We understand where [John Clarke Mills] is coming from when he says he wants a home theater but not at the expense of dedicating a room to it. His situation is a bit more sticky than most folks in that he has a beautifully kept Victorian era home. Recently he was removing a renovation from ages past that didn’t fit with the style and it gave him the opportunity to build in this hidden projector screen.
Years ago someone walled in this opening and added french doors. After opening up the wall [John] sized up the situation and decided he had just enough room to build a soffit which could hide a rolled up projection surface. He purchased a motorized screen (we’ve seen a few diy projection screens but can’t remember one that rolls up) and built a slot into the design just large enough for the screen to pass through. He’s testing it out in the clip after the break before doing the plaster work.
The columns on either side are his additions as well. The floor of the house is unlevel and one of those columns ended up a full inch longer than the other. We certainly can’t tell.
