Frequently asked questions
Everything you need to know before creating your plan or estimating your renovation budget.
Does Kodarch replace an architect or surveyor?
No. Kodarch helps visualize and estimate a renovation project: indicative plans, areas and budget ranges. For construction documents, compliance or permits, consult a qualified professional.
Can I use Kodarch without creating an account?
Yes. You can create a first plan or launch the budget calculator without signing up. An account lets you save your projects and access them on mobile and desktop.
How do I import an existing plan (PDF or photo)?
In the editor, import your PDF or image file, calibrate the scale using a known dimension, then rework walls and rooms on top. Ideal for starting from a rental plan or listing.
Is the renovation budget calculator a quote?
No: it's an indicative estimate (total cost range) based on area, finish level and selected items. It helps frame a project before requesting formal quotes from tradespeople.
Can I share my plan with a tradesperson or client?
Yes. Export a PDF technical file with the plan, areas and dimensions to send by email or show on-site. Measurements remain indicative until validated by a professional.
Does Kodarch work on smartphones?
Yes. The interface is designed for on-site surveys on a smartphone, then finishing at the office on a larger screen, with automatic saving of your project.
