Alexander Development Group recently received approval on the site plan resolution for 140 East Prospect Avenue, a 21-story mixed-use tower in Mount Vernon, Westchester County. Perkins Eastman is responsible for the design of the transit-oriented construction, located one block north from the Mount Vernon East train station. Components of the 302,000-square-foot development include 350 rental units, 6,200 square feet of retail space with street frontage, and a garage with 226 parking spaces.
The approval by the planning board on June 4 was preceded by a city council approval in February 2025. The project is part of the Downtown Vision Plan, which was adopted by the City Council in January 2024 with the aim of revitalizing the downtown and updating zoning. Alexander Development Group is also responsible for the 42 Broad Fleetwood development in Mount Vernon, a 16-story, Passive House tower with 249 units that is more than 90 percent leased.

I like it.
Great job MV.
Curious how this one firm seems to have developed nearly all of the new buildings in Mount Vernon, NY. The Horizon was originally condo or cooperative but failed and converted to rentals. Is looks as if Mount Vernon is putting a lot of eggs into this one basket. I wonder why?
It definitely stands out from all the other white boxes.
All this talk of “revisioning” is about density. Density is always the real issue in all real estate development in the US.
Why haven’t I heard anything about this revision and why does it seem hard to find online? Besides that, that’s an interesting spot to put a 21 story building… don’t you think?
Right next to a train station makes perfect sense
Thank you urban developers. Urban growth is good. Growth in natural areas and farm areas is horrible.
I like it.
downtown Brooklyn , Jamaica, LIC developers take note!
Nothing in this neighborhood is taller than 4 stories. Maybe they should re-think this.
I’m seeing 8 stories a block away and 22 stories two blocks away. what are you smoking glenn?
