Unit Mix & Floor PlansThe building's recurring floor plans, found by grouping units with identical beds, baths and square footage in county records. Larger groups are the building's standard layouts; leftover units have one-off sizes.

Every unit: size vs estimated valueEvery unit in the building as one dot: across is its size, up is our current value estimate, and color is its bedroom count. Vertical columns of dots are recurring floor plans; the height spread within a column shows how much floor, view and condition move prices for the same layout.

Value by Floor & LineAverage estimated price per square foot by floor range, using unit numbers to infer floors. Higher floors usually price higher — the gap shows how much the view is worth here.

Unit lines by $/ft²Condo units stacked vertically share a unit line — the last digits of the unit number (like 05 in 1205, 1305, 1405). Lines share a layout and exposure, so comparing estimated $/ft² by line shows which position in the building commands a premium.
