if you want all these listed within walking distance, no. closest is setia alam and it doesnt have all these yet, but in the masterplan...

Actually if you really want to count, Kota Kemuning is having all these requirements, just the international school is from Taipei
One more extra feature it has is it got a 18 holes golf course inside too.

However, for your budget, you can't get really very close walking distance to the lake front (unless you don't mind walk more than 1-2km)

Then you need to go to KK to experience yourself loh, especially during weekend evening around 5pm at the lake side area

Personally think Setia Eco Park (SEP) is nicer than Desa Park City (DPC).
Condifent also SEG will be nicer than SEP due to the waterfront - 8 islands concept and past experience from SEP.
However, commercial activities - no one can beat Damansara / DPC that's for sure even though shopping malls in cyber are mushrooming everywhere.
But, comparing a 22' x 65' house in DPC asking for Rm 1.4mil and SEG 26'x95' = Rm 1.1mil+....what else can you complain
