My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
I love the idea of hiding components this way. This could work in the family room downstairs in the fireplace chase depending on where the chimney flue exits. You could then hide the screened panel with a slightly off-set picture or painting. (leaving room for ventilation.
Nice; i wonder though if the theater volume wouldn't kill the fish.
