Largo Lately

A Tale of Two Towers

Across California, residents are feeling the pinch of a limited supply of housing. Largo Concrete is answering call by building thousands of units each years across the state from high-end luxury condominiums to low-income, affordable apartments. Two of the most impressive developments are the New Century Plaza Residences in Century City and the Miro Towers in San Jose; this is their story.

Century Plaza

During the summer of 2018 Largo poured over 20,000CY of concrete foundations for the New Century Plaza Residences. The foundations will eventually support two 49 level condominium towers in the heart of Century City.

Working with the world renowned Pei Cobb Freed & Partners and Harley Ellis Devereaux architects, the decks are shaped like reuleaux triangles in an effort to pay homage to the iconic Century Plaza Office Towers on the north side of Avenue of the Stars.

In addition to the new towers Largo also performed the retrofit work on the adjacent historic Century Plaza Hotel.  Originally constructed in 1966, the renovation turned the building into a 400-key Fairmont Hotel with 63 condominium units on the upper floors.

Miro Towers

In the heart of silicon valley, across the street from San Jose City Hall, Largo is pouring the concrete on two of the city’s tallest buildings. The Miro Towers feature 630 new residential units and 633 stalls of parking spread across three levels below grade and 28 levels above.

Two mat foundations were installed over the course of two weekends in April 2019 totaling 13,100CY to begin the superstructure. Designed by Steinberg architects and DCI structural engineers, the development is scheduled to be open late 2020.

Silvery Towers

In January 2018 Largo topped out at the Silvery Towers also located in downtown San Jose. The east and west towers stand 22 and 20 stories respectively and sit atop of five parking levels, three of which are below grade. 

The buildings feature cast-in-place, post-tension decks with the east and west corner columns cast five degrees out of plumb. The “leaning” columns combine with meandering floor edges to lend a faceted appearance to the glass facade.
