I'd say something like 12-15k per square (9m^2) is reasonable considering building new is like 6-8k per square. The extra cost is to cover contingency because of the unknowns when dealing with something already built. http://www.homedesigndirectory.com.au/c ... age2.shtml Hey, I am wanting to add a second toilet to my house, bit we have limited room.
