I got this from Building Construction authority website. Random
sample, did not search through, so may not be representative of
average project. Just want to give a rough feel.
ERECTION OF 115 UNITS OF 3-STOREY STRATA TERRACE HOUSES WITH ATTIC,
BASEMENT CARPARK AND COMMUNAL FACILITIES ON LOT(S) 4402L MK13 AT
SEMBAWANG WALK - Project cost S$35,000,000.
I average out, 115 units, ie S$304, 347 per unit.
Lets suppose each unit is about 2000 sq ft (its 3 storey) and 4-rm
HDB is about 900 sq ft so that works out to about $137K per 4-rm
HDB size. I suppose the build quality of private house is more
demanding but the cost of material is the same, and each HBD flat
will require toilet, bomb shelter and water pipes, consequently
making it more costly.
Note this is only construction cost, have not included water &
electricity testing and connection, cable TV, telephone, clerk of
work, architect, clerk of work and other cost. So another 10-15K
per unit, I suppose, is reasonable?
Also, there are amenities around, like roads, bus stop, schools,
lamp posts, sports facilities, which will add to the cost of
building a small town.
Not sure if this calculation is fair. Any civil engineer or
contractors out there??? HELP!!!
