As long as I get 5 room with balcony in northshore cove, will do for me.
I think you need to do a detailed analysis yourself based on the needs of your family.
Many friends told me that they would like to have balconies so that they could have tea and play a guitar, or one of the rooms to turn into a corporate office.
Take a walk down roads that build condominiums. You will see that you are paying so much more for a place to do your laundry. A room used for office? Ending up with a gym bench and whatever not - junkie room.
I am not discouraging you and this is my own opinion. I would think short and long term for my family needs. Not whether its high floor or balcony that looks cool, feels cool. Its a needs based decision that I know it will affect my family in the future.
I am sure you have received the packaged in myHDB. I do not know if you have kids or planning to have kids. The moment you decide that you need grills due to your kids safety, you are limited to the options stated in the brochure. It could potentially looks horrendous for you who have spent a bomb to make your home and balcony looking like a billion bucks.
Think carefully. Weigh your options and put your family needs first.
Peace
