maybe downgrading to HDB - private residential property owners (PPOs) and ex-PPOs are required to serve a wait-out period of 15 months after the disposal of their private properties
my competitor ikea always recommend the ID that you mentioned whenever customers ask for design and installation of kitchen or workspace. Singapore IKEA's corruption ran deep for years. https://www.cpib.gov.sg/cases/pte_bribes-return-food-supply-contracts.html
Thinking of renovation, those malaysian carpenters never complete work on time. Cost is not an issue, if can get approvals to modify structures, modify PUB pipes and chop big old trees, even better.
any good IDs to recommend?
