It can be less cost effective to finish a smaller space, and the total cost per square foot will vary based on the size of the space being finished.  Adding a staircase will cost more, too.

The expense of the project can increase if you need to add any kind of windows or skylights. If you don't plan ahead, you will need to remove siding and roofing, reframe the structure, add the window or skylight, and replace the siding and roofing. 

The cost of adding a bathroom will vary depending on the finishes desired as well as what stage of construction the home is in. If requested at planning stage, the plumber, framers, and electricians will be able to complete all work as they are finishing the rest of the home, resulting in some savings.

Are there other ways to increase the sq ft on a floor plan?

Adding a bonus room - whether on the second or third floor - is a great, cost-effective way to increase your square footage. Read more about adding a bonus room and expanding your house size (for the lowest cost) in these articles:

Can I add a third floor or attic later on?

A third floor can be a great space for a homeowner to finish themselves over time, with some significant labor savings, with some planning ahead before construction of the main home begins.  Check with your local jurisdiction to see what kinds of permits are required - you'll want to be able to count the area as finished square footage if you should ever want to sell your home.   

If you're thinking of ways to maximize your budget, make sure to get a full cost estimate from a custom home builder in the Raleigh/Triangle area before making any decisions.
