Maybe the space wasn't laid out well. I would imagine, with only 700 sq ft per floor, a good portion of that is taken up by the stairs. My condo is a flat in a 100-year-old building, built before the "open concept" plans came into vogue. It means out rooms are separated and lets my wife and I do different things in different parts of the house.
People used to raise families in these old buildings with 1000 square feet. Their third-spaces weren't taken over by profit-seeking companies and their interests took them outside the home. 2000 square feet for 2 people seems utterly ridiculous!
What are you guys even doing? Or maybe the 1400sqft included the garage?
If they hadn't done the math I'd have suspected a typo.
I'm in a place not all that much larger (1800 sqft) and it feels pretty luxuriously large for just me and my partner. Big open kitchen, two living rooms, 2.5 bathrooms, three bedrooms (one used as an office for myself) and a dedicated office for my wife.
We had to sleep on different floors. Master bedroom was barely larger than the queen bed, and no way 2 people could sleep in there because it would get blazing hot in minutes.
Garage was similarly minuscule. GF had a tiny suv and still couldn't open both doors.
I figure 1000 square feet per adult is just about right.
