Feng Shui for landed property & common sense

Before getting that great layout of yours signed-off!

Always superimpose e.g. the ground floor layout onto the second storey and look out for the location of the stove(s) and toilets and vice-versa.

Often, this is to check on whether the 2nd storey toilet is directly above the main door and/or dining table and/or altar and/or bed location on the ground floor etc...
