About This Property
Triple penthouse with private outdoor space! This unique four bedroom, three bathroom coop loft is available on the private market and ready for a lucky new owner.
A keyed elevator leads you to your semi-private landing, and onto the ground level of the apartment. On this floor are 11-foot ceilings, an enormous open loft space with powder room, southern-facing windows, an open, SieMatic vented chef's kitchen, an office, a den, and a separate dining area flanked in gorgeous built-ins. It truly screams Flatiron loft!
The second floor has two bedrooms and a full bathroom, as well as a full-sized laundry room and dog washing station.
The top level of this triplex is the primary suite, as well as private terrace. The bedroom is large, with en-suite bathroom inclusive of a double vanity, soaking tub, and stall shower. There is a large, built-out customized closet and access to an approximately 300 square foot irrigated private terrace.
There are three zones of air conditioning, two separate entrances, and a security system.
The cooperative comprises 21 residences over 8 stories and lies on the corner of 20th and Fifth. It has a full-time super, video intercom, keyed elevator, and separate laundry and bike storage. The building enjoys free and clear ownership (no mortgage) and a retail cooperative covers about 1/3 of the building's expenses.

Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Compass.
A keyed elevator opens onto a semi-private landing and straight into the ground level of this triplex at 131 Fifth Avenue, and that's what sets its layout apart. The home runs to 3,500 square feet across four bedrooms and three bathrooms.
The ground level has 11-foot ceilings and one open loft space with a powder room. Southern-facing windows run along it, and the SieMatic vented chef's kitchen sits inside that room alongside an office, a den and a separate dining area framed by built-ins. The built-ins are worth a close look in person.
On an open horizon, a south-facing window gets about 8.5 hours of direct sun around the winter solstice, from 7:41 AM to 4:07 PM, and about 10 hours around the equinoxes. Nearby buildings can block some of that.
The second floor has two bedrooms, a full bathroom, a full-sized laundry room and a dog washing station. The apartment also has a washer and dryer in the unit, three zones of central air conditioning and a security system.
The top level is the primary suite, which opens onto a private irrigated terrace of about 300 square feet. The en-suite bath has a double vanity, a soaking tub and a stall shower, and the bedroom's closet is built out to order.
The building has 21 residences over 8 stories, a full-time super, a video intercom, a keyed elevator, and separate laundry and bike storage. Cats and dogs are allowed. Madison Square Park and Union Square Park are each about 4 minutes on foot, and the 23 St station for the R and W trains is about 4 minutes away.
