Just like any other project, the developer will try put a lot attractive pics to attract the buyers' interests of the views of what they will be expecting but of course it not always the prefect case, every month they will sure to be new project building and there always a risk that good view might be blocked.
People had different view and judgement, especially for unfinished project is harder to imagery how the view will be, therefore you will need to trust your decision and judgement of what will be the view that u will be expecting to see from now. From what my view that bedroom no.2 & 3 which is facing more to south, the window will be about to view a bit of the city and taking reference from earlier comment from one of the member is that 8RS and concourse residence had completed it will for sure block the view of the flyers and MBS therefore leaving a small view of the city when you are looking from far.
Another if you are buying a higher floor unit, U will be expecting a nice stanning view as well, I rem there is a project The Mezzo someone posted picture of the view facing TTSH and Novena area in the forum.
Therefore is important what you believe and see.
