Year-by-year cost plan built from 23 house components with sourced lifespan ranges and per-country cost data (Finland, the Netherlands, Sweden). Fair-price check for contractor quotes by trade, VAT-inclusive. Mandate writer: a written brief committing the contractor to scope and a price ceiling before work starts. Repair-or-replace calculator based on component age and degradation. Component passport: your house's components, ages, and history in one place. The methodology is public and free — guides, glossary, calculators, no signup. No engagement mechanics; designed to be barely opened. Zero third-party requests; analytics is first-party and cookieless. €37/year.

You own a house and a contractor's quote lands: you check it against the fair range for that trade and job size, then send back a written mandate that caps scope and price before work starts. You want to know what the coming years will cost: the year-by-year plan shows what comes due when — roof, boiler, windows — and what to set aside monthly. Something breaks: the fix flow triages how urgent it is and what happens if you wait. You're weighing repair against replacement on an ageing component: the calculator answers from the component's age and lifespan, not a guess. The guides, glossary, and calculators are free with no signup; the app is for running your own house on the professionals' operating model.
