About this House

What's unique:Front porchAlfresco diningVersatile stone patioFully fenced yardAttached shed spaceRadiant heated floor
Welcome to 21 Calam Avenue! Picture yourself unwinding on your front porch with your morning coffee. This charming Bungalow, a true example of 1920s craftsmanship, is a treasured piece of Ossining's architectural history. This is A Sears, Roebuck and Co. home and is one of 102 homes originally built in Ossining between 1908 and 1939. This home truly has it all, featuring a convenient main floor bedroom and full bath with radiant heated floor—so practical! You'll love the updated eat-in kitchen and formal dining room, perfect for hosting Thanksgiving this year. The spacious living room invites you to binge-watch your favorite shows and create lasting memories with friends and family.

Head upstairs to find two generous bedrooms and another full bath. And here's the best part: you can beat the heat with 2-zone ductless air-conditioning that’s both quiet and efficient.

The basement offers endless possibilities. Whether you need storage, a laundry area, or a great finished space currently set up as an office (153 SF), it’s all there without affecting your living space.

Now, let’s discuss the great outdoors: a fully fenced yard and a 1-car garage provide ample space for your vehicles with an attached shed space for storage. The lot, sized at .16 acres, has plenty of room for a fun game of frisbee, a picnic, swings—the options are limitless. Imagine setting up a fire pit to roast marshmallows, watch fireflies, or just gaze up at the stars.

The versatile stone patio with retaining wall create an inviting space for alfresco dining, just steps away from the kitchen.
