Wow! That's pretty significant. I'd probably confront the landlord about that. You should be able to find out if that happens every wet season, or if it's a fluke. If it happens on a regular basis, the landlord should have disclosed that. I unfortunately had a few dishonest landlords when I was renting.

Yeah, I'd push the landlord but I doubt much would come of it, based on my recent experience with her. I spoke to the neighbors and they think it only happens every year or two like that, so I can accept that - I'll just do a couple of things to improve the drainage, and then clean up when it gets really bad - I'll put the pads on some pallets also, so they don't get wet. I got stuck back into it yesterday and put together the bottom half of the frame. I'm starting to realise that because I am not securing the frame to an existing structure, that there is a bit of potential for sideways movement in my design. In order to combat this I think I have to add some serious cross bracing to guard against sidewards movement. See below ideas in red where I had not intended to add bracing, but now thinking to put it in. At the back I'm thinking big cross braces on the back wall component, and then on the front, a couple of small braces on the bottom to counter sideways movement at that end of the frame. I believe the actual 40 degree wall framework will act as a brace against backward movement of the frame, but I think I'll also need to add a couple of braces to the sides to guard against forward movement. I'm sure I'm overengineering this thing, due to my lack of structural engineering knowledge, but I'd rather do that than have it collapse on me.

Do you remember the wall you climbed on at my place in HOU? 40 degree completely free standing with no sway or any other movement with a person on it. Far more simple design. Two pieces of ply were framed with 2x4 on the edges and across the back every 2 feet, then screwed together at the point they met (middle seam). I took three 2x4s and ran them across both pieces of ply to connect the two framed ply pieces making them one. A 2x4 connected them at the top, middle and bottom. The bottom of the ply sat on the ground. The rest was screwed into a 2x6 (standing tall) and a 2x4 (laying on the ground) to form a triangle. Metal brackets and pocket screws were used to make the connections sturdy. Terrible picture below. It was all I could find. You can ignore the vertical stuff. It was a mostly useless afterthought. Whatever the case, hopefully it helps.

Thanks A! I got stuck into it today - I think I've really overengineered mine. After I built out the frame today, it had a lot of sideways play. I added bracing to the back and front. It now feels bombproof. The front bottom is now really stable. The top at the front still has some play but I think that when I put in the 40 degree it will reduce most of that.

Adding the plywood should stiffen things up and possibly reduce or eliminate the need for that cross bracing. But having a floppy woody could be embarrassing, so I don’t blame you being worried about it

Would you be able to seal the bottom panels or remove then in the event of further wetness?

Would you be able to seal the bottom panels or remove then in the event of further wetness? I sealed them with a couple of coats of marine lacquer. Screwing into them will have reduced their waterproof..ness, but I think will help at least somewhat. I'm thinking about taking other measures to reduce the possibility of it getting wet and reduce the impact if it does get wet.

Finished the wall yesterday and pretty stoked with how it has turned out. With the ply now added there is virtually no movement in the structure and it feels solid as a rock, even with dynamic sideways movement. With the frame up in the picture, there was still some slight sideways play - about an inch - at the top of the frame, but once the ply went on, it completely firmed up. I'm yet to put the holds on - building this thing has been really exhausting. I filmed time lapse shots of most of the construction, so I'll post that up when I've edited it together. Thanks for everyones advice, particularly Tetrault - who made a google sketchup for the design.

Nice work! Great use of your space, do you think you support beams will ever get in the way on swinging movements?

Nice work! Great use of your space, do you think you support beams will ever get in the way on swinging movements? Thanks! On the bottom photo there you can see the yellow hold, which is the finishing hold. My head is still 2 feet away from that beam when I hit that finishing hold. I was thinking about putting a layer of foam on it, but based on watching a couple of videos last night, I think it should be fine.

Thanks! Put some more holds on it last night - got about a 1/3 of the holds I bought on the wall. I really need to leave it alone because I'm nursing a back injury still, and need to rest, but every time I get home from work I just want to work more on it. There are some holds which are probably not going to work unless I put them on volumes. The big purple slopers are really hard on the 40 degree angle, but I want to use them to set some compression problems, as compression moves are a weakness for me. I also bought these sweet sandstone seams from kilter grips, but they are going to be useless on the 40 degree wall. I've actually drilled a few holes in the top of the wall on the upper beam to create some finishing holds above the wall. Could be a good use of those holds. Has anyone built a volume without a table saw? Anyone know of a way to do it without having to cut long bevel edges?

Damn, look at those biceps! Did you build the wall by holding the plywood with one hand and the drill with the other? I have no doubt that you did. But I agree, those purple slopers aren't going to be very useful on the 40-degree. Maybe you should put them on the kick board and do some run-and-jump type of problems... you know, world cup style. (Clearly, I'm kidding... wear a helmet if you decide to try)
