Northriver Posted March 31, 2017 Share Posted March 31, 2017 I never thought about this before but I recently had to change the ceiling height of the first floor of a multi unit complex and the party walls did not change in height. I had to select the air space between the walls to get them to the correct height. What type of room definition should be specified at the air space between party walls? Thanks.

ShaneK Posted March 31, 2017 Share Posted March 31, 2017 Maybe the floor above was stopping it or maybe define it as "Open below". Strip the plan file down and post it. Link to comment Share on other sites More sharing options...
Chopsaw Posted March 31, 2017 Share Posted March 31, 2017 I think the trick is to not have an air space or include it in the definition of one of the walls. You might also try making one of the walls a "Furred" wall. Link to comment Share on other sites More sharing options...
Northriver Posted March 31, 2017 Author Share Posted March 31, 2017 I am designing "fee simple" Town Homes. I have 2- 2x4 1 hour fire walls separating the units. The property lines run right down the middle of the 2 party walls so the party walls cannot touch each other and it helps with noise transmission from unit to unit.

Northriver Posted March 31, 2017 Author Share Posted March 31, 2017 So Eric your saying build it as one wall? That would work except the units are offset from each other. Would a room divider down the middle if the airspace and make the walls as no locate work? I realize I created a room when leaving an airspace. Like I said I fixed the problem but was wondering how to get the party walls to adjust with the room if I ever have to adjust the ceiling height again.

jorgearaya Posted March 31, 2017 Share Posted March 31, 2017 The two options are valid here. The way you drew it, leaving a space between two walls, if enclosed, they become a room, leave it unspecified and adjust its ceiling heights to match the other rooms. Wall type definitions as "Solver" showed also works and may be easier to work with. (However you had not mentioned they were offset). Link to comment Share on other sites More sharing options...
Northriver Posted March 31, 2017 Author Share Posted March 31, 2017 Yes Eric like that except I cannot have a common wall. The 2x6 wall you drew at the jog is the 2x4 parting wall at each unit. These are fee simple units. If these were condos I can do what you have drawn. Its the way the law is written in our state. We shy away from anything that is Condo due to lawsuits. PS: Thanks for your help. I have drawn many of these types of buildings but this is the first time I ever changed the ceiling height in this type structure.

NRST8TRKR Posted March 31, 2017 Share Posted March 31, 2017 Just completed a two unit building offset just like this. Have to use party wall as Eric, has, said and then Exterior wall for offset and run exterior wall of unit a past party wall on one side and exterior wall of unit b past party wall on other side. Makes for pain for dimensioning and things jumping around. Great week end to all,Ken Link to comment Share on other sites More sharing options...
justmejerry Posted April 1, 2017 Share Posted April 1, 2017 Northriver, could you post a pic of the jog as you have it drawn? Curious to see how it works there. Link to comment Share on other sites More sharing options...
