I just finished a working design for a 2100sq ft rancher around the 8'x15'x26' LR/HT. I'm going to try for vaulted throughout with 9' flat ceiling in the LR but I already know this is pushing the engineering available to me.
We loose the kids family room but their bedrooms nearly double in size.
The wife gets her own ensuite and walk in closet and I was able to add a half bath in the utilty room/family entrance.
3.5 bath, 3 bed.
Will start the scaled drawing tomorrow to see how close my line drawing is.
Inching closer to regular HT usage...
