While the Ace Hotel is often credited with kicking the neighborhood transformation into high gear, the trendy NoMad Hotel, developed by the same people, can be credited with getting the NoMad moniker to stick. Plans for the renovation of the 1903 Broadway building were unveiled in 2008, and the NoMad welcomed its first guests last year.

The Real Deal reported today that the NoMad owners bought the neighboring building for $6 million with plans to expand the boutique hotel.

The Whitman, a condo conversion of the old Plumbers Local 1 building, introduced itself to the neighborhood in February, dropping its three full-floor residences on the market. One has allegedly been claimed by former first daughter Chelsea Clinton and her husband.

The plans for this condo conversion were revealed back in 2011, and sales started earlier this year. Dutch designer Piet Boon is the creative mind behind this development, named Huys, and it's seen strong interest from buyers—StreetEasy shows 36 of the 58 units are already in contract.

The former International Toy Center is one of the more recent condo conversions in the neighborhood. The Witkoff Group is behind the under-construction project, which will have 125 homes. Sales have yet to begin, but a few pricing details were released: 1BRs will start around $1 million and 5BR penthouses will ask $25 million and up.

One of the few new constructions in the neighborhood, 241 Fifth began sales earlier this month. Developed by Victor Homes and designed by ODA Architecture, the condos have been well-received; 30 of the 46 units have entered contract.

Despite opposition from local community members, the community board approved plans for a 23-story hotel at 250 Fifth Avenue last October. However, it doesn't seem like construction has started yet, as permits with the DOB are still pending.

After a few years of starts and stops, Christian de Portzamparc's crystalline 400 Park Avenue South (aka the Fortress of Glassitude) finally got headed in the right direction—skyward—earlier this year. The building's shard-like look will add some serious pizazz to the neighborhood, and it have 22 rentals on the lower floors and 99 condos on the upper levels.

Last summer, we learned that L.A. hotelier Sam Nazarian and Moin Development Corp. picked up 444 Park Avenue South with plans to convert the building into a hotel with three bars and restaurants. Since then, we haven't heard anything. If you have intel, please do hit up the tipline.
