The N2 Innovation District is now home to one of greater Boston’s cultural gems: the Boston Ballet School.

The school’s September opening was the latest addition to Crosspoint Associates’ transformation of the former Newton Technology Park to a mixed-use destination on Needham Street called Newton Nexus.

When complete, Newton Nexus will be also home to a boutique grocery (bfresh), retailer TJX Companies with two of their brands (TJ Maxx and Sierra Trading Post), restaurants (Qdoba and two others to be filled), a bank and AAA. Anchoring the northern boundary of the N2 Innovation District, Newton Nexus also offers 10,000 square-feet of second floor office space adjacent to the Upper Falls Greenway.

“Cultural intuitions and non-profits are critical to innovation and every bit as important to our vision for the N2 District as the technology and life sciences companies that are also moving here,” said Chamber President Greg Reibman.

“We’re fortunate that Boston Ballet chose Newton and we applaud Crosspoint for recognizing the cultural and economic benefits bringing the Ballet School here.”

With a ribbon cutting in early September, Boston Ballet inaugurated the school’s new state-of-the-art training facility. The site offers seven rehearsal studios, and training space, and creates meeting points for students and parents to interact, helping foster a true dance community.

More than 20 percent of Boston Ballet’s professional dancers are trained in the Boston Ballet Schools, making this facility an important part of the long-term growth and sustainability of the overall program.

“I am proud that our new studio is a vibrant learning space for the surrounding communities and reflects the exceptional dance education we provide,” said Artistic Director Mikko Nissinen.

The 26,550-square-foot dance school, designed by global architecture firm Gensler, also features increased locker room space for students, a physical therapy room, family restrooms and dedicated areas for studying and stretching. The design is the result of input from more than 400 members of the Boston Ballet community.

“The design team expertly addressed the growing needs of the community served by the studio while reflecting the high-quality dance education offered by Boston Ballet School,” said Jeanne M. Nutt, managing director and principal of Gensler and member of Boston Ballet’s Board of Overseers.

“Students of all ages, faculty, and families alike will enjoy the warm design of the new Newton Studio for years to come.”

The new studio implements universal design principles — a philosophy that promotes accessibility and goes beyond ADA compliance. The School serves a diverse population of students ages 2 to adult with a variety of programming.

Boston Ballet School relocated from 863 Washington St. in Newtonville. Boston Ski + Tennis, which relocated from 170 Needham St., opened at Newton Nexus just over one year ago. TJ Maxx and Sierra Trading Post are next to open at Newton Nexus in mid-October, followed by Qdoba shortly after.
