A house is such an individual thing that someone who uses a stock design is likely to be dissapointed. First, in a very detailed manor you need to decide exactly what you want in the house
There are a couple of ways to acomplish what you want. The first is to design it yourself. there are plenty of books on this subject. From my own experiance, expect to spend 6 months to a year to develop a plan that you like. Then find someone to produce a set of building plans from your design. this is the least expensive and requires the largest investment in your time. this is what I did. Before you deside on a plan, figure out what you need and want in the house. Don't think square feet, think things you want. Start with rooms, heating and ventalation needs, how you cook, number of ocupants, location of the septic system in relation to the house, how often you have guests, do you need shop space? a garage?
The more detailed you get with your needs, the better a house can fulfill those needs
Below was my initial thoughts for the house I wanted to build. by the time I got to building it I had changed my prioritys somewhat
House wish list for Eric Anderson
Size: at least 1000 ft^2 of interior space to meet current zoning regs in town.(does not include basement) likely a ranch with full basement optimized for a workshop
Themes for house:
Open floor plan well lit, sun tempered, well ventilated, simple, low cost, high quality. Universal design principals for space and door openings. Multifunctional, Minimalist theme. Green when practical, minimal tax assessment ease of maintenance.
Sections: Interior details, basement shop details, exterior details, construction details hvac, plumbing, Solar
Rooms will be 2 bedrooms, single bath, kitchen/ eating, entrance and living room, open functional basement
Interior details
Bedrooms
1 large bedroom at least 12X12 with lots of closet space
1 smaller guest bedroom with usable closet doubles as a home office.
Both will have ceiling mounted fluorescent lights Master bedroom will have ceiling fan and wall mounted AC ability to cool only one bedroom.
Wood floors
Entrance/ Mudroom
Entrance to house has place to set objects down
Bench for dressing, Closet for coats, shoes, etc easy access to kitchen. Lots of storage space

Quality cabinets light color, birch or oak Granite tile countertop wood edging with epoxy coating Likely 24” tiles or 25.5” tiles with no edging
Built in coffee maker superautomatic, moderate size microwave
I would like to preserve counter space by placing microwave in a wall mount with outlet behind it
Reasonable amount of pantry cabinet’s Well lit
Ceramic tile floor.
No formal dining space
Bathroom
Low maintenance
Sink and 36-48” vanity with large mirror
Shower unit swanstone or Porcelain base or tileready pan tile wall in corner with controls in interior wall 36X48-54” unit glass front unit
Good quiet exhaust fan with timer or humidity sensor central in bathroom I would use either Panasonic whisperlight unit with fluorescent light or Fantech exterior mount fan with FL light.
Tubular skylight 10-14”
Highest quality toilet available
Ceramic or granite Tile floor
Good sized casement window
Task lighting for sink
Living room
Natural light from southern windows
Wood floors
Variable lighting for reading and hanging out
Ceiling fan
Wood Stove centrally located along the wall with the bedroom designed to heat whole house.
Sized to accommodate 1 couch and 1 chair woven matt syle rug.
Space on wall to add television
Ability to all small dining room table for eating in larger groups
Room in basement that contains boiler, hot water tank, solar tank
Washer dryer, tub sink
Minimal doors; 2 exterior, 4 interior. Interior doors to bathroom will have translucent panel if possible
Interior 36” wide for universal design 2 for bedrooms, 1 bathroom one to basement . All doors will have lever handles.
Basement
Basement will have sheetrock walls to cover the polysteel foam walls.
The basement will include a high efficiency washer and propane dryer, oil burner and indirect water heater, As much as possible the plumbing, electrical and HRV will remain exposed for easy maintenance. The majority of the space will be utilized as a workshop. Eventual there will be a storage area walled off, but not in the initial building. The basement should have a walkout on the west side the (Not for cars) The ceiling will not be finished and the floor will remain bare concrete. Note: I don’t want to be assessed as having a finished basement. The way the rules are written, if any 2 of the 3 surfaces (ceiling, walls, floor) are finished it is considered as finished space per the assessment.
