I fully understand Mr Tan Khoon Hui's desire to cash out (Selling Pine Grove would help older residents financially; Dec 17).

I have another perspective on collective sales.

While we are promoting a green environment, we are unnecessarily destroying buildings which may still be useful when we sell them en bloc.

Should we not evaluate if a building is still in liveable condition before subjecting it to destruction?

Or are we implying that our buildings are not built to last?

For those concerned about income inequality, perhaps a flat collective sale tax could be imposed on those who reap significant profits, tax free, from the sale.
