The line premium — where you sit sets the price
Same-3BR prices, time-controlled to today’s dollars, split by line — exposure, light, and layout vary stack to stack within a building.
Bar = today’s 3BR price for that line; right column = premium vs. an average 3BR.
And by floor
Same 3BR, time-controlled to today — higher floors, higher clears.
The 3BR trajectory
Every recorded 3BR. The building trades thinly year to year, so the story is the long arc, not any single year: 3BRs have moved from roughly $4.25M in the mid-2000s to about $3.93M today.
Each dot is one recorded sale, by close date and price; the line is the median for each year.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01391-0034) and verified listing data. Co-op apartments are priced by unit type (bedroom count) rather than per square foot — square footage isn’t officially recorded for co-ops, and room counts carry some agent-entry inconsistency, so bedroom type is the reliable spine. Non-arms-length transfers and storage/parking are excluded; line and floor premiums are time-controlled to today’s pricing. Where transaction volume is too thin to support a figure, none is shown.
