Welcome to 400 Baileys Run, a grand colonial home nestled at the end of a quiet cul-de-sac in desirable Springfield, Delaware County. Imagine the daily enjoyment of serene wooded views and calming sun-drenched spaces. As you enter the two-story foyer you will note every detail in this beloved home enjoyed by the original owners, and built by a family member. This main floor has everything! Impressive cathedral ceilings, a convenient office, a spacious formal living room, a gorgeous formal dining room, a sun room off of the kitchen with spectacular views of the back yard and Smedley Park, plus an exit to the large deck. At the center of the main floor is a beautifully equipped kitchen with a center island, breakfast bar and multiple ovens. The kitchen is the perfect compliment to all of the entertainment possibilities this main floor offers. As you retreat to the upper level of this home, you will appreciate the builder's attention to detail. The stunning front and back staircase has intricate wrought iron and gleaming wood. The bright, open hallway gives access to four large bedrooms including the impressive owner's suite. This space is exactly what is needed after a busy day. Have your morning coffee in the sitting area, another sun-drenched space with incredible views from floor to ceiling windows. And when summer becomes winter, turn on the fireplace and continue to relax here before enjoying your jetted tub in the en suite bath. Each of the other bedrooms are spacious and have great closet space plus hardwood floors and crown molding.
