OK - so 2+1 = 3rm flat which is actually 2rm but since no utility so why +1? What is the +1 for?
3+1 = 4 or 5 rm flat huh? Do you mean these are 3 bedrooms with 1 utiity room hence the +1.
As i mentioned, the +1 in HDB terms refers to the living hall
With a utility room, it is 2+1+1
To add to confusion, I see newer flats that are for rent saying 2+1!!! OK I know these are brand new flats in Sengkang/Punggol so they cannot have retrofitted utility rooms. I also know that they are 4 rm flats so why 2+1?
Actually I understand your listing but it is when I see new 4rm flatsm(actually 3 bedrooms) listed as 2+1 for rental that confuses me.
This is very simple. There are 2 scenarios :
1) a 4rm listed as 2+1 might means that 2 of the bedrooms are hack and combined into one. Making it a 2 bedroom unit
2) It is not a HDB approved unit as the owner will lock up one room. As of 1st Feb 2010, HDB stated that locking up one room and rent out the whole unit is illegal. Thats why now you dont see ads with "lock one room"
So it is a 4rm HDB flat but you only have 2 rooms.
