Each yes = 1 point out of 15. Groups: site/architecture, envelope, services/autonomy — five questions each. This checks preparation completeness, not certification or building quality.

Project self-check
Transparent assumptions and a preliminary result.
This checks preparation, not the building
The self-check helps identify whether basic information is assembled for a design discussion. A tick records your answer; it does not automatically verify a document. Fifteen positive answers cannot establish safety, compliance or low energy use. The useful outcome is a distinction between topics with identifiable evidence and topics that still require clarification.
Answer against actual information
Before ticking an item, locate the drawing, calculation or agreed decision. If information exists only in conversation or an old revision, leave the question open until checked. A partial answer should not conceal the main uncertainty: owning a ventilation unit does not mean routes and commissioning are resolved. Note who is expected to supply missing information so that the checklist leads to an actionable discussion.
Use the total as an agenda
The tool counts selected items and groups; it does not assign engineering importance to each question. One critical omission can matter more than several completed secondary items. Save the result with the current project revision and use it to structure a conversation with the team. The 37-question checklist offers broader preparation; a design audit addresses the drawings themselves. A PDF records your answers but does not turn them into a professional opinion or a graded assessment of the proposed house.
