Dear Master Cecil, I wish you well. Could you kindly help to differentiate between a period 7 or period 8 house. How does one determine a house as period 7 or period 8? The HDB flat that I am currently living is built in 1989, I moved in 2011, without much renovation, except changing the toilet door, and the toilet seat. Is this still consider as period 7 or a period 8 house? Kindly advise if possible. Thank you very much for your kind advise.; Greatly app
