How much does 54 West 21st Street [Partial 4th Floor] cost per month?

Asking rent is $72 per square foot per year. At 3,960 sq ft that is $285,120 annually, roughly $23,760 per month before electricity, which typically adds $2–4 per square foot per year. Rent is a starting point; free rent, improvement allowance and escalation caps are all negotiable.

How many people fit in 54 West 21st Street [Partial 4th Floor]?

About 23 people at 175 sq ft each, which allows for meeting rooms, phone booths, a pantry and circulation. A denser open-plan layout could take 28; a layout with private offices would suit closer to 18.

Where exactly is it?

54 West 21st Street sits in Flatiron, Manhattan. Transit: N/Q/R/W, 4/5/6, F/M, L at 14th and 23rd. Neighboring submarkets: NoMad, Union Square, Chelsea. The heart of Midtown South and the centre of NYC’s venture-backed tech cluster.

How does the rent compare to the rest of the market?

The median across Nomad's current New York availability is $75 per square foot per year, so this space sits about 4% below the median.

How quickly could a team move in?

A furnished or pre-built floor can be occupied two to four weeks after signing. If the space needs a custom fit-out, expect 10–16 weeks: two to three weeks design, three to four for permits and long-lead items, six to nine construction. Nomad runs both the lease and the buildout, so those phases can overlap.

Beyond rent, what is negotiable on a space like this?

Free-rent months, tenant-improvement allowance, escalation caps, security amount and form, expansion or renewal options, and the restoration clause. On a tenant-only mandate, all of them are argued for you.

What happens between an offer and keys?

Letter of intent, lease negotiation, then buildout or move-in. Furnished floors run two to four weeks after signing; custom fit-outs typically ten to sixteen. Starting design during lease negotiation compresses the calendar.
