Timeless Cape Cod in Colonial Village with a major added bonus. Prepare to be charmed and impressed. This delightful Cape is attractive and highly practical and comes with an additional two story building with many options. The neat 3 bedroom home features a first floor primary bedroom suite with a full bath, living room with fireplace, dining adjacent to the country kitchen, and two bedrooms and full bath on the second floor. The separate two-story building offers a range of options to the new owners. On the first floor there are possibilities including as a two-car garage, or for studio space, indoor play space, or home office. There is a spacious bedroom and full bath on the second floor. Taking the options further, this building would be ideally suited as an ADU by converting .... by converting the first floor into a full kitchen with adjacent living and dining space. This "bonus" building can be an apartment, ADU, and even potentially sold separately from the main house on its own subdivided parcel. The almost half acre property includes a remarkably private landscaped yard and ''architect designed'' tree house.
