Since the average residential addition project takes between 12-18 months to design and build, you should have started the process a few months ago. But indeed NOW is the 2nd best time.
You’ll need to clarify what you need to accomplish, how much money you have available, and a reasonable time frame before pulling the trigger. Bear in mind that average residential per square foot costs hover around $450 in lower Westchester County and interest rates have been lowered (writing in Oct 2025).
- In summary the project phases breakdown like this :
- 2-3 months to get your finances in order and assemble a design team
- 3 -4 months to design
- 3 months to approve
- 1-2 months to bid and write contracts
- 4-10 months to build
