Sunken Greenhouse - framing, polycarbonate install how to

This video brought to you by backwoods home magazine, hey there guys welcome back today, is going to be part three of the sunken green house project and, as you can see behind me, it's really starting to take shape. I'M so excited because for so long it's just been a hole in the ground and really pretty ugly, but I have been able to get all the framing up and paint it and get the polycarbonate panels on and get it closer or almost to the point where I can use it as a greenhouse, so let me show you all the steps that I've taken to get to this point and then, after that I will grab the camera walk you around just so you can kind of see the exterior facade and then I'll. Take you down into the greenhouse to show you a couple of things. I'Ve done and talked about a few of the other things I still haven't done or things that I need to do. The first step in making my roof structure was to build a ridge beam. I'M carrying it to the greenhouse right here, it's made of three 12-foot long, two by sixes and I bolted them and screwed them together. Once the beam was leveled and braced in place. The next step was to build supports at the end and then fill the middles with Raptors. This beam will eventually have a middle support, but I don't have it just yet now, I'm attaching the doorframe to the block, columns, fitting the door in and checking for a good fit after that was finished. It was time for a little paint and boy. I'M glad. I bought this sprayer when we built our house and right here, I'm installing the frame for what will be one of two or three vent windows, I'm not exactly sure where the second third one will go, but at least we know where this one is and to Cover the greenhouse, I'm using tough text, polycarbonate panels that I got at my local Lowe's. I chose these panels for a variety of reasons, but probably the main reason is because they are so resistant to extreme temperatures. Additionally, these panels are supposed to be extremely durable and rugged, but they do require some special care during installation. Specifically, you need to pre-drill holes before sinking the screws. This will aid in helping prevent micro cracks from forming years down the road. As for placing the screws for horizontal surfaces like roofs, you're going to want to place them on the Crown's of the ridges, and if something is going to be under flashing or in vertical surfaces, you can place the screws with in the valleys and to trim the Panels it was super easy, as I just used a circular saw with a reversed plywood blade and for the edges of the roof. I added galvanized flashing to give it a clean look as well as to aid in wind and weather resistance, and on a side note, I think I found the first manufacturer that actually installs stickers that can be torn off easily and now. Let'S take a look at a few final shots of the exterior of the greenhouse and then I'll. Take you inside it and talk about a few things I have coming up and here's a quick little look at my landscaping through they work hard. They tilt ask for too much. Okay, now that we're inside the greenhouse, you can definitely tell it feels much more like your greenhouse and I'll tell you temperature-wise. It definitely feels more like your greenhouse, it's almost a bit humid in here, but overall it feels pretty nice. So the most obvious change that you won't noticed is I added a door. I just framed it up attached it to the columns with those bolts that I had sunk in when I was building the columns and then just framed out a door, and I covered it in the same polycarbonate panels that I did the whole structure with. I don't have a handle or latch yet, but that'll that'll probably be in my to do list. Ah, the next thing in here that I had meant to do was this ridge beam up here. I have it's probably about seventeen and a half feet long, and I do intend to pour concrete, footer right here and install some sort of interior support. It doesn't really sag or anything right now, but over time. It is something that you do want to have. I don't want a longer than a seven or eight foot span without some sort of support, so that will probably be in the next part as well. So let me take you to the other side of the greenhouse and the most obvious things here are going to be the little vent door that you see up here. I don't have a latch for that and I don't have a polycarbonate panel on it just yet, and the other portion is this little vent hole. I talked about this in a couple of the other. I guess parts. This is something that probably not going to address for at least a month or two so I'll probably have the last greenhouse video up and then I'll just do this. When I have time but like I said before, it's just going to be basically I'm going to trench a long trench, maybe 150 feet it's going to come out at the bottom of a hillside and hopefully it's going to direct a thermally cooled air into the screen House during the summer and thermally warm tear air into the greenhouse during the winter, but anyway right now it's just a hole in the concrete, and if it does look like it's not quite a straight line, this is just from my foam support when I poured that Concrete it it just sagged, it's not currently sagging right. Now, it's structural. It'S got a but a bunch of rebar in it. So let me take you to the next part, okay, so the next issue at hand. I feel like these videos are starting to look the same, but these steps - this is still kind of my nemesis. I said that I had planned on doing some sort of gap yawns or something up either side and then building some formed concrete steps or something like that. I am still not sure what I want to do. I may end up doing some sort of railroad tie thing on the sides and then tying them into those dead man anchors that I spoke up before and speaking of that this wall, where you had those where I showed you this little PVC pipes last time, they Still have exposed PVC pipes and I'm trying to be realistic with myself right now and I'm probably not going to get those finished for a while. Now, I'm probably just going to leave these this wall be the way it is just for this coming up summer. Just so I can get onto some other projects and that's pretty much it so I hope this updated. You guys. I really did not intend for this to be a part three or four or five part series, but it probably is going to be part four or four parts, so the fourth part will probably be like landscaping. These stairs and oai needed add another event up in this top of the ridge. I just didn't have time to do it right now, but that will be kind of what the next phases of this greenhouse and then maybe building some shelving. So I hope it was informative and hopefully maybe it gave you guys some ideas of things and you can see my chickens trying to explore in the background and then, if that's all, then I guess we'll see you guys next time and thanks for watching, if you Like this video, please give it a thumbs up, and if you like, do-it-yourself projects and other self-reliance oriented topics, please consider subscribing for more future videos, see ya.
