Each of the four San Gabriel projects, designed by Kengo, are within half a mile to the heart of San Gabriel City. San Gabriel Valley is in Southern California and is known for its proliferating business, picturesque terrain and environment, and its location between major interstates in the Los Angeles County. Accessible to the entire SoCal region, it is approximately 10 miles from Los Angeles, acting as a crossroads to the many freeways, such as Interstates 5 and 710, making the city a perfect location to visit.
