Sweeten, a consumer-to-contractor matching service, wanted to chart the landscape of residential renovations as far back as we could find. We took the NYC Department of Buildings database, scraped it and built a solid database using a combination of open-source tools. In the end, we gave them an explorable map of 10 years of residential changes.
