Quick questions

Where do code answers come from?

From the building codes and standards currently in force where you build; every answer cites the document number and clause so you can check the original.

Are there learning materials on the web?

Yes. The knowledge base explains terms, the 24 Mountains, house facing and building codes in three languages; every page has a Markdown version for citation.

Can lecturers use it in class?

Yes. Present plans, the compass and the analysis straight from the app, or export PDFs to hand out to the class.

What does “scientific feng shui” mean at Home Check?

Feng shui expressed through measurements and positions: orientation calculated in degrees, faults pinned to the exact room and item on the plan, wind and sun computed at the exact site — so anyone can verify it.
