Will house renovation affect CLT Geomancy Grid?

It depends. Minor work like redoing the floor or part of the ceiling which does not involve the house structure will not affect. But when it is structural, such as tearing down wall or altering the interior layout, caution must be exercised. The renovation may block energy pathway, invoke negative energy where there was none before or create missing corners; which all undermine one’s total well-being, in terms of wealth, career, health, relationships, etc.
