Please review my plans...and pick holes in them :). I don't guarantee to change my mind, but I do promise to research varying opinions thoroughly and supporting data would be appreciated.

Please pick my plan apart- better now than after it's built.

If anyone wants to provide input it would be greatly appreciated.

This is to be our retirement home. Energy efficient, double stud walls, the walkout is to the south. Masonry wood stove in living room.

Please note the three level breezeway. I struggled with window sizing and ended up with a lot of different sizes based on room use not exterior balance. Not good?

The South First floor overhang is too small. My designer/draftsman changed it to give upstairs windows some room. That will change and go to 9' ceilings in upstairs if needed.

Suggestions for house plans

Hello again,

Moving on from the great heating advice that we recieved a while back from you guys on here, we're carrying on with the design of our new home. We're still working on a few details of the home plans. We have the shape of the house ironed down but may have to come back to rearrange some partitions inside.
I've spent the last while going through a lot of the articles and discussions on GBA. Some aspects of the house I now feel good about, and they been positively reinforced with the opinions on here.

Mixed roof insulation methods


We are building a home near Ann Arbor, MI and would like some advice on how to approach a specific portion of our building section.

The majority of the home will have R60 blown in cellulose (blue areas) with Intello Plus underneath. The vaulted (red) area will be R60 closed cell foam. The walls will be EIFS, 2x6 R20 Roxul with 4" EPS exterior foam.

Our concern is the clerestory wall (green and purple).
We will continue the EIFS on the exterior portion of the wall (green), but are a little unsure what to do on the vented ceiling/interior wall (purple) section.

I’m remodeling a roof constructed from tongue-and-groove cedar planks that serve as a cathedral ceiling

I'm re-modeling a roof (~1:4 slope) constructed from 2.75" x 6" cedar planks (tongue & groove) that serve as a cathedral ceiling, structural support, and roof sheathing. (In Climate zone 5.) I have a tentative plan of adding 7.5" of polyiso sheet and then a metal roof.

The part of the house this roof covers is 24' x 28'. The roof has 4.5' overhangs on the north and south sides. The only penetrations are 1 vent fan, a light tube, and vent for water heater.

Custom French trench drain design for specific soil & flooding

I live in rural CO and have a mix of silty fine dirt and clay in my yard. I get some standing water in this portion of my yard during Spring snow melt and flash rains. I also get some of this water (only 1" standing in 1/5 of area) minorly in my 50 year old, 4 foot high crawlspace. It travels under the footer which is about 48 inches deep and 10 feet away on the same side of the home where I have room to put the trench, same side the yard water stands.

Basement insulation with different slab levels

My proposed basement has 2 levels and I am trying to finalize the details to insulate where the 2 levels meet. I am planning on insulating the perimeter walls from the inside. However, where the floor levels change I am contemplating insulating under and around the footer, and then up the sides of the foundation wall to the top of each slab. The assembly from top down is 4" concrete, vapor barrier (not shown), 4" of EPS type IX, 4" of 1/2" clean stone, undisturbed earth. The footer is 30" wide x 12" and the foundation wall is 12" wide, standard size around here.

Who’s up for another house plan review?

Last time someone posted a house design, people seemed to enjoy critiquing it. If you enjoy doing that, here is another chance. If not, please ignore this thread.

I created this house plan with my in-laws in mind. We are trying to convince them to move closer to us near Flint, Michigan. If we can find a nice lakefront lot to build on and a good design, we might have a chance. They are retired. Stairs are not currently a problem for them, but the house is designed so that they wouldn't need to go to the second floor.

Best HVAC system and suggested improvements

My wife and I are seriously considering building a home on a large lot in a rural area near Rochester, NY (Zone 5). Our general plan is a single story house slab-on-grade house with a partially enclosed courtyard. It poses some challenges, because for its floor area, it has a large and long footprint. I've attached my rough plan for the house, with the hope that I can get some good insight from the GBA crowd.
