Dear Sherwin,yes I wish to calculate the FSnatal chart,n is the chart a permanent for the particular building? But I still need to make this clear,how do we judge where is the facing of the building?The building have four sides r all with apts' balcony facing outward n only 1 main entrance ,so do we consider the main entrance of the building is the facing? We bought an apt recently in Melb. for our son,n his Gua is 8,what if we have no choice of choosing the best bedroom?Cos the b/rooms r at the East of the apt. n the bedrooms' doors r facing more to South n SE?Hope u can help! Regards,Lilian

Hi Lilian, a Flying Star chart may change with massive renovation to the entire building. Take the 'intended facing' of the building. Soon, you will learn about 'House Gua' and then you will be able to tell, based on the facing/sitting, which sectors in the property are good to use.Cheers! - Sherwin.
