Jumbo/multi generation units

The term Jumbo/multi generational units is very confusing,as it is often used to refer to three types of flats.The first type are basically two units merged into one big unit,all done by the owner himself/herself,or the Hdb in case of some rental blocks that were converted to larger owner-occupied units in the 80s-90s(needing confirmation).

The second type refers to multi-generation units the HDB built in the late 1980s.These apartments were basically pre-determined units combining one 3-room simplified with one 4-room simplified,and are approximately 148sqm in size,and have two kitchens and three toilets(!),all in the space similar to that of pre 2000s executive apartments.Only seven such blocks were built,and were all completed in 1986/87 (Bishan 137,Tampines 454,460,Yishun 605,632,633,666).

The final type refers to some extra large executive apartments the HDB  created by joining 1970s 3-room and 4-room units together in the mid-90s,with fresh leases.Most of them are found in Woodlands.

In this article,you are going to learn about the three types of jumbo/multi generation units,begining from type 1.

Type 1
These units can be hard to create.Firstly,you must own one of the two units that you want to convert into a jumbo unit.Then,select one unit,either the one on the left or right(depending on the location your unit is placed),and try to convince the neighbouring unit to move out.

Next, acquire the unit mentioned above.Knock down the walls(except for structural ONES!)as much as you like to join the flats ,if you like it.

Sometimes,if the two units are located at the very end,you can add in the corridor that previously separated the two units,for a fee.

However,take note that merging two 4 room flats,or bigger,or merging 3 units and above is not permitted.

Finally,decide on the number of xrooms your unit will have.How many living rooms/bedrooms?The only limit is in the structural walls.

Here is a possible list of jumbo sizes.Have fun!
