RenovationStart is built by one person: Ritchel Akwali, also the maker of VerbouwStart.nl, the independent Dutch renovation cost calculator. This is the English sister: same engine, same rule. Honest numbers with sources, tools that work without an account, and nobody buying your details behind the page.
Renovation cost information is dominated by sites that exist to sell your contact details to builders. The numbers on such sites have a job, and that job is not accuracy. This site does the opposite: the price comes first, with its source and its assumptions, and your details are not part of the business. The method is public on how we price, and what little is counted, anonymously, is listed in the privacy page.
Mail info@verbouwstart.nl (the shared inbox with the Dutch mother site; I read it daily). Corrections, questions and partnership ideas all welcome; if you found a number that looks wrong, include the page and I will check it against the source.
One product, priced openly: the Renovation Pack (one-off, no subscription) with five AI quote checks, after your first free one each month. I sell no leads, no commissions from builders, no advertising space, and never your data. Everything else on the site is free, because it costs me nothing per use; the AI checks do cost real money per run, and that is exactly what the pack pays for.
Because you can check them. Every range comes from named 2026 cost guides, carries its assumptions, and the calculator, the cost pages and the planners all draw from the same validated data, so they can never disagree. The full method is on how we price.
Please do. One person cannot see everything, and the honest-numbers promise only works if errors get fixed fast. Mail me and include the page; corrections go live quickly.
