Proper Job

ChatGPTby SR3H LTD

Estimate building and renovation costs from what you know, then refine the price with size, location, scope and readable plans. Uses country-specific benchmarks in local currency for supported work in the United Kingdom, United States, Australia, New Zealand, Ireland, Germany, France, Spain, Canada, Japan and India. Available work types vary by country. Unsupported work is identified rather than priced as if supported. Compare Budget, Standard, Premium and Luxury in the interactive card. Use metric or imperial measurements; Japanese inputs also support tatami and tsubo. See the price breakdown and add optional details without starting again. When you attach readable drawings in ChatGPT, ChatGPT reads them and Proper Job calculates from the extracted quantities and scope. The calculator does not use a paid Proper Job drawing-extraction service or access your saved Proper Job jobs. ChatGPT account and attachment limits still apply. Prices are budget estimates, not quotes or professional advice. Check the stated assumptions, exclusions and applicable local requirements before committing to work.
