Garden Shed Frame Work

howdoyoudo2103

Hi all, just in the process of building a small garden shed 15'X10' lean to style. I have put down a course of 4" blocks on the flat, two blocks high around the perimeter/walls to create a water barrier. I intend building stud walls on top of the blocks using 4"x2" and then sheeting with box cladding. Also using 4"X2" for the roof rafters and again non drip box cladding. Question I have, is it overkill to use pressure treated timber for the stud framing, could I use non treated or would using metal studs be an alternative option? Thanks in advance

I'd go pressure treated all the way, the stuff I get is cheaper. I'd also treat all cut ends and the joints with something like Protim 265. I'd also put an extra 4x2 below the 4x2 thats part of the stud work as if it does start to rot you can slip it out and replace it without affecting the stud work. However I nearly always over engineer :-)

Edit> You'll probably get better quality timber if you get untreated so really a trade off.