Basement floor. Consider using epoxy floor coating per Dave f. He and I would install it. Basement floor must be poured at least 1 month prior to epoxy encapsulation This must be done at a later date as it will change the assessment to finished basement.
Exterior
Outside will be oriented 192° Magnetic long axis for max solar gain. Clearing will be extensive to the south in a fan shape for max solar gain. I will take into account when the leaves are off trees relative to how much I clear. Max exposure from 10-3 I will use solar pathfinder to determine clearing levels. Absolute minimum clearing on the other 3 sides. To preserve shading. Consult Tyler Thompkins re landscape architecture. House to blend in with surroundings think earth tones. There will be no lawn. Anticipate low ground cover over septic and south exposure area.
Main entrance to house off of south side. Short walkway to driveway. Potential for a ramp to front door.
Drive way gravel large enough turnaround to accommodate emergency vehicles
K turn acceptable. Not available max vehicle of fire dept =________
Overhangs will be 24” all around
Small porch on the north side at ground level. Space should accommodate 42” round table and chairs. Separate spot for Adirondack chairs. could be patio also. Room for outdoor kitchen and outdoor shower (phase 2 of building process) Chin up bar and room for stretching and sit-ups desirable.
HVAC
Heating
Oil furnace with baseboard heating. I want efficient unit with outside air supply. Mark Marzialo will do heat balance calcs and order and install system with me Radiators will be on main floor and will use copper stubbs into basement. The main runs of tubing will be Pex-Al pex probably ¾”
2 zones on main floor(bedrooms, and remaining space). In basement 1 zone with a fan type radiator for occasional use, one zone for indirect very small hot water tank Programable thermostat, outside temp reset
Consider Propane?
Metal chimney through chase
Wood Stove centrally located along the wall with the bedroom designed to heat whole house. I am going to install one the Doreen is giving me
Passive solar, south wall will contain ~ 80 ft^2 glass. Minimal glass on East, West and North faces. High solar gain glass on south side, Highly insulated glass on other 3 sides Kohltech would be my first choice.
Recirculation type Solarsheat 1500 g 2 pack solar airheater with the heat directed into the basement
Ventilation
Windows on all 4 sides of the house are casement, openable to provide cross flow in any breeze
HRV Air exchanger with heat exchanger for air quality. Located in basement draws from bathroom and kitchen exhausts into bedrooms. Should the exhaust and fresh air supply be located on north or south side? south I think. Must have defrost mode. Must also have a good programmable capability
Bathroom has a 150 cfm capacity vent fan quiet
Kitchen stove has a vent 3-400 cfm quiet
Whole house fan in center of house ceiling 1000 cfm R38 unit low power draw summer use only
House should have pressure balance air supply when woodstove is operating. Consider room to room vents for pressure equalization. Must be closable for summer bedroom AC
AC in bedroom only
Should I install a dehumidifier in the basement?
Plumbing
Supply side
Well by Stavins brothers including pressure tank and installation.
Plumbing and hot water and solar tanks are centralized in basement directly under kitchen and bathroom.
Distribution system will be Manblock home run system with a combination of 3/8 and ½ inch pex tubing. The tubing runs can all be kept down to 10 ft or less. The lines will be run exposed and utilize the utility chase as much as possible to make maintenance easy. There will be no tubing splices The water lines will be as follows:
Cold: 11 total kitchen (sink, refrigerator, possibly coffeemaker) Bathroom (Sink, Toilet, shower) Basement (Sink, washing machine) Outside South, and north sides of house, one on north side to outside shower.
Hot 7 total kitchen (sink, dishwasher) Bathroom (Sink, shower) Basement (Sink, washing machine) Outside north sides of house to outside shower.
I will leave a few open slots for additional lines down the road
Drain waste vent
ABS tubing
I want to use a single vent/waste stack up through the utility chase. The biggest difficulty I see is the shower drain is directly under the stairway base. Because I am using 9 ft ceilings, it should be ok clearance wise. I will need a plumber to do the layout for this. Will get the septic offsets from mike turner. I want a clean out in the basement placed so an additional bathroom could be installed in the basement at a later date.
