- Improve indoor-outdoor living?
- Renovate the whole property?
Write down your priorities.
It is also useful to separate your ideas into must-haves and nice-to-haves.
For example, fixing an old bathroom may be essential, while installing premium designer fittings may be something you can decide on later.
Having a clear scope makes it easier to understand the likely cost and helps prevent major changes once construction has started.
Building Performance recommends finalising as much of the project detail as possible before applying for consent because changes later can create additional costs and delays.
2. Set a Realistic Renovation Budget
One of the biggest mistakes homeowners make is starting a renovation without knowing how much they can comfortably spend.
Your budget should include more than just the builder’s labour.
Depending on your project, you may need to allow for:
- Design and architectural services
- Engineering
- Building consent fees
- Materials
- Labour
- Plumbing
- Electrical work
- Flooring
- Painting
- Kitchen or bathroom fittings
- Waste removal
- Site preparation
- Contingency for unexpected work
Renovating an existing house can be less predictable than building a new home because you cannot always see what is behind walls, ceilings and floors before work begins.
Building Performance specifically notes that existing buildings can reveal conditions that were difficult to predict during the planning stage.
For this reason, don’t use your entire budget on the initial wish list. Keep some room for unexpected costs.
3. Understand Christchurch Building Consent Requirements
This is one of the most important things to check before starting your renovation.
Not every renovation requires a building consent.
Some low-risk building work is exempt under Schedule 1 of the Building Act 2004, provided the relevant conditions are met. However, structural alterations, additions and other types of work may require consent.
For example, if your renovation involves changing the structure of your home, adding an extension or carrying out certain plumbing or drainage work, you may need to involve the council and appropriate professionals.
If you’re unsure, don’t guess.
Talk to your builder, designer or the relevant building consent authority before starting work.
Even where building consent is not required, the work still needs to comply with the applicable Building Code requirements.
4. Older Christchurch Homes May Need Extra Attention
Every house is different, especially older homes.
During a renovation, you may discover issues that were not obvious when you first viewed the property.
These could include:
- Old wiring
- Plumbing problems
- Moisture issues
- Poor insulation
- Structural problems
- Damaged framing
- Uneven floors
- Older windows
- Roofing problems
- Previous renovation work that was not completed correctly
This doesn’t mean you should avoid renovating an older Christchurch home.
It simply means you should understand that renovation is different from new construction.
The existing building becomes part of the project, and sometimes the real condition of the house only becomes clear once work begins.
A good renovation plan allows for this possibility rather than assuming everything will go exactly as expected.
5. Think About Energy Efficiency
A renovation is a great opportunity to improve the comfort and efficiency of your home.
Depending on the property and renovation scope, you might consider:
- Better insulation
- Energy-efficient windows
- Improved ventilation
- Efficient heating
- LED lighting
- Better draught control
- Efficient hot-water systems
- Improved natural lighting
You don’t necessarily need to upgrade everything at once.
Instead, think about improvements that make sense alongside the work you’re already doing.
For example, if walls are being opened during a renovation, it may be worth discussing whether insulation or other improvements can be addressed at the same time.
The goal is not simply to make your home look newer. A successful renovation should also make it more comfortable and practical to live in.
6. Decide Whether You Need an Extension
Sometimes the problem isn’t the house itself—it’s the lack of space.
If your family has grown or your lifestyle has changed, an extension may make more sense than moving.
You could consider adding:
- An extra bedroom
- Larger kitchen
- Second living area
- Home office
- Ensuite
- Family room
- Sunroom
- Indoor-outdoor living area
A well-planned extension can give you the space you need while allowing you to stay in a neighbourhood you already like.
However, extensions are more complex than cosmetic renovations. They can involve structural design, foundations, roofing, drainage, planning and building consent requirements.
That’s why an extension should be assessed as a complete project rather than treated as simply adding another room.
7. Choose Materials Based on Your Lifestyle
It is easy to fall in love with expensive materials when looking at renovation ideas online.
