changing wall type between phases best practice

[roscopeco2000]

I will try my best to explain this, we are working on a property with a gable end wall, the gable end wall is going to be coming part down and an extra story built on top. We have the existing property drawn up and the walls on an existing phase. Now i have come to draw the new construction what is the practice?

A) Draw up a new wall over the top of the existing wall but on a new construction phase from the base of the wall to the new level. The problem with this method is all the doors and windows which are staying are hosted on the existing wall construction.

B) Do i set a new level above the existing wall and then click into the wall profile and get the base line to match the outline of the gable wall, The problem with this method i will be left with a line where the new wall meets the old.

I would be interested to hear how others tackle the issue of part of the wall being on one phase and part of the wall being on a new phase. Thanks

So, in a nutshell, you are talking this?:

What's your question?

Yes exactly so is the red section and the pink section created as 2 different walls so they can be in different phases? My question was, is the best practice to do it they way you have with the green section started from the eaves or have the green section go down to the base so the 2 walls existing over the top of each other. I think its best to do as you have shown.thanks

Huh? The "green" represents the New Construction, which includes a Floor.  New Construction walls are supported by the floor and the New Construction floor is supported by the  existing walls.  Are you not building an upper level? Are you just raising the roof?  I'm a bit lost.

Yeah i am confused also forget about floors or roof, my issue is to do with walls only. A wall which is part existing and part new construction. I was asking what is the best way to do it but you pretty answered with your diagram.thanks

You can either split the existing walls horizontally and demolish the upper ones; or create an in place void under the new phase and use it to 'demolish' the existing walls.

@roscopeco2000 : Just swinging back around to this thread  and noticed it hadn't been solved. I thought is was. Sorry. What more do we need to do to get a solution credit?  What more information would you like us provide you with?  Let us know.  

Cheers.
