SONO 50:
Where Chic
Meets High-Rise
Office Lofts

The newly-renovated and transformed SONO 50 now represents a first-of-its-kind office space designed to meet 21st century needs at every turn. Constructed in 1970, SONO 50 is now where chic meets high-rise lofts – 200,000 square feet that towers 14 stories and offers panoramic views of historic South Norwalk, Norwalk Harbor and beyond to Long Island.

The First Impression: Industrial style blends with organic sophistication.

The building’s first-floor entry was designed to complement historic SoNo with new architectural steel canopies, brick, designer lighting and reimagined storefronts. The inviting park plaza and landscaping provide a natural environment and contrast to the new 23-foot glass towers at both the North and South entries of the building.

And the lobby: 5,000 brand new square feet constructed to perfectly accommodate the impressive entry with a comfortable co-working area, cafeteria, and convenient bank access.

SONO 50’s lobby, one of the most unique in Fairfield County, is designed with 100% custom-made organic materials for a loft industrial look on one hand, yet chic and artistic on the other.

Not just best-in-class.
Just plain best.

SONO 50 provides the largest, and highest quality, amenity package available in the local market with ample on-site parking, 100% generator back up providing continual power to the entire building, adjacent to a large city-owned park and plaza, modern conference rooms, video conferencing, WiFi, lounge and gaming areas, a state-of-the art gym with spa-like locker room and a convenient bike rack at the lobby level. Once you step into SONO 50 you experience the full benefits of first class amenities befitting a Class A office building.
