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.
