Im one of the sales agent mutiara hilltop, the front door will not facing opposite unit you may refer the photo as below.

If tower A&C you can refer the layout plan no 5 and 6 the main door will face to opposite unit becase this 2 unit is mirror reflection design, and why devoloper will launch the price so affortable because the price shown on ADPL is the approved pricing by government, means government actually allow the developer to sell at this pricing, its valued at this price range. if its not because of this bad market, developer wouldn't launch so cheap honestly 😅 since the phase 1 selling 70% with 3 months so phase 2, block C definitely price will be higher, developer will increase the pricing then.

Actually during this saturday 830pm devoloper have a project briefing by zoom if anyone interested can pm me.

Its ok, im not sure which part of my answer let you feeling im missleading you, all the answer is just based on the information provide from devoloper.
