What happened
A late-19th-century rowhouse at 427 E. 140th Street in Mott Haven, the Bronx, has been redeveloped as The William, a condominium project with 10 residences. The Bronx Daily reported the story on October 16, 2026. According to the project's website, about half of the building keeps the historic framework and the rest is a modern addition.
The building sits in the Mott Haven East Historic District. New York City Landmarks Preservation Commission records describe it as a Romanesque Revival / Renaissance Revival-style rowhouse designed by architect Walter H. C. Hornum and built between 1897 and 1900. In May 2023, the commission reviewed an application for rear-yard and rooftop additions, a connecting building on part of the lot, and excavation in part of the rear yard. It approved the application with modifications.
The units are not yet for sale. The project's website says its offering plan has been submitted to the New York State Attorney General's Office but has not been accepted for filing. The website says units cannot be offered or sold until it is accepted. The website also mentions financing programs that may be available to qualified buyers, including possible down-payment and closing-cost assistance. The article does not give prices, common charges or taxes.

What it means
Buyers and owners
No unit can legally be offered or sold until the Attorney General's Office accepts the offering plan for filing. Buyers should confirm that status and ask the sales team directly about price, common charges, taxes and whether they qualify for any down-payment or closing-cost help.
Landlords
This project shows that adding rooftop and rear-yard space to a building in a historic district went through Landmarks Preservation Commission review and was approved only with modifications. Owners in historic districts should expect that kind of review before similar work.
Tenants and voucher holders
These are condominiums for sale, not rental apartments. The material says nothing about rentals, affordable units or voucher use at this building.
The highlights
- LPC approved rear and rooftop additions with modifications in May 2023.
- The state AG has not yet accepted the offering plan, so units cannot be sold.
- The rowhouse at 427 E. 140th St. was built between 1897 and 1900.
Why it matters Landlords
Owners of historic-district buildings should expect LPC review, and possible modifications, before adding rear or rooftop space.
What to do: Check LPC requirements before planning additions to a historic-district building.

Background
In New York, a sponsor selling condominium units generally must submit an offering plan to the State Attorney General's Office, and the plan must be accepted for filing before units can be marketed or sold. Separately, exterior work, additions and similar changes to buildings in a city-designated historic district usually need approval from the Landmarks Preservation Commission, which can approve, deny or require changes to a proposal.
