Belly down, just 4 needed? Sorry I might be misunderstanding…

Yes I know you’re right. I’m in danger of over thinking and introducing unnecessary complications. I guess my thinking was that without achieving depth for the higher piers (with solid ground being hardwork) I could instead gain some width. Btw - the pipe is placed in position and then filled...

I’ve had a mini digger in this garden a few times. Grading the driveway was just about ok but further up in the garden I’ve worked on ground which really needed a breaker attachment. Without it the whole thing was lifting quite controllably off the ground. On the topic of my base, I have approx...

Very helpful thanks. I live in the Cotswolds and our ground is virtually rock. Removing it to then replace with type 1 always feels expensively wasteful. You end up removing well compacted stone and grit, only to replace with the same.

Quick question for those in the know… Is there a max size building that this type of base can be used for? I notice MikeG in his ‘no concrete’ thread says only to be used upto 20m2 I think.

Re. walls. I guess this is the thinking behind internal osb? Any moist air hits the ‘warm’ osb, minimising condensation, and any moisture that does make it through, is able to escape through the breathable membrane? So the question is really for all those residential buildings and loft...

Thanks all understood. I was really trying to figure out the horizontal dimensions before thinking in much detail about the verticals. Having worked a little bit with plasterboard in the past, i’d much rather be making cuts to that. So if I keep the OSB on the exterior, it would make sense to...

Hi Martin Looking around, 2700mm osb seems to be less common. As you’d expect. Given current pricing and availability of materials this just feels like I’m not going to get the best price. What do you think about this idea.... 3.6m top/bottom plates, using 450mm centres gives 8 equal studs...

Same size as yours about ideal for the plot. Although I can fine tune now to make the whole build more straightforward. Span tables... yes, although I have to hold my hands up at this point and say calculating the dead loads is completely out of my current level of understanding. I think (1)...

Interesting. I had seen this in Mike’s design as well as others online. But like you say, hard to adjust when the majority of framing you see online places OSB on the exterior. I was probably thinking of doubling up and using osb on outside and inside of the frame. However, concern with that...

Yes that’s where I was going with it...! :ROFLMAO: Plasterboard is also available in 2700mm lengths so I think that’s why Robin says it works so well. In terms of wall height, that’s a very good point about internal height and I’ll have to give it some thought. Externally though, since I’m...

Yes makes sense thanks Martin. Floor... I’ve previously used 18mm ply for flooring (albeit on smaller non-insulated ‘practice’ sheds :)) again sold in imperial. And I did line up the joins with joists. I’m assuming the T&G boards don’t need joins fixing? If so, a good reason to use instead of...

Point taken. But pricier to waste?

Hi Martin Great read, thanks. I’m currently planning a very similar build, although located in AONB and well over 50m from dwelling house so planning req’d. One aspect I’m currently mulling over... the old chestnut of metric/imperial, sheet materials and reduced cutting/waste. I noticed you...
