After years of negotiations and waiting for financing, The Dermot Co. and the Poulakakos family have finally closed on their 99-year lease of the Battery Maritime Building with the city.

The lease, according to public documents, also has five, 10-year options to renew. Dermot principals were traveling and unavailable to comment, said a spokeswoman. The city’s Economic Development Corp. declined comment.

Architect Ishmael Leyva and interior specialists I©RAVE can now work their magic on the space to create restaurants, a live performance space, catering and a rooftop restaurant and bar.

Previous announcements said a new building will rise next door to accommodate a boutique hotel, now planned for just under 70 keys.

The Poulakakos family owns several food concepts including Harry’s Italian, Ulysses and Financier Patisserie.

Completed in 1909, the dramatic multi-story cast iron and copper BMB is now used for boarding the free Friday, weekend and holiday Monday ferries to Governors Island.
