Mount Helix – Historic Mid Century Modern

Nestled in a peaceful enclave on a private road, the historically designated Casady home stands as a quintessential example of Southern California Mid Century Modern architecture and benefits from Mills Act tax savings. Originally commissioned by Si Casady and brought to life by the esteemed architect Art Decker in 1961, this residence was later acquired and lovingly preserved by Decker himself for over fifty years. Built by the distinguished midcentury builder John Mortenson, the home features exceptional custom craftsmanship, ample storage, and well-maintained details. It has been tastefully updated with bespoke modern cabinetry, high-end appliances, and luxurious fixtures.

Positioned on a gentle hillside, the property is surrounded by a mature olive grove, coastal oaks, and eucalyptus trees, offering a sense of serene seclusion. Each room is designed to capture stunning views of city lights and mountain sunsets, ensuring an optimal flow for daily living and a clear separation between public and private spaces. The floor plan is thoughtfully designed to provide natural vistas from every room.

The main home includes three bedrooms, each with its own bathroom, plus a versatile flex space. The largest bedroom, measuring 23′ by 13′, adds significant flexibility to the layout. There is also a well-equipped laundry room with built-ins and a sink. The kitchen boasts an open layout, JennAir appliances, and a beautiful skylight, creating a bright and welcoming space. The living area features high ceilings with exposed beams and expansive picture windows that allow natural light to flood the space.

The home includes 22 owned solar panels (NEM 2.0) and additional panels on a power purchase agreement, enhancing energy efficiency. A recently added, permitted office/flex space seamlessly integrates into the landscape, maintaining the home’s architectural lines without presenting a false sense of history.

Despite its tranquil setting, the property offers convenient access to major freeways, the dining and shopping options of La Mesa Village, and everyday essentials. This remarkable home combines the tranquility of private living with the convenience of urban amenities, making it a true gem in Southern California.
