Real-world Application - A House of Giants
Framing and finishing a home with 36" x 80" interior doors for a family of 6'6" plus people, all over 260 lbs., required careful consideration. We had to meet and exceed building codes for railings and other support structures. One boy was an impressive 6'11" and 340 lbs., posing a unique challenge. He tended to use railings, towel bars, and toilet paper holders as support, causing wear and tear. To address this, we raised cabinets and countertops by 6" to accommodate the family's height.
Anticipating such challenges, we referred to this home as the "House of Giants." Despite the unique situation, the family remained pleasant and well-behaved. From time to time, we see the boys around the area and remember the challenges we faced in creating a functional and safe environment for them.
Understanding and incorporating these custom dimensions early in the planning stages can significantly enhance the longevity and functionality of your project.
