If the new total square footage of both houses is 16,000 sq. ft., how much is the smaller house being expanded by, in sq. ft.? Let's think step by step and output the final answer after "####".

Originally, the houses are 7300+5200=<<7300+5200=12500>>12500 sq. ft. in total.
The smaller house will be expanded by 16000-12500=<<16000-12500=3500>>3500 sq. ft.
#### 3500
