Is now a good time for businesses to commit to long-term office space expansions?
Design firm Twelve has secured an additional 7,000 square feet at 45 Main Street in Dumbo, doubling its office space to 14,000 total square feet. The company is set to occupy the new sixth-floor area by early 2027.
Why it matters
This expansion signals steady demand for Dumbo commercial real estate, as firms that have been established in the neighborhood since at least 2015 commit to longer-term growth. The lease locking in $52 per square foot for seven years reflects the ongoing stability of this Brooklyn creative hub.
The seven-year lease expansion adds 7,000 square feet to the existing footprint, bringing the firm's total space at 45 Main Street to 14,000 square feet. Asking rent for the space is set at $52 per square foot, within a 476,000-square-foot building that recently saw a 50,000-square-foot renewal.

The details
The design firm secured the space on the sixth floor of the Brooklyn building without the use of a broker to manage the expansion. By extending its commitment for another seven years, the firm effectively doubles the office footprint it has occupied since its move to the site in 2015. The landlord, Two Trees, handled the transaction through its own in-house representation.
Timeline
2015: Twelve first moved into the office building at 45 Main Street.
Q1 2027: Twelve plans to move into the newly expanded sixth-floor office space.
The Home Front
This move highlights a broader trend among established Dumbo creative firms that are prioritizing long-term growth within their existing professional ecosystem. The consolidation of space by long-standing tenants reflects a move toward stability in the Brooklyn commercial office market.
Small business owners or renters should note that established firms in Dumbo are currently opting for long-term lease extensions in existing office buildings. If you are tracking local business trends, this move demonstrates a preference for staying put in established creative corridors.
The takeaway
The expansion shows that companies are increasingly doubling down on their current office locations for long-term stability. If you operate a small business, check your existing lease for options to expand into adjacent units before searching for new office space elsewhere.
What happens next
Twelve expects to finalize its move into the expanded sixth-floor office space during the first quarter of 2027.
