August 20, 2026

We've Reached the Top!

40 Main Street under construction in August 2026

There is a profound moment in the life of a new architectural landmark when abstract lines on a blueprint permanently transform into physical reality. Today, we are thrilled to announce that 40 Main Street has reached that exact milestone: Our structural framing is officially complete, and the building has topped off.

Standing at its full five-story height at the iconic corner of Main and Edith, the building’s striking silhouette is now fully realized. Brought to life through the expert construction management of Base Builders, this achievement marks our most significant construction milestone to date—permanently shaping a sophisticated new chapter for the Los Altos skyline.

A Rare Perspective Realized

While reaching the roofline is a triumph of engineering and technical precision, the true reward is the breathtaking vantage point it reveals. To celebrate the completion of the framing, our team recently stepped out onto the upper levels to experience the views firsthand.

The results are extraordinary.

From the expansive window openings of the upper residential levels, the view opens up into a sweeping, uninterrupted panoramic vista of the valley and the Santa Cruz Mountains. In a town that deeply values its intimate, pedestrian-friendly scale and historic charm, a protected perspective of this caliber is completely without rival in the downtown corridor. It is an architectural privilege that simply cannot be replicated.

Crafted for Every Lifestyle

As the building stands tall, the layout masterfully demonstrates the "Contextual Modernism" envisioned by William Maston and expertly engineered by SDG Architects. Standing inside the completed frames, you can clearly feel how the building caters to two distinct, luxury lifestyles:

  • The Upper Levels (The Mountain Vista): Designed for those seeking an elevated, panoramic sanctuary. These homes feel entirely private, floating above the peninsula with the horizon framed like a living work of art.
  • The Lower Levels (The Village Pulse): Created for those who love the immediate energy of the neighborhood. These residences sit at the perfect height to capture the tree-lined charm and walkable pulse of Main Street’s world-class dining and boutique retail, all while holding a captivating mountain view.

Moving Into the Next Phase

With the structural skeleton now complete, 40 Main Street is preparing for its next major evolution. In the coming weeks, our teams will begin the meticulous installation of the building’s exterior enclosure—including high-performance, European-crafted windows and doors from Eco Windows and a premium mix of facade materials designed to harmonize beautifully with the surrounding landscape.

The vision is no longer a plan for the future—it is a five-story reality in the heart of the village.
