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. |
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.
