Hi Master Cecil, Based on your observation, that means for Sky Terrace, blk 89 unit 02 & 04, blk 90 unit 10 & 12, blk 91 unit 18 & 20, blk 92 untit 30 & 32 will be a better choice since the main windows or living room are facing Margaret Drive, which is North facing? Another question, how do we actually select the so-called right unit for everybody in the household? For example, in my current house, you had mentioned one of the rooms were not suitable for sleeping and thus, we use it as a wardrobe. How can we avoid that when we select a HDB flat? Especially a BTO? Regards, Kenny
