and they want to do that because???

everyone seems to forget that developers are for profit organisations...

Everything they do.. every landscape they create... they don't do it for nothing...
Most projects with massive landscaping are being built as part of the selling/marketing point to the other properties that they are selling...

for example tropicana metropark landscape are built as part of the attraction to sell the surrounding properties that they are developing... they will heavily promote their lake park and landscape to attract buyers for the properties that they are selling...

or Sunway Serena... the man made lake is one of the main attraction point that the developer create to market the residential blocks that they are building within that area... it is not an afterthought idea where they have sold the units only then they create the lake.... it is created solely to ensure they could attract buyers to buy their residential properties in that location..

Exism clearly have no plans to do any sort of landscaping or "attraction" from the beginning  .... as of to date they still have not announce anything about any landscaping yet despite already at mid stage selling all the residential properties that they have planned...

No developer is that dumb to sell off all units ... and then last minute build something that does not generate profit...
Also... as many have pointed out... the so called artist impression... doesn't look like it comes from the developers...

the quality of the sketches doesn't seem to match the other artist impression photos that the developer has shown...

the developer has not use any of the so called artist impression during their marketing campaign ...

the artist impression has the developer brand name on it which as others have mentioned... developers do not show their brand logo on any artist impression photos due to legal issue... it is likely this was being done by 3rd party agents in a desperate move to push sales...
and finally... these so called artist impression photos that some agents here claim they have early access to... are still not recognised by the developer themselves after 6 months....
