Housing/Shelter talk:
Looking for any and all ideas regarding new housing, starting from scratch.
Tn, I remember you talking about 8" walls. Up here efficiency is a primary concern. What would you say to 6" walls with blown in expandable foam instead? Then everything can be standard. I used it on a rehab project with 4" walls once, and it made a huge difference compared to normal methods. I too hate Tyvek, worthless crap. Is there suitable replacements to achieve the same in theory? I have tried other housewraps, and have had no trouble to date, whereas Tyvek was a spendy lesson. Would probably use stone/stucco combo exterior, so the paper has to deal with that. No plastic siding for this one. Up here, standard is forced air furnaces run on Ngas or Propane. I would prefer to do an outside furnace system, pipe in hot water heat, and have a possible loop system for cooling. Haven't totally designed it yet. Ideas? Was thinking a possible split system for summer and winter. Winter it runs through the exterior boiler, summer it runs through coils underground to cool the water and back through the heat exchanger. Was thinking of exterior building housing the backup generator, the heat system, and storage for fuel. Fuel storage underground or above ground? Will be well and septic, so I won't be on the city life line. Any special requirements on a food storage room? Years ago, root cellars were common, but now? When in Alaska, we just hung stuff out the windows to keep it frozen. Dehumidifiers? Humidifiers? Air quality? Ext finishes? Int finishes? Asthma friendly? The place it is going doesn't have earth berm capabilities, or I would entertain the thought. Been in the business a long time, just want fresh ideas to incorporate, instead of the same old crap churned out by all of us. Gonna start drafting it up soon, and the old saying two heads is better than one came to mind. |
Re: Housing/Shelter talk:
If multi story, consider ballon framing. You can insulate th areas between floors better. Maybe?

Re: Housing/Shelter talk:
Latest rage is for "Greenbuild" products.
Leed certified giving tax/mortgage breaks. http://www.nudura.com/Content.cfm?C=...MI=646&L1M=646 This is one of the many products we are using. Same cost as wood. http://www.litedeck.com/ ^^^crazy stuff^^^ Subs go up a hair for elect./hvac system. Will put you in contact with the factory rep. if you wish. |
Re: Housing/Shelter talk:
QWAK,scorpio,Don't know if this would be helpfull or not but you mentioned "Dehumidifiers?" I have one that I riged up with a small float activated pump and it takes the moisture out of the air and what you get is almost distilled water. So it could posably be used in EXTREAM situations as a source for drinking water. I plan to set it up so it adds water to a big FISH TANK when I get some more stone leveled to be the suport of the tank. The fish tank will be sort of built in to the stone wall.
I had a friend who took an old FREEZER (a BIG one) and cut a side out, instaled GLASS and built it in to a wall of his basment,it was behind his bar and he could kick back and go FISHING any time he wanted! :haha: :hahaha: Its UNCONVENTIONAL and not very expencive to build. It realy was COOL ,the fish in that big tank!:haha: :haha: the DUCK |

