Date: March 2018-August 2018


Madrona and Willow Halls are two new student residences at the University of Washington. The landscaping for the residences was designed by OLIN, a firm based out of Philadelphia. The design includes a town square studded with granite boulders, which act as natural seats for students who want to study or relax.


370 Cubic Yards of Garden Mix Topsoil
250 Tons of Crushed Surfacing Base Course (CSBC)
140 Tons of WSDOT Class 2 Sand
70 Tons of Streambed Boulders
65 Tons of 4" Streambed Cobbles
15 Tons of Trail Mix


The oversized granite boulders are a prominent feature of the courtyard shared by the student residences. Each granite boulder weighs 8-10 tons and was handpicked at King Creek Pit by an architect from OLIN.

Our streambed cobbles form a beautiful drainage system around the edge of each residence and can also be seen in dry creek beds along the walking paths. Our Kapowsin Blue trail mix gravel lines the edges of the rock walls throughout the area.

The Seattle Times and Daily Journal of Commerce both published articles about the renovations.
