Underground Build

Hello fellow shroomerites, I come to you today to ask some questions and bounce ideas off you guys and possibly inspire some people as well. I love building things of my own using skill and knowledge of said things and seeing it come together is the best feeling in the world for me. I am planning on building a small underground storage space located under my living space. I have never built a basement or anything underground for that matter, but I have done an extensive amount of research on bomb shelters, basements, and cellars and believe that I can do this myself with some time and effort.
Some background on the build - I am currently living in a mobile home which as you may or may not know is sitting on concrete blocks about 4ft from the ground (please hold the "white trash" comments as it is quite large and nice). The blocks holding the frame are staggered and vary on the locations underneath. Generally though there is 5 - 8ft between each stack. I plan on digging a 7 x 7 x 7 ft hole and building a 5 x 5 x 7 ft storage space within this hole for my hobbies. I am going pretty cheap on this just because i'm not trying to build a bomb shelter, just something to house my precious pals that do not get much sympathy from some people in this backwards world. That being said, I will use 2x4's as braces on the walls, ceiling, and floor then use plywood to close in the room. Once this is done I will then use some pvc piping for intake and exhaust mounted to a box with a hepa inside. The pvc will also have a inline fan located in the middle to suck in air from outside every hour for 5 - 10 mins. Once this is done I will epoxy the holes and make sure its as airtight as possible (besides the intake and exhaust holes) and tarp over the entire room to prevent excess water leakage. As far as temp and airflow, a small heater and fan should be sufficient with this size room. And electricity is the best part, there are outlets underneath my home that can easily be disguised as wires just running under my house so there is no need in installing it myself(i'm no electrician). I'm thinking the entrance will be the last step, maybe a hole with culvert pipe and a ladder because stairs do not seem a viable option for this.
So now that you guys know what is going on I have a question for anyone that cares to answer. The blocks that are holding up my place, will they become structurally unstable if I dig a large hole in between 4 or 5 of them or should it be alright? That is my main concern as having a large house fall on top of you would not seem survivable. I'll try and post some pics of what I mean so you get a better picture, but its been raining quite hard all day today and its preventing me atm. If you have ANY and I mean ANY advice, ideas, or just some facts that would help me alot. Come on shroomery, lets build a ..... cellar????

Although I would imagine that if one post became unstable it would probably be ok, I would not advise this plan in any way. Plus having a hole down there without having a gravel barrier around cinder blocks or something will surely be prone to water flow and sidewall cave ins.

I thought this same thing also. But to counterpoint water flow, i've been watching the small amount of rainfall we've had this season, today being the greatest it has in a while, and surprisingly 90% of the dirt underneath stayed dry each time. I believe it has to do with fact that I have a garden framed with wood planks all the way around my house that acts as a barrier against rainfall. Plus I was planning to use bricks and left over dirt from the hole to form another barrier from the inside. The sidewall cave in gives me some worry though, defiantly wouldn't want to be caught in that. I suppose I could use cinderblocks in the corners offset, drop in the 2x4's and then concrete them. Rebar and walls made completely of blocks are out of budget right now im afraid. What would you suggest?

you're looking at an engineering nightmare to try and do this while the mobile home is in place... there's a lot of risk involved here. now let me explain the danger. the walls of a trench can collapse, depending on the composition of the soil you could be looking at 40 tons of dirt falling in on you and then having the home fall in with it
if you have 8' spacing between your piers then you can possibly make a 5x5 room without risking the piers collapsing the sides while you're digging it out. you'll need to use concrete or plate steel for your walls and all of that will need to be boxed with bracing on the top and bottom and something like this will be no easy task, the box would really need to be built and set before the home was placed

You would not be able to accomplish this unless you went straight thru your living room floor which this is not the time of year to start that but it might be ok where you live. I would go thru my floor but excavating the dirt is going to be a bitch. you will have to use something other than plywood and also you would need a sump and liners on the wall for waterproofing or something other than a tarp. 5'x5'x7' is a decent size hole. I could mention a few other things just to start. But my concern is that you want to try and build an underground strage shelter beneath your mobile home all by yourself but you can't do a simple procedure like instal an outlet. I am by no means an electrician but outlets and breakers are a piece of cake. I installed a dedicated gfi for my reef tank and it took me a whole fifteen minutes to run the line instal the breaker and hook it up. I just dont think this is a smart idea unless you have some funds to back it up. this is going to affect your home. If you did it right you could have a secret acces panel in your house somewhere. Wiat till you have more money.

Can you not try digging a hole in your garden? tell people its a beer/ wine cellar?

Can you get a shed?? I live in a mobile home and have a shed...it seems to me like it'd be much easier to build an underground room underneath that thing than the actual home.

I do have a shed and am now just contemplating digging a small tunnel I guess you would say, a 3 x 6 x 5 to be exact. I'm thinking this will counter the major weight issues but will also require more materials as this area is more susceptible to water fall than under my house. The shed is roughly 6 x 12.

seriously, engineering is your issue here, if not done properly you're going to have a cave in and if you're unlucky you will be buried alive, luckily though, the weight of all that dirt will crush you so you wont be living for more than a few minutes
if you're determined to do a project like this then plan on doing it right because there's no way to do it a little at a time and with crap you can get at home depot. make use of the shed to conceal your entrance but bury a shipping container or buy a storm shelter, rent an excavator and dig your hole, bury the container and set the shed on top. even with doing that you're going to have to reinforce some things to keep the container from collapsing under the weight of the dirt
old containers can be picked up for about $500-$1500, the excavator could cost around $100-$300/day depending in size http://googlebordello.crushhumanity.org/internettreasures/container/yourself.html

Buy a bus, rent a backhoe. People do it everyday?
