I have drawn a layout of my house (landed property)and also have the sitting and facing directions. However, I am unsure of how to draw the grids in order to find the nine sectors. Supposing a house is square shaped, we would take the length and width of the house and divide by 3. This would give us equal sized grids/sectors. What happens if the house is rectangular? Do we use the same method? This would mean that the grids would be long and narrow.

My house is in need of roof repairs (to repair a major leak)and ant-treatment. This year, the Grand Duke is residing in the Nortwest and the Three Killing is in the North sector. These are the areas where the repairs are needed. If both these jobs are urgently required (and they are) is there anything I can do to avoid any problems or should I postpone the roof repair and carry on with the ant-treatment. The drilling required for ant-treatment will be causing alot of noise in these areas anyway. Please advise.

Many thanks!! Scf

you can expand the 9 palaces if the house is rectangular, or you can use pie chart. you can hold the renovations for the time being.
