18 Green St, Castine, ME 04421
About this home
This very special bungalow on a double in-town lot will steal your heart! Bright, sunny main floor with fireplace, open living and dining spaces, spacious floor plan including first floor bedroom and bath and wonderful sun room. Upstairs there are two more bedrooms with two more full baths. Extra space off stair hall allows for a media room and another sleeping alcove or office nook. Hardwood floors throughout. There's tons of storage with a laundry room as well as a pantry area on the first floor behind the kitchen, where it connects to the two car attached garage. A gracious wraparound porch with a section set up for a screened porch gaze over a lush, gently terraced lawn (actually a separate lot!) with peeks at the harbor below. There is so much more to this home than meets the eye, it must be seen to be fully appreciated. The location cannot be better, within close reach to the charming Witherle Memorial Library on Castine's lovely, historic town common, and just steps down the hill to Castine's vibrant harbor front, boat moorings, and center of the village. If you are looking for a home with built-in extra value in its potential to have a legal, secondary dwelling/studio/guest cottage (subject to successful permitting), all on town water and town sewer. .. don't wait, this one will go fast!
