This extensively expanded residence offers a rare opportunity to own a truly unique property in the Rowland Heights area. Originally built as a 3-bedroom, 2.5-bath home with 1,953 sq ft of living space, the property was substantially expanded with permits, with construction completed in late 2017 and 2018. The home now features a total of 9 bedrooms and 8.5 bathrooms, including 6 suites, providing exceptional flexibility for large or multi-generational households, extended family living, or other specialized residential needs. A significant portion of the households nearly 80% of the house was newly constructed during the expansion, offering a more modern layout and systems compared to the original structure. The property stands out for its generous overall size, which is uncommon in the surrounding neighborhood, and benefits from enhanced privacy with no neighboring home on one side. The front yard has been thoughtfully improved to accommodate ample parking, addressing a common concern for larger households while maintaining privacy. Additional features include a 3-car garage and four separate air conditioning units, allowing for efficient climate control throughout the home. At the current offering price, the property presents a compelling value on a price-per-square-foot basis
