Back on the market. Developers and contractors — an incredible development opportunity on one of the last remaining 2.6+ acre gated estates in Chatsworth. Full architectural plans and drawings are available to convert the existing “Carriage House” into a 2-bed, 2-bath, approx. 1,200 sq ft ADU and add over 300 sq ft to the main home (permits from 2019 have expired). Whether you're looking to renovate, expand, or explore lot-split potential (buyer to verify), this property offers unmatched flexibility. The main residence is ready for cosmetic updates, while the second structure — with its own address — presents an ideal rebuild opportunity. Designed by renowned architect Robert Byrd, the original home retains signature character and charm. Existing amenities include a lighted tennis/pickle
