This is a regular statement by people who think that physics somehow is something that they can avoid because it is their home. Like commercial movie theaters suddenly have white walls, beige carpet, and white ceilings... with large windows.
I mean this mostly in jest, but if you want to make a home theater using front projection, you need to deal with the ambient light in your room FIRST.
Getting a really good projector, like the Epson 5050, then putting it into a terrible room will give you terrible results. That's just reality.
You may have a viewable image, but contrast will be poor, and with a larger than typical screen size (161" is 77 square feet of screen space, vs. 120" which is 43 square feet), you will be needing every lumen the projector can deliver in as dark of a room as possible.
You can do front projection with some lights on, you can even have a so-so room, but it isn't ideal, and you have to accept that image quality will be limited to the quality of the room.
The two biggest improvements anyone can make to a room come from good blackout shades and a few gallons of dark paint on the walls and ceiling. That $500-$1,000 spent can make a $1,000 projector look better than a $3,000 projector in an untreated room.
