Below: the named roles in your project, where your files live, what the AI is and is not allowed to do, our refund commitments, and the sign-off chain that ends with you handing a signed package to your municipality.
Three named roles. Each owns one part of the chain. No silent hand-offs.
+ responsibilitiesReads your brief; produces a first-pass concept with room areas, code-compliance preview against the local building code (Bbl / ДБН / WT / GEG), and an indicative cost band. Flags every cost and regulation number as indicative.
− limitsDoes not sign anything. Does not carry professional liability. Does not replace site visits, structural calculation, or municipal consultation. Cannot certify a permit.
+ responsibilitiesA named engineer reviews the AI draft against your brief, fixes scope mismatches, and validates the JSON-Schema output. Confirms that the layout is buildable and that the indicative numbers are plausible for your plot.
− limitsNot a registered architect. Cannot sign a Tier 2 permit package. Cannot stamp drawings for submission.
+ responsibilitiesVerifies the package against the local register's standards (SBA / НААУ / IARP / Architektenkammer), refines what is needed, and applies the signed-and-stamped sign-off you submit to the municipality. Carries the professional liability and insurance for that signature.
− limitsSigns only what they have personally verified. Does not certify structural Eurocode calculations (those stay with a Constructeur / structural engineer). Does not supervise the build site.
Where your files live, who can open them, and how long we keep them.
Concrete limits on what the AI can do — implemented in code, not as a promise.
What we owe you, per tier, if the deliverable does not match the engagement.
| Tier 0 (free working draft) | Free. No card on file. No refund needed because no money is taken. If you don't like the draft, simply don't continue. |
|---|---|
| Tier 1 (engineer review) | If the engineer review uncovers a scope mismatch that we did not catch up-front, you get a full refund within 14 days. EU consumers also keep the standard 14-day right of withdrawal under consumer law. |
| Tier 2 (architect sign-off) | If the signed package fails permit submission for a fixable reason within 30 days of delivery, we revise and re-sign the package at no extra cost — or refund the architect-sign-off fee. Refunds do not apply to changes you make to the brief after sign-off. |
One-page editorial reference per jurisdiction (NL, UA, PL, DE). Drawings, calculations, supporting documents, typical fees and the reasons offices reject. One click, no email gate.
Editorial reference. The legally binding answer for your project comes from your municipality and a registered architect signing your final submission.
End-to-end accountability — every link is a named human role until the document is in your hands.
Your brief → AI working draft (within 1 business day).
Working draft → in-house engineer review (typically 3 business days).
Engineer-reviewed draft → registered architect verification and sign-off (typically 2 business days).
Architect-signed package → handed to you, with the architect's register entry and signature visible on the document.
You submit the package to your municipality (Bouw- en Woningtoezicht / місцева влада / urząd gminy / Bauamt).
Tier 0 is free, no card needed. You can read the full AI disclosure first.
