Located in a sought-after Diamond Bar neighborhood, this modern residence offers a unique and highly functional floor plan. The open-concept great room is filled with natural light and connects seamlessly to the kitchen, creating an inviting space for daily life. The well-appointed kitchen features abundant countertop space and stainless steel appliances, providing a practical and spacious area for cooking and gathering.
This home offers exceptional versatility with bedrooms located on both levels. The main floor features a desirable primary suite, a private retreat with an en-suite bathroom, a large, glass-enclosed shower, and direct sliding-door access to the backyard. Two additional bedrooms and a second full bathroom are also conveniently located on the main level, ideal for family, guests, or a home office.
The second level is dedicated to an expansive, loft-style bedroom. This private and oversized room offers a unique retreat and is highly adaptable, whether used as a junior suite, a combination media room and guest quarters, or a quiet study, providing valuable separation from the downstairs rooms.
Some upgrades include a new tile roof (2017), fresh paint outside (2018), a new condenser (2020), a whole-house repipe and retaining wall (2021), and a new water heater (2022). The property also includes a low-maintenance backyard, made easily accessible from the primary bedroom. Its location is exceptional, situated within the acclaimed Walnut Valley Unified School District and zoned for South Pointe Middle School and Diamond Bar High School. Residents are just a short distance from local shopping and dining, with convenient access to the 57 freeway for regional commuting.
