No one wants to buy this famous interior design family's apartment -- which just got a $9 million price chop

Novogratz housestreeteasy.comHeidi Klum rented the apartment over the summer.

This luxurious townhouse overlooking the Hudson River just had its third price chop after six years on the market.

Owners Bob and Cortney Novogratz, a famous husband-and-wife interior design team, first listed the home in 2009 for $US25 million. The price has dropped several times and is now down to $US15.95 million.

Supermodel Heidi Klum rented the West Village spread over the summer, but now it’s empty again. Steven Gold of Town Residential holds the listing.

Welcome to the Novogratz's 7,180-square-foot townhouse. Watch your step in the mosaic entry hall.

After a long day, feel free to take the eight-person elevator from your private garage to your room.

The sparkling chandelier adds elegance to the spacious open kitchen.

A glass garage door extends the length of the living room during fair weather.

All five oversize bedrooms promise views of the Hudson River and Hoboken skyline.

Both the fourth and fifth floor have two bedrooms each.

Bob and Cortney have seven children, hence the name of their 2009 reality show, '9 by Design,' which aired on Bravo TV.

Today, the couple has a show on HGTV, called 'Home by Novogratz.' Here's a peek at their luxurious master bathroom.

The first floor basketball court transforms into a home theatre.

And a rooftop terrace has a full kitchen with a wood-burning pizza oven and grill.

There's also an adult playground with a TV, fireplace, hot tub, wine cooler, and beer tap.

Currently, the Novogratz's are renovating a 1920s era castle on the west coast, which perhaps explains their urgency to unload this gorgeous West Village apartment.