Re: Housing/Shelter talk:
Whew...tall order. but I'd love to design one from the ground up....SO much you can do nowdays.
Ceiling insulation......I'd be going for R-50-60 up you way. Mine is 38 here. I'd shoot for R-30 walls up there at a minimum, however you have to get it. If you go with 6" walls, and foam in place ( I don't know what the R value of the foam is ), I would also go with a 1" foam on the outside to cover the studs.....otherwise, they are the weak point in the link, bleeding heat at each wood point. My own walls are double 2x4 with an 1" of foam on the outside of that.....the outer studs are on 24" centers and the inner wall on 16" centers, with about 1" separating them....they join together at the top of the wall with a plate of 9" x 3/4" plywood across the standard 2x4 plate. Overall wall thickness is 10". I wouldn't worry about staying with "standard" wall thickness.....extension jambs for doors and windows are no real trick to make. My windows ( Andersen Casements ) have lovely red oak extension jambs, seats and headers that are about 8" deep.....wife loves 'em for places to put her weeds...er, I mean FLOWERS.....ahahahaaa I know due to frost line, about every home up there is built with a basement.....and then a convention wood floor. I would consider a 4" concrete floor even though it required more support on the basement level. About 2/3 of my first floor is on concrete slab on grade, then the rest on full basement with wood floor. If I had to do it again, I'd go concrete all the way thru.....then run PEX tubing in the concrete for heating. Think MASS. I also built a MASSIVE chimney in the center of our house....I have no clue how many tons of masonary mass is in it, but it's a LOT. The chimney is 6' x12' from the basement to the point it goes out the roof ( then I reduced it to a normal looking chimney) and includes a brick wall in the living room and the bedroom side. The advantage of large amounts of MASS is it tends to moderate temperature swings. Once you heat it up, you have a LOT of heat tied up in that, and it only takes a little bit to keep it going. PEX infloor heating wasn't much of an option when I built mine, but today, it's the only form of heating I'd consider. This would mesh great with that outdoor furnance you've been looking at. For cooling, you could go with a convention ducted AC system of course, but I'd also look at zoned mini split systems. Another advantage of massive amounts of insulation and mass is the cooling side is also easier. Our house stays fairly comfortable until late July and August, and even then only in the late afternoon. I did not put an AC system in when we first built.....I added a Mitsubishi mini system a couple years ago, and it works GREAT. Quiet....no ductwork, installed it myself basically. Have no idea about humidifiers or dehumidifiers up there. As to air quality, I'd be looking to make the house a TIGHT as physically possible, then look at a fresh air intake with a heat exchanger. I'd also design every exterior door opening so it was "airlocked".....no exterior door opens directed to the outside.....you have vestibule or enclosed porch that you enter, then the exterior door. A separate building for a wood furnace and generator would be great ! I'd go for a small diesel generator.....5-10kw at most, and get one that produces at a low RPM like 1800 or less for long life and less noise. If you can build the building back into a bank, that would be great.....muffle the generator noise, then put an underground tank on the bank side and gravity feed the generator. I'd also seriously consider the setup Rich G has with batteries and inverters....that is the MOST efficient way to use a generator. Batteries supply you with power when you are off grid power, then the generator recharges the batteries when they discharge to a certain point, the inverter controlling the start and stop of the generator. That way, you aren't running a genset to power a few small things running ( like a single light, or even a refrigerator ) that aren't using anywhere near the capacity of the genset. Instead of running 24hrs/day, it may only run a couple hours a day.....when you have a peak load. I'd go propane with every appliance that requires heat.....stove, dryer, water heater ( go tankless ), and any supplimental heat you might want for early fall or late spring when you really don't want to fire up the wood. Propane you can store to an extent....NG puts you at the mercy of others. Exterior finish ? Masonary would be my first choice.....stone or brick....mass, mass, mass.....plus low or no maintenance. Pay for it up front and forget it. Interior....lot of choice there....if asthma is an issue, avoid wall to wall carpet....hardwood and tile rule. Food storage room I'd take some more pains with......every 10 degrees you can lower the average storage temp of food, you increase the time a LOT.....I've seen figures in the 50% range......I'd shoot for earth temps of about 50 degrees year round for most storage goods. But you have to have low humidity for canned goods and such so you don't get rust....and just about the opposite for fresh foods like potatoes and apples.....so there is no good mixed multipurpose room that will work if you plan to do both. Security ala concealment for food storage would also be a strong consideration IF I was going from scratch......have a couple thoughts I'll PM you if you want. |

