1788 Pepper Dr Designed in 1927 by renowned architect Wallace Neff, this distinguished Spanish Colonial residence presents a rare opportunity to steward an important piece of Southern California architectural history. Set on more than two-thirds of an acre, across two separate APN's, amid mature landscaping, the property captures the romance and craftsmanship that defined Neff's early work while offering the next owner the chance to thoughtfully restore and enhance a truly special estate. The main residence is comprised of four bedrooms and five bathrooms. Character-rich living and dining spaces open to a gracious patio, creating a seamless connection between indoor and outdoor living. Three spacious upstairs bedroom suites each feature private baths, while a fourth bedroom and bath on the main level offer flexibility for guests, a home office, or creative space. The expansive grounds unfold into a private retreat with established gardens, mature trees, and a swimming pool, providing an exceptional setting for entertaining or quiet enjoyment. Complementing the main residence is an award-winning 1959 mid-century modern guest house, a remarkable architectural counterpoint to the Spanish Colonial home. Complete with one bedroom, two bathrooms, a kitchen, a fireplace, and its own private yard, the guest house offers endless possibilities for extended stays, work-from-home use, or hosting family and friends. Adding to the property's rarity, the estate is situated on two separate parcels, creating unique flexibility and future potential. Rich with architectural significance and original character, this is a rare opportunity to reimagine and revitalize a legacy property in one of Altadena's most treasured settings.
