Bay Windows and Bow Windows: Which Fits Your Bethesda Home?

What Makes A Bay Window Different From A Bow Window?

What Each Style Does Well In A Bethesda Home

Bay windows usually create a more pronounced alcove, which can be a gift if you want a bench, plant shelf, or extra floor-to-ceiling visual interest.
