The sentence is
The project would construct a 2000 square (foot/feet) kitchen.'
I put 'The project would construct a 2000 square feet kitchen.'
My senior reviewer changed feet to foot. Why?
If I switch up the order, feet definitely sounds better:
The project would construct a kitchen with a floor area of 2000 square feet.
Online searches say that foot is used to refer to a singular unit of measurement (e.g. the area is one square foot). They also say that people generally use 'square foot' to describe the size of a room or space.
If I were to say it out loud, I would be inclined to say 'the apartment has a 2000 square foot kitchen, and the living room is 2000 square feet.'