Solar domestic hot water
I am anticipating using AET’s indirect IPV system pressurized glycol loop solar system. This is the simplest system using a PV array to power the pump. I think I want the 40 ft^2 collector area and 80 gallon tank. System will be installed in series with a small indirect tank warmed by one zone of the boiler. Include anti scald tempering valve
Alternatively I might go for a small propane tankless hot water heater System will be installed with double isolation valves so hot water can come directly from the solar tank in the summer, but the indirect tank can be used as a stand alone if the solar system has problems. Peter Ashly will do the install if I have problems. I will run all copper tubing to the collector on the roof due to possible very high temperatures
Foundation
Assumptions 2 story building light frame construction
Walls are 40 ft X 28 ft OD. 136 linear ft
Assume soils are 2000 lbs per ft^2 ask Mike Turner again for insight on this.
Footing table 403-1 width =12” height =8”
Mix for footings and walls 3000 psi 96.75$ yard need 8 yards footings
Reference 402-2
Footings must be below frost line =42”
Foundation wall assume 9’ wall 7’ unbalanced backfill height
Table 404.1.1(2)
Need 8” nominal wall thickness
Vertical reinforcement #6 32” OC
The goal will be to use poly steel ICF forms. This gives me R20 walls for the basement. I would use Polysteel’s reinforcement schedule. Polysteel references costs on square ft of wall installed at 10$ ft^2 nominal Estimate from polysteelnortheast.com is including footings,
Waterproofing is 0.90$ ft^2 assuming Tough and dry application. Probably will get Dave Fortier to spray it ~$0.45 ft^2. Suggested alternative is a peal and stick 0.040 thick membrane. Same 0.90$ ft^2 cost.
The parts that are exposed above grade need to have the foam covered. Suggestion is to use synthetic stucco system 2.50 ft^2$ installed.
If I use insulated concrete forms applicable reg is 404.4.1
Need to meet provisions of aci 318
Foundation drainage shall be provided and shall drain to daylight.
Underneath the basement floor will be 4-6” gravel, then 2” formular extruded Styrofoam insulation then 4” 3500 psi concrete.
There will be one floor drain near the boiler and water heater.
There will be footing for 3 piers on centerline of the long axis located 10’ OC. These carry only the load from the first floor, No loading from ceiling is transmitted
First floor=28X40 = 1120 ft^2 times 60 lbs/ft^2 20 lbs dead and 40 lbs live
67,200 lbs total load of first floor ½ of this is supported by the center beam
33,300 lbs
with 3 center columns there is a total of 5 support points = 6,700 lbs per column
Since the load bearing capability of the soil is 2000 lbs ft^2, you need 3.35 ft^2
Make the column supports 24X24”
I want the basement to have a walkout door on the west side. This implies the grading shall accommodate this. The door shall be a 48”-72” wide single or double French door to accommodate woodworking machinery entrance Definitely no garage door.
I would like a reasonable window ~ 4X4ft on west side Possibly several window on south side
Specifications for framing
Ground floor
I intend to use Ijoists for flooring over a center beam
Center beam lvl built up beam 5 ¼ X11 ¼
28 ft span
40 lbs live load
20 lbs dead load
everything is designed to l/480 deflection so there is no issue with tile/ etc
I will use 3 laly columns which yields a column spacing of 10’ (span)
Using span tables from Ilevel true joist for floor girder beams
40lbs ll 20 lbs dl 28’ span 3 ½ X11 ¼ lvl beam gives l/360 deflection
I am increasing it by 1.5X to get to L/480 deflection
Main center floor girder will be 5 ¼ X 11 ¼ Dropped beam. Actually it will be 3 sections of 1 ¾ X 11 ¼ LVL
Floor joists will be trujoist tji210 9 ½” depth 16” oc 28 ft long
Joist will be doubled under wall spanning the whole floor
For subfloor I can use 7/8 OSB with no issues. It will be glued and nailed
I will use the rim joist material and joist sections to carry the loads from the walls and roof loads.
Walls
2X6 construction using 92”studs 24” OC for the 40 ft long walls.
If it is cost effective I will use EL top and bottom plates so they are continuous pieces.
