I am attempting to self-teach HDP while designing the complete remodel of our own home. I don't want to cut corners in what I'm learning just to make it 'look' a certain way on screen. My goal is to be as accurate as possible where I can deliver the plans to our contractor without a lot of confusion or missing pieces/questions... I think I've done okay so far but now I'm completely stumped and need help/advise.
We have a ranch side split house ( previously added master suite is 4 steps up from main level and over the single car garage, which is 11 steps down from the main level). Our house also sits atop a sloping hill with a valley drop-off along the side of our property line. Part of the remodel will be adding an in-law apartment over the detached garage. All of that has been complicated enough to learn, but now I am stumped on how to add the bedroom loft in the garage apartment. Everything I have read/watched/researched tells me to either alter the foundation or to add another floor level - both of which alter the main house in the plans and jacks that all up.
In the apartment, I created the bathroom that will be under the loft for it to rest on...but the walls of the bathroom go all the way up to the gabled ceiling. If I lower the bathroom walls then it lowers the exterior wall as well. If I try to add a ceiling to the bathroom and main living area in order to create a second floor level to be the bedroom loft - making it open below over the main living area - then the added floor lowers the walls and ceiling of the main house to that same height as well.
All of my measurements have been gathered from our actual house and I've remeasured multiple times in various ways to be as accurate as possible. For the garage and apartment the measurements are:
Basement/Garage Stem Wall: 108"; (Absolute Elevations: Floor Above: 0"; Ceiling: -12 5/8"; Floor: -108"); Rough Ceiling: 95 3/8"; Basement/Garage Finished Ceiling: 95 3/8"; Apartment: Stem Wall: 108"; (Absolute Elevations: Ceiling: 168 1/8"; Floor: 0"; Floor Below: -108"); (Bathroom/Under Loft) Finished Ceiling: 116 1/2"; (Bathroom/Under Loft) Rough Ceiling: 118"; (Main Living Area: Open to Gable Roof) Finished Ceiling: 166 5/8"; (Main Living Area: Open to Gable Roof) Rough Ceiling: 168 1/8"
I have exhausted all the resources I have access to trying to figure out how to add this loft without altering the rest of the plans. I'm hoping someone with more experience/knowledge than me will have the magic answers that I'm missing and can help me. I do want to learn and figure out where I'm going wrong or what I'm missing here...so I've included a screenshot.
Please Help...and TIA!!
