Some people slope the roof into the Brahmasthan and take the water down through a central pipe. Does that affect the house?
Yes, it is wrong. Even if the floors slope to the North-East, a roof whose whole slope falls into the Brahmasthan creates the same defect as a slope toward the centre.

For a plot of, say, 33 x 70 that is not fully built, do we take the whole plot or only the constructed part?
Take the constructed area. For the boundary wall gate the centre of the whole plot is used, and for the main door the centre of the constructed area; this is taught in planning.
How do we find the centre of a plot that is irregular or stretched on one side, since the demonstration used a regular plot?
Finding the centre was covered in earlier classes. Either use software such as AutoCAD, or use the hanging method: cut out the shape, hang it from one point and mark the vertical line, then hang it from another point and mark again; the crossing is the centre. Joining diagonals gives the centre only for a regular plot.
If the Brahmasthan is kept open on the ground floor, should the same area be kept open on every upper floor?
Keeping it open on all floors is excellent. If that is not possible, a double height open at the Brahmasthan, for example about 20 ft, still balances the space element even if it is closed above. A survey found that houses with a double height at the Brahmasthan had more happiness and peace.
In Dubai most flats have toilets in the Brahmasthan padas; how can this be treated?
The Brahmasthan's energy reaches every part of the house, so a toilet there affects everything. Nullify it with the mercury injection method all around, leaving the Brahma bindu itself untouched.
In the house I am moving to, my room may fall in the Brahmasthan or the North-East. Which is right during pregnancy and delivery?
Do not stay in the Brahmasthan at any cost; sleeping in the drawing room, or even on the road, would be better. If zoning the whole area puts the room in the North-East, it can be used with discretion, but it is not ideal; the best zone for a delivery is the South-West, the zone of stability. A backyard on the North side is good.
Is it fine if a dining chair comes over the Brahmasthan?
Keeping the Brahmasthan empty is best. A brahma nabhi can be made, but the Brahma bindu itself must always be kept empty.
