Tri-Level Home, Stair well

[builtright3]

Hey Guy's

 

I'm trying to create this stairwell and these different elevations for it and I’m stuck. I can’t explain it so I’m sending some pictures and the plan is attached.

Any help would be appreciated, that you.Stairwell Plan.zip

Wow, I’m surprised this got 103 views with no response. I’m guessing because this is not easy to do. I’m thinking even with the most skilled person in Chief this would have to take a little time to build this area out with the stairwell and get all the finishes right.

I get it, there is a lot going on here and it’s a challenge to anyone.

Have a look at this it might get you moving in the right direction maybe, i had to use some polyline solids and a sofit to make it look better witch maybe no good for working drawings.

One more thing i don't think your landing is not the write height looking at photos

Is this close to what you are looking for?

 

 

Or this?

 

 

I don't understand where the problem lies with what you are trying to do.  Nor do I understand what the problem is with the exterior view of the floor supported by a column in one corner.

 

Could you talk about each area of problem?

I don't agree with the choices you made, but I think I understand why.  To address what you have drawn, first, I extended your basement walls to under the stairs.  Changed those outside walls to pony walls with rail top to header and post only on the corner.  Added a floor in that room with grass as the covering.  Showing floor at -28" temporarily.

Then I selected these two walls.

And lower the bottom in the stairwell to match the rest of the wall.

Then I went to your stairwell and lower the tops of the same wall portions inside the stairwell

This eliminates those walls in the stairwell, placing them below the stairwell floor so that you can still see stucco outside.

Your gaps between top of lower stair and landing, and the one between raised foyer floor and rest of home are due to how you chose to build the home.

 

I personally would have built the stairwell shaft level with first floor w/ balloon walls and used a stair landing.  Then dealt with that outside portion of the stairwell a little differently, but to achieve the same results.

1. There's a post in the picture you provided.  Remember that's when you couldn't explain it so you provided pictures to say it for you.

 

2. The code required backspan to cantilever span ratio is 2:1.  This means you need 8' of joist inside the home to cantilever 4' (for example.)

 

3. Your cantilever ends have roof load additionally on them as well.

 

Good luck.
