    Very nice with a really useful loft with headroom for a change!!

    And the deck is very cool literally with the breeze and great view. Not sure why more roof are not used like it, at least where snowloads are not bad.

    I also like Lamar’s requirement that they have their own power, water supply as that is the near future on power at least. Thankfully well done lean power, especially completely off grid cost so much less that utility power.

    Well done clean power costs under $.06/kwhr and gives a 20-50% return on investment for 20+ yrs. hard to get returns like that in any other investment, that is other than a well done TH.

    One of the best TH designs I’ve seen.

    Time for the curmudgeon to check in. Pros: Livable footprint compared to most THs, and a kitchen you could screen off. Interesting circa 1960s exterior. Cons: Once again, no “official” downstairs bedroom for those who can’t climb stairs. No porches or sufficient overhangs necessary for southern living (were those against LaMar’s rules?). JerryD, per your question, the heat from that deck would cook the bedroom during the day. Upper story decks incorporated into the house structure like that also eventually leak (usually sooner than later).

    The main thing this plan had going for it, and failed to utilize, was the possibility for a second bedroom or office upstairs. Forget the deck, which is aesthetic but a disaster waiting to happen, and continue the roofline across the entire house and create a second upstairs room. Then add the deck, creating a carport or much-needed shade, without being structurally integrated into the house. The house roof-line wouldn’t have the “chopped in half” look, and the house would really work for people with a child, or some of the crafters who would relish an extra room. You could still have the walk-out deck, without the problems. Would love to see some porches on those doors, too 🙂

    I really like the design and the incorporation of the off-grid solar. The upper level with full head room and stairs (I can’t do ladders) makes it much more liveable. I have to disagree with Sally in that if the home is maintained properly there shouldn’t be an issue of impending disaster to the upper level porch. This is a very well done plan and I would absolutely live in this one!!

    I love this house design, but would like to know cost estimates. I think all should incorporate solar and run off or re-cycling of water. Great Job!

      Yes definitely would be helpful to include cost estimates for building including the cost of all the equipment needed to make it off-the-grid.

    Very doable design, easy to move about inside. Love the rainwater retention system (smart design) and the connection to the outdoors through the open patio.

    Love this house, lots of space and the footprint is well within what I can build ( I want a secondary home on my property for me as I am aging and the big house can go to the kid and family) But, height is an issue where I need to build and that is very seldom included in a design.
