If you cook, get an honest to god hood vent. Installing one down the road is a biotch. If you have a high roof, deck the crap out of your attic space. That is a huge perk for storing stuff you only use occasionally like xmas trees and luggage. I have about 300 sqft of floor space in my attic and it is amazing. Now, it gets hot and cold but that's ok. Put lights up there with a couple of outlets.

Make decisions on things like windows, doors, fixtures etc in advance of when you think you'll need them.

Congrats on the house and your upcoming admittance to the nut house

I am just getting started on planning a new home. What are you guys seeing price wise for per living sq ft or per total under beam?

Site Work: It is always recommended to have your building pad bored to determine the bearing capacity of your soil. If soils are found to be adequate then make sure you have proper drainage away from your foundation, all organic matter is removed, and begin work. If the soil is not desirable, follow geotechnical recommendations for undercutting and refilling. A good rule of thumb if you don't have a soil bore done but are skeptical of the soil is to undercut 3x the thickness of your footing design and refill in 6" lifts compacting as you go. Insure proper drainage from your foundation and you are ready to dig footings.

Foundations: There are many types, monolithic, block and fill, and conventional are the most common. My preferred design is block and fill which allows me to elevate the slab higher with less forming. I recommend your finish floor to be a minimum of 12" above the sub grade. This allows for raised flower beds without the threat of water getting into your house. If you choose to build 4-6" above sub grade then install raised beds you are very likely to have issues with water down the road. I elevate all my homes to 20" for finish floor of heated space, with porches and garages being 7" lower with fall built into porches and garages to allow for drainage of water. Exterior footings should be under the entire perimeter of the home as well as all sides of porches, garages, and should run continuous with no breaks. Footing design varies for different soil types and load bearing requirements, but a minimum of 18" wide and 12" deep with 3-#4 bars is highly recommended. Grade beams under load bearing walls are also highly recommended and should be at minimum 8" wide x 8" deep with 2 #4 bars. I use a footing design of 20" wide x 14" deep with 4-#4 bars, three at the bottom and one at the top tied to the grade pin with 12" wide x 8" deep grade beams for single story homes, and increase to 24"x16" footings with 12"x12" grade beams for two story homes. If doing monolithic, tie one additional #4 bar to the bottom of your mudsill anchors, and if doing a block and fill install uprights out of footings every 32" and lay a bond beam course every other course with 1-#4 bar tie continuous as well as tieing 1-#4 bar at the top connected to your mudsill anchors. Mudsill anchors or anchor bolts should be installed 2' or less from all corners and exterior door openings as well as every 6' in between. Welded wire mesh is recommended, 10 gauge minimum. I use 6 gauge. Support all wire mesh to insure proper coverage of concrete and also make sure to overlap it at least 6" and tie it all together. Insure proper coverage of rebar in footings as well. Rebar should have 3" coverage minimum and should be located in the bottom 1/3 and top 1/3 of the footings, not the center. Rebar should have a minimum overlap of 20 x the diameter of the bar used and all corners should have corner bars lapping 24" each way or bends should run continuous through corners. No crossing and tieing intersections should be done. I recommend using Hercules #928 chairs for exterior footings, #924 for grade beams, and #911 under wire. 5-#4 bars should be tied diagonally to the wire mesh starting 6" from all inside corners and being spaced every 6". It is also a good idea to do this around tub boxes. I'm tired of typing, I'm going to continue a little each day until I make it all the way through the process.

If you're in an area that experiences frequent power outages now's the time to wire in a transfer switch, even if it's to run a few skeletal circuits off a portable unit.

If it were me, I'd upgrade the ceilings to make them use 5/8's inch drywall and request all screws. The sheetrock industry has cheapened the composition of drywall into a lightweight prodcut and the jury is still out as to it's long-term strength (will it sag between 2x4s over time).

After it's framed make sure there are 2x4's to screw to around all perimeters unless it's within a couple inches of a corner or you'll develope hairline cracks where the backing is lacking.

Don't cheap out on the windows, insulation or paint or you'll be redoing them sooner than later.

After the subfloor is down check the seams for any pooching, particularly where the two 4 foot sides butt together. It'lll stick out like a sore thumb if it's not reasonably level. Unless the high seams are sanded down they'll show through carpet and yard goods. You might get by with a hardwood floor.

I would also request fiberglass drywall around untiled shower or bath areas. Water resistant drywall (purple in color) is not waterproof and will still deteriorate over time.

If this house has a finishable basement, if you think ahead and try to consolodate electrical, plumbing and duct work into specific runs you could concievably only build the walls and paint the undrywalled ceiling black or dark blue. I've seen this done in theater rooms and it looks incredible.

Hope your project goes well.

Our guy puts our allowance in thru a local business and the business puts together a template of different fixtures to pick from. You can mix and match to your liking. Makes it MUCH easier than picking shite out of a 400 pg book. Also i read our carport dim wrong. Its a 22' x 24' carport

Fiancée and her mom went and picked out plumbing fixtures while I was in Nashville for a bachelor party this weekend. We went over them last night and made a few minor changes in sinks, but other than that, we're on the same page. Came in $600 under allowances light fixtures are next. I'm glad your garage isn't 12' wide
