No Offence, but for this sort of price and typical link house, dont even expect clay brick, if they give, then you are damn lucky....a lot of superlink, semi-D, and also those selling more than 1mil also contructed with sand brick.....

Secondly, it was rightly pointed out that the partition wall normally done up with clay brick....but i wasnt surprise if they use sand brick nowadays, developer is finding ways to cost cost or increase profit.....

Technically yes but practically , there are many ways to do so (to set up G&G with individual title house), i am referring to new development. However, there are pros and cons:

1. All buyers are not committed to pay as when they purchased the house, they didnt expect this
2. Not easy to function well and can only have certain aspect of a full G&G that include the landscape, the more proper fencing, optional CCTV, etc.
3. ease of implementing certain policy and enforcement .
