Frequently asked questions

Everything you need to know before creating your plan or estimating your renovation budget.

Is Kodarch suitable if I know nothing about building work?
Yes. The interface stays accessible: the calculator speaks in VAT-inclusive ranges and understandable line items, and the editor guides you through creating a room (standard shapes or freehand drawing). You can move forward without construction jargon.
Can two people use Kodarch together (couple, housemates)?
Yes. One account lets you save the project and return to it on mobile or desktop. The plan and estimate become your shared reference before contacting contractors.
Is the budget calculator a formal quote?
No: it's an indicative estimate to frame your project. Firm quotes come from contractors — Kodarch helps you compare them with your initial range.
How do I share my project with a contractor?
From your project, create a share link: the contractor views the plan and can send you a priced proposal. You receive a notification and compare offers on your project's dedicated page.
Can I get started without creating an account?
Yes. You can run the calculator or create a first floor plan without signing up. An account becomes useful for saving, sharing and comparing quotes over time.
