MiraBay two-story great rooms: block below the second-floor line, studs above it
MiraBay was built from the 2000s into the 2020s, and its two-story plans are block-frame, CBS on the first floor and wood frame on the second. The great room is where that shows, because plans that open it to the floor above give it a tall wall that changes material partway up. The block runs to about the second-floor line, 9 or 10 feet up, and the framing starts there. A TV at a sensible height lands on the block, which means a hammer drill, 1/4-inch Tapcons in the solid webs and the +$99 masonry surcharge. A tall wall tempts people to hang the screen high, but a two-story ceiling does not move anyone's eyes, so the installer holds screen center between 42 and 48 inches. Interior walls in these houses are wood stud, so a TV on the wall shared with the stair or the dining room is a lag-bolt job at the standard rate. Upstairs, a bedroom TV goes on framing at 42-50 inches to center. Tall glass brings glare, so a tilt bracket set a few degrees down earns its place. A MiraBay great-room install runs 60-90 minutes.
