Hi Jaspok, Executive condos happen to be my passion and you can find info about any EC (both old & new) in Singapore on my website here. Both 1Canberra and Heron Bay 3br units will fit your budget of $600 - $750psf. Currently there are still fair amount of 3 bedrm units left in 1Canberra. Chances are that you can still find your choice units by Sep. There are 3br compact (without service yard), 3br standard and 3br dual key available now. you can find more details such as unit size here As for Heron Bay, it's expected to be launched in mid Sep, so it should be quite timely for your consideration since your HDB appt as mentioned is ard Sep/Oct. This is a smaller development compared to 1Canberra, offering 394 units vs 655 units.
