A roomy spread in Porter House, at 66 Ninth Ave. in the Meatpacking District, is about to hit the market for $29 million.

The 5,500-square-foot unit, newly created by design darling Paris Forino, spans the entire sixth floor. A combo of three separate units, it features five bedrooms, 6½ bathrooms and a private terrace.

Over-the-top custom metal details include a 200-pound “showstopper” of a front door and a 400-pound bronze kitchen sink. There’s also a wet bar in the den with two solid brass custom shelves and bleached walnut millwork. The building — itself a combo, with a 1905 structure topped by a 15,000-square-foot, off-angle zinc-and-glass addition — is eye-catching.

Past residents have included Olivia Wilde and Jason Sudeikis, who sold their two-bedroom nest for $3.8 million in 2015.

The listing broker is Nest Seekers International’s Jessica Campbell.
