Is 5,000 sq ft a normal size for Connecticut?

U.S. median

11% of new homes completed in the Northeast fall in the 4,000 sq ft or more range that a 5,000 sq ft build sits in, against 23% for the most common bracket (2,400–2,999 sq ft).

The Census Bureau measures every new single-family home completed in the country. In the Northeast — the region Connecticut sits in — the median came in at 2,459 sq ft and the average at 2,644 sq ft. A 5,000 sq ft build is therefore 103% larger than the regional median. Homes this far above the median are a small share of what actually gets built, and cost per square foot tends to climb rather than fall at this scale because the extra area is usually specified to a higher standard.
