ChrisCMCParticipantFirst off I want to create houses with 9 foot walls. Exterior walls made with 2×6 and interior walls 2×4 plumbing walls will have 2×6. I want the plans to be versatile, so the customer may have the option to easily take my plans and choose brick, vinyl, stone, stucco, etc. I would prefer that my demo renderings show brick, but what I’m struggling with is once the wall is built in the program and you want to change it, you got to tear it down and rebuild it, so I’m guessing I should not build with the 2×6 Brick Wall option? Which option should I choose?

2 in. x 6 in. x 104-5/8 in. Prime Whitewood Stud
So to make a 9 foot ceiling and using that product, if it is correct, is it as easy as changing this 8 to a 9 to make the plans correct in the program?
April 2, 2023 at 6:56 pm #16168ChrisCMCParticipantCrawl Space Foundation. I wish to design houses on this foundation for the reason that if the customer wanted a slab or a basement their contractor/builder could easily modify the home even easily adjusting the crawlspace height, I would use 48 in. height on my plan because foundation cinder blocks are 12-in W x 8-in H x 16-in L (correct?) Google tells me best practice is crawl space should be 44 to 48 height, 48 divided by eight in. height equals six. So six cinder blocks tall equals 48. But, here’s where I get confused, there is a mortar gap s of 3/8 inch. So measuring in 8 in. blocks height with mortar gap to get the height around an extra two inches taller throwing off the measurements. Five cinder blocks tall, five times eight equals 40, plus around an extra two inches for mortar would put it around 42.
So what’s a good crawl space height that is going to help customers and builders? I’m really confused on this.

I want the brick ledge at the footer. This is so the customer can choose, maybe they want vinyl for now, and years later redo and add brick or stone, or just do the outer now with brick or stone.
April 2, 2023 at 7:11 pm #16170ChrisCMCParticipantWall tools are giving me headache.
In this example, (left) a 2×4 brick wall and (Right) 2×6 brick wall.
April 2, 2023 at 7:12 pm #16172ChrisCMCParticipantAgain, framing option
April 2, 2023 at 7:14 pm #16174ChrisCMCParticipantI decide to change the boxed walls on the Left and make them 2×6 by editing the parameters.
April 2, 2023 at 7:15 pm #16176ChrisCMCParticipantGreat, they look thicker and the parameters are updated.
April 2, 2023 at 7:17 pm #16178ChrisCMCParticipantNow lets check the framing, nope, sorry they still show 2×4. So I guess if I need to change a wall the only thing I can do to make sure it’s right is to delete it and redo it correct?
April 2, 2023 at 7:28 pm #16180ChrisCMCParticipantLets say I’m building a dog house, and I am using a single sheet of 4×8 plywood as the floor. It’s a good dog house, a brick one. These values I’ve circled in red are showing the outside brick to brick measurements, I need the floor plywood measurements that I struck a red line on. So knowing a larger structure, the floor is going to be composed of several sheets of 4×8 plywood figuring out the dimensions of the structure is stressing me.

Yes a typical 9′ wall is 9’1 1/8″ high wall

That will only change the wall thickness it’s not changing the framing.

I wouldn’t over think this, just make sure you have the code required minimum distance of clearance below the beam or joists if your clear spanning them.

jkzimmParticipantTwo minor corrections, Blocks are made from Concrete, cinder blocks were made after WWII because of shortage of concrete so they mixed in Coal Cinders.
Most people use manufactured stones, even brick, that require no ledge. Just butter the backs and stick them to base coat with built in drainage. I would suggest you not try to allow for future real stone as it requires 12″ block to grade and then 8″ at ledge. A relatively expensive option , when manufactured stones are more common and require no ledge.
All dimensions of a Concrete Block are 3/8″ smaller than the nominal dimensions. So at 8″ high, all block end up at 48″ for 6 courses , which includes the mortar joint. This also applies to the 16″ length, mortar joint + block. 15 5/8″ + 3/8″ = 16″

April 16, 2023 at 5:13 pm #16224ChrisCMCParticipantThanks for your replies conwe and jkzimm
I’ve read your posts and did deep thought, googling for information and digging into the program. I hope I have something that would work now. Please check my work and tell me if this is workable. The idea is to design and sell house plans with crawl space. This is so the buyer could easily have a house with working crawlspace, or easily convert to basement or simply throw it on a slab. I’m assuming the crawlspace design is the harder to design but more flexible/versatile design for builders and buyers. I decided to go with 2×6 Vinyl Siding outer walls after reading jkzimm’s reply. Also designing with 2×4 interior walls and 2×6 interior on plumbing walls. — 1′ X 2′ Rect. Solid Strip Footing. — 8″ Concrete Block Wall – for foundation crawlspace wall. Please inspect the building Elements screenshot and Building Locations screenshot and let me know if these are acceptable working solutions for what I’m trying to do. Thanks in advance.
April 16, 2023 at 5:25 pm #16228ChrisCMCParticipantSo, when designing rooms and houses, floor plans inside numbers are the ones I need to make even if I can right? Not so much worry about the outer? Please see the attached image and pretend it’s a small building to keep some garden tools in or something, It’s just an example. Just saying when people look at the floor plan they would rather see rooms in dimensions of even numbers, for example 10×12 bedroom – 12×15 media room.. etc.
