Where to look?

As you know, Auckland is well known for its property and location, there is a lot of room available for renovation particularly in the older regions such as Ponsonby, Mt Eden, Sandringham, Glenfield, Howick etc. Almost in every area of Auckland, there are house renovations happening. The critical role to renovate a property if you’re looking to see is to increase its perceived value and equity in the market to attract the right buyers at your target selling price, which isn’t easy considering the demographics in every suburb is different.

Subdividing also seems to be quite popular in recent years and this is due to the large land available for older homes.

2. How much does it cost to renovate in Auckland in 2021?

Confirming the renovation costs is a bit tricky and complicated

It depends on requirements and ideas of the client and the range can be quite large. If you’re considering on buying a place to renovate, try to get a ball park figure for the renovation to avoid not having enough budget after the purchase. If you’re renovating for your own home, focus on the necessities first and then the wants later if the budget allows.

There are some renovation costs/rates that can be calculated in advance if you know the size of the area you want done (but keep in mind this would be an average). You should have a 10% contingency budget should you start any renovation, there are also unforeseen costs once a renovation starts – perhaps you want to get extra things, or there was rotton timber that needs replacing.

3. Cost of home extensions Auckland

Why consider a house extension when you could sell your Auckland house and move to a larger home? Here are four good reasons to consider adding a house extension:

  • If you like the area you’re living in, you don’t have to move
  • Make the changes you want to make and not settle for something that’s just okay
  • A home extension may be more affordable than moving to a larger home
  • You may be attached to your current home or location and not want to leave

As a general rule of thumb, the average cost of a house extension in Auckland – a 50SQM ground floor house extension costs $100,000 – $150,000. That works out to $2,000m2 – $3,000m2. The difference is in the type of construction and the quality of the inclusions.

You won’t know the exact cost of a home extension until you’ve made plans and know how large the extension is going to be and what will be included in the extension. The cost of Architectural plans will go from $3,000 – $5,000 dependant on complexity.

Cost of Two storey House Extensions in Auckland

What about two-story extensions?

If both storeys are the same size, a generally-accepted rule is to add 50% extra to the build cost of a single storey house extension.

$150,000 + 50% = $225,000

Add 20% for professional fees and GST (15%).

Don’t forget about windows, finishings and fixtures when you’re pricing your house extension, Make sure you include these in your planning and cost estimates. If you don’t, you could be in for a surprise when the final invoice comes.

Planning a house extension is a big job that can seem daunting, especially with so many things to think about. It’s best to start with figuring out the cost. Once you’ve got a rough idea of how much your extension will cost, you can move forward with everything else.

There are other places to start, of course. But the best place to start will always be with a general cost calculation.

Double Glazing Cost per square metre (NZ)

Retrofitting double glazing costs, a lot lesser than getting entirely new double glazing with new frames. You can expect to pay about $15,000 to $18,000 for a 100m2 home. An insulated glass unit and drainage system is installed in your current window frames. While this is a cheaper option, it is not possible to install the insulated glass unit in your current frames for most homes in Auckland.

It is only possible for new homes where the window frames are in great condition. Older home in Auckland do not have frames that are in good condition as they are often damaged or skewed. If you have a newly built home with single glazing, then opt for retrofitting your double glazing as it is a more cost effective option with similar insulation levels as new double glazing with new frames.

Is a home renovation worth it?

People are confused if renovating their property will increase its value or not. Let us assure you that if you are a resident of Auckland, then renovation is the best way to increase your property’s value and beauty.

This is the reason that the knowledge regarding Home renovation Auckland is very essential. The best way to pursue is that you should overestimate the budget for renovation and set the sale priceless. This will let you make a proper price and profit analysis.

Whether you intend to modernise an old kitchen or enhance your outdoor space by adding a deck to your home, your first step when planning a renovation will be figuring out the cost, work and time involved in the project.

6. So here are a few tips to help you get off to a good start for your house renovations.

  • Do you research, figure out what you want

You should have a clear idea of what you want before you start getting quotes and choosing materials. If you know you want to redo your bathroom, but aren’t sure what style you want, you can get inspiration from home improvement and design magazines or use Pinterest to find creative ideas and bookmark them for later.

  • Make a detailed plan

Creating a detailed renovation plan is essential to the success of your renovation project, and while your renovation company can certainly help with this, there are some things you’ll need to decide on beforehand, including your budget and preferred materials and finishes.

