A home project is easier to plan when you can see where the money goes.
Kiwi Projects is a growing collection of tools for New Zealand homeowners. We are starting with heat pumps and decking: what a project may require, what it could cost, and which assumptions deserve a closer check.
Help before you request a quote
Our aim is to help you prepare for a conversation with a tradesperson. You should be able to compare options, understand the assumptions and ask better questions, without handing over your contact details to run a calculation.
What is available today
The heat pump calculator covers single rooms, whole-home scenarios, installation price ranges, running costs and provisional grant scenarios. The decking calculator estimates boards, framing, fixings and an indicative installed budget for common NZ materials.
What the calculators can and cannot do
These tools are planning estimates. They use visible assumptions and broad ranges rather than live supplier quotes or a room-by-room structural design. A qualified installer, builder, engineer or council should confirm the parts of your project that require professional judgement.
We do not claim professional engineering certification, government endorsement or formal sign-off. Read the methodology and editorial policy for the current limits.