Lots of independent research in it as well. E.g. 2x4 steel stud then plywood added to exterior walls or a safe room and filled with 3/8inch gravel for self healing wall to protect from small arms fire! |
Re: Housing/Shelter talk:
Have you thought about insulated concrete forms with a ton of rebar? Might come in handy if ts ever hit your particular fan. I have worked in a couple of these houses and they seem like a great way to build.
I will be building a new home in the next 5 years on the farm I purchased in TN. I am seriously considering the concrete route. NOOB |
Re: Housing/Shelter talk:
Great stuff guys,
I would like to stay away from balloon framing, as I was never a fan of it. Saw too many issues taking 'em apart. Not to mention, long decent wood lengths are harder to come by, and increase overall costs. Should be able to handle the insul quite well using other methods. Thanks Horn, bookmarked them. We have versions of the lite forms around here, and I haven't used them to date. Might be a time to start. Noob, hit on those links, as I agree with you. Horn also hit on floor systems using concrete. Duck, now that sounds like fun to incorporate, a tank and fireplace for a rustic interior look that I will be after. Kahlil, I am with you on that one. I have come to believe that FG is just old technology, that is inefficient comparatively in this climate. Many Swiss houses I believe are using panelized construction with foam and two layers of sheathing, with no studs, except at buck openings, or load bearing locations. I was wondering about incorporating that style with the roof and walls. Yep Andy, tall order. Trying to balance overall cost with efficiency. Would rather spend the fiat on 'smart' tech than on frivolous crap that it seems every yuppie wants now. They have no structure, but by God they have a Jacuzzi. That foam is 5 per inch Andy, so would get over the 30 hump, as I agree with you. I was thinking along the same lines, 6" foamed with 1" over the top, but a panelized system may be more economical for the same effect. Yep, Pex is the way I was leaning, and then piping heating and cooling in and out. Cooling would run through a transfer coil and fan system. Makes sense on the airlocks. Make up air is standard here when we get that tight, or you can die :beer: Not too hard a choice. Yeah, saw that too. Thought RichG nailed it there. Propane is easy to get around here, and I can move a couple of my big tanks over for storage, and will use it as primary backup system. Agreed on the mass thingy. Old style log homes, with real full cut logs banked on the mass technology. Still makes sense. Everyones idea of introducing concretes, and other high mass items fits right in. Seems like on the storage tech, a guy is partitioning storage. One for dry goods, and another for more humidity. That was interesting. Easy to add foundation before you start. Need to determine if going up 2 instead of sprawling out on 1 level. Didn't really want to go with the typical 2, but will have to balance the cost of going up vs out. Keehah, never heard of it. I'll review the site. Looks like one needs to get his book, is that it? TIA guys, all ideas are welcomed. Not building a mansion, doesn't fit me. Want something laid down rustic and efficient for the future. The anti todays building methods or anti suburb house. Tn, with a 900' drive, will be incorporating some of your ideas from the meet. Haven't decided on fence and gate entry yet. Seriously considering hand held opener gate control, like your garage door opener. |

Scorp, give me a PM when you are ready for a gate opener. I can see if I can swing you a beta test one gratis.

Re: Housing/Shelter talk:
If anyone is worried about tornadoes, security, nuclear blasts, fallout- consider the monolithic concrete dome. We have three of these near us... wow. You're behind about 8 inches of reinforced concrete (what I could see near the bottom in a doorway). Nobody is going to drive through your walls in nothing less than a sherman tank. Heck, you could backfill to hide it. Fallout- I'm not sure how thick you need it, but you'll fare the best out of all your neighbors... you have to properly cover openings... but compared to the non-existent protection of a wood framed house- sweeet.
http://www.monolithic.com/ Follow some of the links- they're neat. |
Re: Housing/Shelter talk:
OSCO brand is the best residential opener I've found ( Operator Specialty Company ). At the time I bought mine, they were all eletro-mechanical switches.....not a circuit board in them, which was a weak point in the previous brand I had.....lightening running in and 75 bucks a pop for a new board 2-3 times a year.
But a buddy of mine here just put a set in and he said with the new weenie govt requirements about safety issues, they finally had to go to an electronic version. shame.....but still a great opener. They don't sell direct to the public....I bought mine online thru a fence/gate dealer in Ohio. http://www.operatorspecialty.com/ While you have the ditch open to run an electric line to the gate area, be sure to drop in a video/audio cable too. Nice to actually SEE who is at the gate, and decide whether you want to put your pants on......ahahahahaaa The control for them can be matched to your garage door openers so the same button for it will do the gates. I use Genie for door openers. ( get the commercial version with the solid screw track from a place that sells doors/etc, not the 3 section piece of crap from the BigBox stores that fits so nice in your trunk ) Also put in the Dakota Alert system Rich showed at the meet.....well worth the money. |

