Construction cost estimator
The cost estimator gives an indicative cost for building or renovating, based on the project details you enter.
It is a planning aid: the output is an estimate to help you budget, not a quotation from any business.
Describe your project
Choose a project type — or add a custom project type of your own — and enter the details of what you plan to build or renovate.
Get an indicative breakdown
The estimator returns an indicative cost with a breakdown, so you can see roughly where the money goes before you speak to contractors.
Take it further
From an estimate you can post a requirement, collect quotations from verified businesses, and compare real prices against your plan.
