You can get a quote (or an estimate – which can change afterwards) from a builder, the global cost including materials but if you want to understand how much are the general material cost, there are some ways to know it.
- Building materials
Bunnings, Mitre10 and Placemakers are the largest do-it-yourself factory shops in New Zealand. It is the most popular shops where builders use with ”builder’s discount”. These builders are sometimes invited to special trade events (e.g. fishing, trip to Australia, etc) and they sometimes favour one particular distributor and get some margins as profit.
If you have time, you can also check the global cost by yourselves. You can create your own “builder” account (cash or credit) to get the same or smaller discount if you are planning to get a big renovation done. You can call the sales representatives and they are happy to visit your house for estimating the total cost of the renovation. This will be a good idea (if you are doing a big renovation to understand the cost of materials). I have done this and it was useful 1) to get discount for my painting materials which I have done ourselves and 2) to compare the cost shown by the builder for a negotiation.
If you are intimidated to ask them to come over, you can just bring your architectural drawings (with materials indicated) to the trade shop and they will give you back the total estimated cost of materials in a couple of weeks.
They may not have the detailed price of kitchen or bathroom materials but they can indicate a general cost of beams, nails, necessary glues, insulations, deck materials – in great details.
2. Kitchen – joiner costs
If you have a design by the architect, or your own idea already, you can ask the architect (not recommended as it often is not true and would go over) or a couple of joiners by bringing your idea or discussion to get a quote or an estimate.
I now understand that a normal size of kitchen could vary from 20K to 50K or even more depends of materials (bench top, appliances) in New Zealand.
Most of the drawer materials or appliances are imported and thus expensive, so the more you have a drawer, you may add 800-1000 dollar depends on how you open the drawer. I personally imported a few materials from Europe and this was not relatively more expensive than to make it in New Zealand – as the labour cost is expensive here – and I could finally get a quality design kitchen with European appliances. I can indicate a few contacts who are specialised in this area.
3. Bathroom – tiles and bathtubs
Chinese tiles vs Italian tiles. All the tiles are imported here. If you tile your bathroom, especially the shower area, you need a building consent. In 1994 – 2004, New Zealand had a leaky home crisis. Which means that they are extremely careful and strict about the wet-area renovation. You need a good tiler for application. Well, you can do tiling yourself (but not recommended), as you need a qualified tiler to make a certificate to the council. Often, the tiler has a specific store (to get a discount) for a tile and give some recommendations.
For a bathtub, toilets, etc. Mico, Plumbing world, ZIP are the major specialised stores. Knowing what to choose as a brand is also a key to compare the prices and its quality. I have chosen material based on my experiences in Japan and in Europe which are imported here. So I cannot comment much about the materials made in New Zealand.
