Description
Just moments from iconic Christmas Tree Lane, beyond private automatic gates and a sweeping circular drive, this updated Mid-Century Ranch reveals itself as a rare Altadena compound: serene, refined, and thoughtfully reimagined for modern living.
Set on an expansive lot, this property offers two impeccably renovated residences that feel established yet sophisticated, completed with uncompromising attention to detail.
The main home features 3 bedrooms and 2 baths, centered around a beautiful open kitchen designed for both daily living and elegant entertaining. Light pours through the interiors, accentuating clean lines, curated materials, and a seamless indoor outdoor flow. Every upgrade has been executed with intention, delivering a level of polish rarely found in homes of this era.
A detached 2 bedroom, 2 bath ADU/guest house provides exceptional versatility, ideal for multi-generational living, extended stays, executive-level home office, or private retreat space. Between the two residences, a tranquil courtyard is anchored by a built-in bbq and intimate jetted pool creating a boutique resort ambiance perfect for quiet evenings or curated gatherings.
Centrally located in one of the community’s most cherished pockets, this estate feels remarkably secluded offering rare space and discretion in Southern California. In a neighborhood defined by resilience and renewal, this offering represents not only continuity, but the opportunity to step right into a home that has already been thoughtfully elevated.
A distinguished Altadena compound designed for those who value privacy, presence, and enduring quality.

5/10GreatSchools RatingParent Rating AverageWe have two children at Altadena Arts Magnet currently and both are doing well. We appreciate the sense of community and support felt by teachers, staff, and the families we have come to know. The arts curriculum is strong and our kids love their classes in music, theater, arts, and dance. We are also in the French Immersion program which has given our child the confidence and community with his cohort that has helped him thrive.Parent Review2mo ago - Eliot Arts Magnet

2/10GreatSchools RatingParent Rating AverageMy son just completed 6th grade and, as he is an artist, is learning so much from, not only his art and drama classes, but from the after school conservatory. He is taking two fine art/drawing classes, stop motion animation. As I have no artistic talent, he is getting much needed direction, support, and encouragement. In addition, he is getting strong core curriculum instruction. The conservatory, along with the Capturing Kids Heart program, have created a vibrant, kind, calm, and enriching environment for students to learn.A new principal was placed this year and has acclimated easily and taken the helm. I look forward to her increased attention on academics and insuring that students are being fully challenged academically as they are artistically.Parent Review2y ago - John Muir High School

4/10GreatSchools RatingParent Rating AverageOur family is proud to say that the third generation is now attending John Muir High School Early College Magnet in Pasadena, CA—and with good reason. This school has been a pillar of excellence, growth, and opportunity for our family and the entire community.John Muir High School Early College Magnet is truly a gem. Over the past several years, it has consistently delivered on its promise to provide both a strong high school education and the incredible opportunity for students to earn college credits—many even graduate with multiple Associate of Arts degrees by the time they finish high school. That’s right: students are leaving Muir not just with their high school diploma, but with college degrees in hand. This is a game-changer for families and students alike.The dedication of the teachers, staff, and administrators is second to none. They are passionate, supportive, and deeply invested in the success of every student. The programs here go beyond academics—they build character, confidence, and real-world skills.We are deeply grateful to have such an innovative and forward-thinking school in our community. John Muir High School Early College Magnet continues to be a source of pride and inspiration for our family, and we look forward to seeing future generations thrive here.Other Review1y ago
