You may not know her, but you definitely know her work.

Alice Ireys is the famed landscape architect behind the Brooklyn Botanical Garden, the Clark Botanic Garden, the Abigail Adams Smith Museum and the Brooklyn Museum.

Now her former townhouse is on the market — for $7.49 million.

Built in 1825, the renovated townhouse is at 45 Willow St. in Brooklyn — not far from Michelle Williams’ home on the same street.

Iryes lived in the townhouse her entire life, until her death at age 89 in 2000 and her family owned the house from the time it was built in 1835. 

At 25 feet wide, the four-story brick townhouse features five bedrooms, five bathrooms, a parlor room, chef’s kitchen and pine and oak floors. The main bedroom includes a den/library with a fireplace and ensuite bathroom.

Above the main bedroom is a corner office “with a ship’s bow-feel,” according to the listing. 

Outside, the landscaped, two-tiered garden designed by Ireys has won the American Society of Landscape Architects Design Merit Award.

The listing brokers are Ravi Kantha, Matthew Lesser, Gian Mitchell and Cameron LeCates of Leslie J. Garfield.

“It’s one of the nicest gardens and most charming houses in all of New York City,” Kantha says.
