Picture a gentle hillside crowned with the spreading limbs of an ancient tree... add generous one-acre homesites and a portfolio of upscale, appealing designs. That's the formula for Century Oak, Rouse/Chamberlin's newest community in Oxford in Chester County. The location, near the heart of the Brandywine Valley, is convenient to corporate centers in Philadelphia, West Chester, and Wilmington and Newark in Delaware. The recreational attractions of the Chesapeake Bay are less than an hour away. Military and civilian personnel and their families will appreciate Century Oak's close proximity to the Aberdeen Proving Ground in Aberdeen, Maryland and the base realignment (BRAC).
