House extension, single brick, double brick, blueboard . What would you use ?

[dave289]

I am doing a house reno/ extension shortly and was wondering what peoples thoughts were on different materials. The house is already double brick and I was thinking to keep it double brick. The Thing is in the last month I have had my mate, who has done a owner reno, and says to go single brick as it is cheaper. My neighbour who is a builder says he would build his extension if he was to do one in blue board, just as he has recently done his new garage, my other neighbour who is also in the building game said he would do an extention in blueboard ,just as he has done with his laundry out the back.my oldies did a reno a couple of years back , they extended their house and also used blueboard. They argue its much cheaper than double brick or even single brick for that matter. The extention will only be another 50 sqaure metres , 8 by 6 meters. I like things built tough and dont think the savings would be that substantial for the end result. What is your opinion on these products and what would you use ?
