After getting plans done up for extending out we are stunned at the builders quotes for the cost of it (the roof needs to be raised for the extension) we're now wondering if building up would be that much more expensive? Our current house is 108sq metres-we had planned to build out 9 metres length (5metres indoor with a 4m deck) x 9m width.
Advantage to building up would be keeping more of the back garden which with kids would be great. I don't see any disadvantage except if the cost is way more...?
Would love to hear from anyone that summed up the cost of both options and/or any tips.