  • Allow plenty of time for your renovation

Home Renovation projects in Auckland can often end up taking a lot longer than anticipated, so you should allow plenty of time for unexpected delays. Planning in more time than you think you’ll need to prevent unnecessary stress when things move more slowly than anticipated.

  • Make sure you have considered all your options

It’s best to get advice and proposals from a few different renovation companies in Auckland before making a final decision so you can compare them and make sure you are making an informed decision. Of course, high-quality materials cost more and skilled contractors often charge more than less experienced ones, so check the contractor’s reputation, ask plenty of questions and look for hidden fees.

The key to renovating your Auckland Home beautifully yet inexpensively is to devise a goal for yourself, and paint an entire picture of what you want and then step by step renovate each part of your house with the guide of a trusted renovation company – they’ll be able to guide you through the process by giving you sound advice to avoid costly mistakes.


7. What should I look for when choosing a renovation company?

Don’t get distracted by flashy websites, and nicely designed vehicles –   the right renovation company only needs to have experience, resources, organizational skills and a genuine interest in helping you renovate your dream home, see below on what you should look for.

Here are the top 5 things Aucklanders should be looking for in a potential renovator:

  1. An impressive portfolio of past projects –  Check for case studies and details of the renovation (specifications) and ask a lot of questions. Another reason why you want to choose a company with an impressive portfolio of past projects is that a company that has done a lot of renovations, would have also been through a lot lessons/mistakes along the way that you can avoid.
  2. A proven track record with projects of similar scale and detail  – Make sure you choose company that has done work that is similiar if not the same as what you’re looking for. The mistake most people make is choosing a company that does everything, but an expert in nothing.
  3. Great communication -- Clues are in their online reviews (unsolicited) and video testimonials (if any, not all companies have this and it’s not easy to get raving clients). Ask for details of past clients who are happy to be called and interview them, if a company can’t provide you a list of at least 5 – there may be red flags.
  4. Excellent organisational skills –  This may be a bit difficult to judge, but it’s in the details such as:
    1. What was their sales process like? was it systemised?
    2. How was their follow up and their initiative?
    3. How well did the booking go with the office team?
    4. Was there a clear indication of next steps?
    5. How accurate was their proposal based on your requirements?
  5. Great real customer testimonials, and not from their website: Google them, visit other pages besides their website,  and check out their Facebook reviews/posts ( are there any negative comments?)
  6. Make sure they are affiliated with reputable suppliers: Make sure you know where they are getting their supply from to ensure you’re getting good quality fittings installed, and you’re also backed by independent product warranties.


8. Renovation Cost Calculators

Due to popular requests for ball park figures, which is a fair request for those who are considering renovating or are just researching – we’ve put together 3 cost calculators (built in-house) to help.

Frequently Asked Questions

Will I have a choice of fixtures and fittings and can I supply them myself?

Absolutely – if you would like to purchase anything directly and provide it for installation at the appropriate time then we have no objections to this but we always suggest clients to choose our suppliers for a number of reasons, we’re confident of the quality, we can manage the logistics, trade prices, and any troubleshooting during the renovation is easier since we can direct contact.

Do I need to employ any other trades for the renovation?

Generally an established renovation company will have all their trades setup and a network of suppliers they use and trust. It just makes the renovation a lot less stressful and cost-effective. A house renovation will typically require 8 – 10 different trades and if any of which are unreliable they will affect all other trades involved. For this reason we are reluctant to carry out a renovation if a customer wishes to employ trades separately.

All the builders I’ve spoken to say they can do my Job. What makes Superior Renovations different?

Yes, there are many builders out there today, but Superior Renovations are not just builders. We specialise in Home Renovations, and that is important when transforming existing properties into modern contemporary homes – our service isn’t limited to renovation but we also take care of the design process, consultation process with architects, consents and supplier communication/logistics.

Once this is received, then you know what you need to consider – check lists are very helpful to simply the process otherwise it does become overwhelming.

Do I need a building consent for my renovation?

If you are carrying out building work you may need to apply for a building consent. Here are some examples of work that requires consent: Any structural building including new buildings, additions, alterations, accessory buildings (sheds), and re-piling Changes to original plumbing and drainage Site works for a building Retaining walls higher than 1.5 metres, or retaining walls with a building or driveway near the top Fences higher than 2.5 metres and any swimming pool fence Swimming pools Decks more than 1.5 metres from ground level If in doubt we recommend you ring your local council and discuss your project with them.