Build corners using 3 stud warm corner usning formular insulation
For the 28’ walls I will use 2X6 92.5” studs
Standard double top plate
Basic wall section should be drywall, studs and fiberglass insulation, exterior osb or plywood sheathing 3/8 or 1/2” with 1” polyisocyanate insulation with seems taped, then 15lb roofing felt for the water drainage plane then mesh and finally vertical wood siding shiplap eastern white pine barn siding with both sides stained prior to installation
For the interior partitions I will use 2X4 construction 24” OC
The roof will formed using trusses I will use a basic scissor truss 24” OC. I would like 5/12 roof and 2/12 ceiling pitch. The overall span will be 28’ with a 2 ft overhang on each side. I would like to use a gable truss for the roof over the bedrooms.
At the ends I would like to use a dropped gable end truss so I can add outlookers and have a 24” roof overhang on the ends. What are the truss manufacturer’s recommendations for this? My plan is to minimize labor involved in installing the trusses. I will need the truss manufacturers truss bracing schedule.
Because these are scissor trusses special considerations will be necessary to deal with flex. I do not know how much of a problem it will be with the trusses I am selecting.
I am assuming I will use the simpson movable truss connector on one end. Probably the end on the south side (no interior wall connections on the out side for flex to be a problem.
So to summarize the truss specs, I need:
Quantity 19
Clear span 28’ 0”
Overhang 2’ 0”
Pitch 5/12
Ceiling pitch 2/12
8” energy heel
ends plumb cut
Quantity 7 gable trusses same pitch overhang and energy heel
Quantity 2
Dropped end gable trusses (not scissor) that will accommodate 2X6 outlookers
Roof
Roof will be asphalt shingles 50 year architectural shingles. Over 30 lb felt. I will use 2 layers of water and ice dam ~ 6 ft of coverage to be safe. I will buy the starter shingle pack and roof vent at the same time. The sides will have cedar shingles angles to keep water from dripping of the sides. John Shean will order the stuff for me on his account
The following will be openings in the roof:
1 plumbing vent 4” ABS on north side
(2) 6-8” Metal chimney vents that will extend 3+ ft above roof. One will be located in the service chase on the north side backing up to the kitchen. One will be on the south side central along the bedroom wall (for the wood stove)
2 sun tunnels on the north side one above the kitchen one parallel to bathroom These will both be on 24” risers which should give them enough clearance to get direct sun even in the winter As an option, can I exit the sun tunnels on the south roof and just make a sharper bend to get to the opening in the ceiling?
One opening for the solar domestic water heater lines.
4- attachment points for the solar panel
Windows and exterior doors
I would like the windows on the south side to be double pane Pyrolytic loE with argon with a high solar Gain Kohltech “Solarglass” is my first choice. The other 3 sides can be argon or krypton filled double or triple pane with soft coat LoE coating on both panes. Kohltech “energlass” would be good. All windows will be Casements. The only 2 that will be fixed will be the center window of the triples on the south side
Both entrance doors on the ground floor will be insulated single lite glass doors. The basement door can be industrial type but well insulated. All doors will have lever handles
Front entrance and Basement doors will have keypad locks to eliminate door key See Paul Brazau for the door locks
Electrical and lighting
see spreadsheet All lights fluorescent where possible
Multimedia and house Automation
The Wall outside the bathroom should contain all the house automation stuff
This includes thermostat for main floor, HRV control, ceiling fan, whole house fan
I would like in wall speakers in kitchen living, room, bedroom and on the north side exterior with individual sound controls.
Cable hookup wall jack in living room
Multi media cable to both bedrooms, kitchen and living room. Main junction and panel will be in the basement
Insulation details
Basement floor R 8 2” ridged foam insulation
Basement walls R 20 ICF construction
First floor walls Drywall- R 19 fiberglass insulation + sheithing1” polyisocyanate exterior sheathing over OSB ~ R25 with minimal thermal bridging Airtight drywall insulation
Windows R 3-4 (solar gain depending on orientation)
Ceiling Minimal penetrations carefully sealed drywall then 1” polyisocyanate then R 30 fiberglass bats. Blow in additional fiberglass or cellulose insulation to make it R50
All ducts will be in basement or in walls conditioned space and will be min R4.
did I miss anything?
