The executive condominiums are designed just like your regular condo. Developers who carry out the projects are usually private ones. The only difference between the regular condos and the Executive Condominium is the lease which isn't freehold but covers a period of 99 years. One of the things you should know is that you can apply for a housing grant just as is the case with the normal Northwave EC Singapore. The executive condominiums are also usually sold and built by various private developers who are well known in the construction circles.
