Wall-Mounted Fold-Down Murphy Desk With Storage

We need a custom-built fold-down murphy desk installed against a wall in a spare bedroom that doubles as a home office. The desktop should be roughly 120cm wide by 55-60cm deep when unfolded, hinged along the back edge with a full-length piano hinge so it lays flat against the wall when not in use. Folding support brackets or gas struts should hold the desktop level when open and allow a smooth, controlled fold when closing, with a stop that prevents the desktop from slamming shut. The whole unit must anchor into wall studs — a french cleat or ledger strip screwed through the drywall into framing, rated for a laptop, monitor arm, and a stack of books resting on the open desktop. Above and to one side of the desk, build in open shelving and one or two small drawers or cubbies for stationery, cables, and a small printer, matching the depth of the folded desktop so nothing protrudes into the room when closed. Please route a channel or grommet through the back panel for power and network cables so a power strip can sit inside the cabinet rather than dangling loose. Materials should be paint-grade plywood or MDF finished to match the existing white baseboard and door trim already in the room — please show a paint sheen sample before committing to the full unit. We'd like the folding mechanism tested through at least twenty open-close cycles before the install is considered complete, and the clearance from the desktop's folded position to any door swing or light switch confirmed on site. Timeline is flexible but we'd like the whole build, from measuring to final install and touch-up paint, wrapped up within about two weeks.
