If your walls could talk, what would they say? What if I said your walls already have their own language? It is written on the studs and posts behind your drywall, paneling, and layers of paint.
Numbers, written on boards because they are there to stay, and they are much easier to keep up with than paper. But it is not just measurements, sometimes there are special notes for the next contractor, things to be aware. Trinkets like pennies are left on some boards to act as a timestamp for future renovators to find. A common practice in construction.
If your walls could talk; I wonder what they already say.
