Office space in Flatiron
Prewar lofts on Unicorn Lane, the heart of New York’s growth-stage tech.
Flatiron is the center of gravity for New York’s growth-stage tech. The district runs roughly from 14th to 23rd Street around Fifth Avenue and Broadway, and its prewar loft buildings, with big windows, high ceilings and open floors, are why companies keep landing here.
It sits on Unicorn Lane, the Broadway corridor where most of Manhattan’s AI and venture-backed leasing has concentrated this year. Well-built floors don’t sit long, so it pays to know which buildings fit before you tour.

From the broker
What we’re seeing in Flatiron
Flatiron still works best for growing tech and consumer teams because within a few blocks you can find everything from a furnished sublease for a small team to a full-floor headquarters. The biggest difference between two similar floors usually isn’t the asking rent; it’s how much work the landlord will do and how quickly the space can actually be delivered.

Questions
Office space in this neighborhood: common questions
How much does office space cost in Flatiron?
Asking rents for the spaces Nomad is showing in Flatiron currently run $56–$130 per square foot per year, with a typical asking rent of about $90. For a full space that’s roughly $24K–$246K a month in base rent, before escalations, taxes and operating expenses. Final terms depend on the building, the condition of the space and the lease length.
What size offices are available in Flatiron?
Listings Nomad is showing in Flatiron range from about 4,000 to 26,600 rentable square feet, mostly direct leases, with some subleases. Most of what fits a growing team never reaches a listing site, so a Nomad Space Book also covers off-market options.
Is Flatiron more expensive than NoMad?
Right now, typical asking rents in Flatiron (about $90/SF) are slightly higher than NoMad (about $84/SF), based on Nomad’s live inventory in both. The gap depends on building class and condition, so comparing specific floors matters more than neighborhood averages.
Can you find furnished or sublease space in Flatiron?
Yes. Nomad’s current listings include furnished options and subleases. A furnished sublease can get a team in quickly, usually for the rest of the existing tenant’s term.
How far is Flatiron from Penn Station?
About a mile. The R and W run from 23rd Street to 34th Street–Herald Square in two stops, a short walk from Penn Station. The F and M from 23rd Street and Sixth Avenue go there too, and PATH runs along Sixth Avenue.
What kinds of companies lease offices in Flatiron?
Growth-stage tech and consumer companies, especially in AI, fintech and health. Adyen leased 90,000 SF at 111 and 115 Fifth Avenue this year and Synthesia took 50,000 SF. Nomad has moved companies including Instant, Authentic and Redesign Health here.
