Live where Desiree Gruber and Kyle MacLachlan party

Who said Upper East Side backyards are hard to come by?

Only in New York does “semi-detached” mean two combined mansions.

Now that Karen and Matthew Gruber’s kids are getting older, the couple is downsizing to one townhouse and renting out the other. It’s more than 10,000 square feet asking $39,000 a month.

The double-wide townhouse, at 222 E. 83rd St., features six bedrooms, a large entrance foyer and a large backyard: a 1,200-square-foot garden reinforced with steel beams for privacy and decoration. Fabulous soirées have been held here for large organizations, …says Matthew’s sister, Full Picture founder and Project Runway exec producer Desiree Gruber, who has attended charity events here with her actor hubby Kyle MacLachlan.

There’s an outdoor BBQ, four basketball hoops and French doors that open to the outdoor space.

The home comes with a live-in caretaker/handyman/landscaper who is good with garbage disposal and firewood delivery as well.

The space works so well to host large events that it even comes with Karen’s secret back book outline for exactly how to entertain and make the most of the space, including directions on how to set up an impromptu party the same day with supplies, decoration and staffing.
