A 20-foot-wide Upper East Side townhouse is back on the market for $25 million.

It was first listed for $35 million in 2008, per StreetEasy.

The Neo-Georgian spread at 163 E. 64th St. — owned by commercial broker Kenneth Laub — was built in 1872 and re-clad in brick and limestone in 1902, according to the listing.

The home has five bedrooms, five bathrooms, three half-bathrooms — and a high-speed elevator.

Outdoor spaces include a courtyard and rear garden. The listing brokers are Oliver Brown and Caleb Loftus, of Compass.