But the most expensive option isn’t always the best option for your home.
Think about how your family actually uses the space.
If you have young children, a busy kitchen may need durable and easy-to-clean surfaces.
If you have pets, flooring needs to handle everyday wear.
If you plan to stay in your home for many years, spending more on durable materials may make sense.
The best renovation balances:
Appearance + durability + maintenance + budget.
Your builder can also help you understand where it makes sense to spend more and where a standard product may do the job perfectly well.
8. Choose Your Christchurch Builder Carefully
Choosing a builder is one of the biggest decisions you’ll make during a renovation.
Don’t choose someone based only on the cheapest quote.
Look at:
- Relevant renovation experience
- Previous projects
- Communication
- Contract details
- Qualifications and licensing where applicable
- References
- Insurance and guarantees
- Project management
- Understanding of your renovation goals
For residential building work costing $30,000 or more including GST, New Zealand’s homeowner protections include requirements around written contracts and contractor disclosure information. Building Performance also recommends having a written contract even for smaller projects so everyone understands the work, responsibilities and expectations.
A good builder should be willing to explain the process rather than simply give you a number.
9. Don't Change Everything Halfway Through
Changing your mind during a renovation can be expensive.
For example, you might initially plan to replace kitchen cabinets but later decide you also want to move the kitchen to another part of the house.
That one decision could affect:
- Plumbing
- Electrical work
- Flooring
- Walls
- Structural elements
- Cabinet design
- Consent documentation
- Project scheduling
Some changes are unavoidable, especially when unexpected conditions are discovered.
But unnecessary changes should be avoided wherever possible.
Before construction starts, spend time discussing the layout, materials, fittings and finishes with your builder and design team.
The more decisions you can make early, the smoother the renovation is likely to be
10. Plan for Life During the Renovation
This is something homeowners sometimes forget.
A renovation can affect your daily routine.
If your kitchen is being renovated, where will you prepare meals?
If your bathroom is being rebuilt, do you have another bathroom available?
If several rooms are being renovated at once, can your family comfortably stay in the property?
For larger renovations, it may sometimes be more practical to temporarily move out.
Talk to your builder about the expected construction sequence before work begins.
Ask:
“Which areas of my house will be unavailable, and for how long?”
Understanding this early can make the renovation much less stressful.
How Long Does a Home Renovation in Christchurch Take?
There is no standard renovation timeline.
A small bathroom or cosmetic renovation may take considerably less time than a complete house renovation or extension.
The timeframe can depend on:
- Project size
- Design complexity
- Consent requirements
- Material availability
- Weather
- Site conditions
- Number of trades involved
- Unexpected issues
- Changes made during construction
If your project requires a building consent, you should allow time for the design and consent process before construction begins.
A complete and accurate consent application can help reduce unnecessary delays.
Your builder should be able to give you a realistic construction programme once the scope is properly defined.
Is Renovating Better Than Moving?
For some Christchurch homeowners, renovation makes more sense than buying another property.
Moving can involve:
- Real estate fees
- Legal costs
- Moving expenses
- New mortgage arrangements
- Higher purchase prices
- Stamp duty isn’t applicable in NZ, but there are still transaction costs
- Finding another home in the right location
Renovating allows you to improve the home you already own.
You may already like your street, neighbours, school zone and local area.
However, renovation isn’t always the right answer.
If the required work is extensive and the cost approaches the price difference between your current property and a suitable alternative, moving may deserve consideration.
The right decision depends on your property, budget and long-term plans.
Why Planning Matters So Much in a Christchurch Renovation
A renovation is not simply about making a house look modern.
It is about improving how the house works.
Before starting, ask yourself:
What problem am I trying to solve?
Maybe your kitchen is too small.
Maybe your family needs another bedroom.
Maybe your bathroom is outdated.
Maybe your living area doesn’t connect well with your garden.
Once you understand the problem, it becomes easier to decide which renovation work is actually worthwhile.
This approach can also help keep your budget under control.