Here is something for you Northwoods characters. Do the green thing Scorp. I could entertain the idea of purchasing some off the grid land and building a self sustaining G.I.M. fortress with you fellas. Seems like we would be able to make it work. We could let jerry stay there for free, he could live off the bark on the trees outback.:D Here, I found the perfect concept plan, what do you say Andy? |
Re: Housing/Shelter talk:
I've always been partial to a story and a 1/2 design......couple bedrms and bath ( or whatever you need ) on the upper level, rest including the master bdrm on the main floor. When the kids get gone, you simply shut the doors to the upper level and ignore it. All fits compactly under less roof than spreading out. Up is ALWAYS cheaper than out, both initially and in terms of energy down the road.
|
Re: Housing/Shelter talk:
Flat lot, trees yes, mountains no. The exposed basement walls idea is out unless rebuilding the lot.
Not a fan of two stories, but it is cheaper to go up. Prefer steep slope roofs, so the 1 1/2 could work if designed properly, nesting rooms up into the roof system. Do some rooms up with dormers possibly. Then you can get away from the two story look. There are a lot of horse shit story 1/2's around here, just pure junk as the farmers bought a kit from sears and put it together. They should have stuck to growing corn. Why do I know, currently have one. Was looking at these: http://www.r-control.com/sips.asp comments welcome on that style. I know it is getting pretty sad when I am thinking like Tn and RichG........:bandito: Yep to the digi line, and comm line to the entry all in conduit so it can be replaced or added to as necessary providing the friggin' moles don't get it. Was wondering if I can find one of the gas line subs, and see if they could trench and run a single no jointed line back. No idea what the difference in cost would be. Suppose I probably have to give sparky a junction box half way at least though. Opening through the woods would face west, so I can't get at the south winter exposure for passive solar. Too many trees that direction. Tall pines. Neighboring property might be a little peeved if I did some minor clear cutting on their property.:boxing: I was thinking along the lines of a coal/coke fired heater fed with auger on auto pilot, but after what Saum said about storage, unsure about that. Need further data. Nice thing about that is you could have split feeds and heat a shop off of it also using the same underslab underground radiant system, just in a different direction. Kahlil, correct in that, as trying to figure how to incorporate lower level for usage. |

from their brain to yours, no idea where you found that pic, but I didn't notice the trap doors when I was out there a few years back. The crazyhorse monument was pretty special. |

Re: Housing/Shelter talk:
Hey Scorp,
try going with hydronic baseboard heat, it's the cheapest operating cost. Only a pump to run or maybe several mini pumps (100 watt ea) or zone valves, you can parallel an LP boiler with a wood boiler for backup. Lennox pulse boilers are the best of the residential bunch. When I lived in Anchorage it was the best system. Andy's right about the a/c mini splits too, they also come in heat pump varity but the air to air heat pumps suck in wet northern climates. |
Re: Housing/Shelter talk:
Good thought Halo,
have a car wash with black tubing underslab (20 yr old), stuff rotting out and have to tear up the slabs to replace it all. Pex is supposed to last. Supposed to. Usually how the warranty goes, here is more pex to replace your failed, then you are on your own tearing up floors, etc. or developing a new system. |

Re: Housing/Shelter talk:
Check out living underground. Constant temperatures means little heat and no air conditioning. Many other benefits.

Re: Housing/Shelter talk:
Scorpio,
You should get as much thermal mass into your house as possible. You'll be more comfortable summer and winter. Probably most important in a cold climate. Must have plenty of foam insulation on the exterior and provide for thermal breaks wherever possible. Myself, I would prefer something like the concrete dome as suggested by Mone, and similar to NOOB. Concrete's the way to go. Can't think of anything much better, as long as it is insulated well. I am hoping someday to build an underground concrete dome |
Re: Housing/Shelter talk:
Do consider the monolithic dome. Best decision I ever made.
Course, should you run afoul of the authorities, it's a sure bet your house will be called the "compound." :-) |
Re: Housing/Shelter talk:

Problem with hydronic is you have to have a fairly high water temp, it really doesn't get cranking until you hit 150-160 degree water temps, and you need a lot of baseboard footage based on your building heat loss....plus you don't get that "mass" warmed. In slab heating uses a fairly low water temp.....like 100-110 range. The new PEX is 'supposed' to be great stuff.....been on the market now going on 30 years and I haven't heard of problems.....but like you say about the warranty....."here ya go buddy......here's ya another pile of the crap.....you figure out how to get it in your slab"...typical building materials warranty..ahahahahaaaaa I think I'd try it if I ever build another home, though. |
Re: Housing/Shelter talk:
Personal preference, I do appreciate earth bermed homes, but I couldn't do the underground thing. I do not have the hill to work with to create a earth berm house.
