NW23 & NWGS Mixed-Use Buildings
PORTLAND, OREGON
After a natural gas explosion damaged two buildings on NW 23rd Avenue, R&H was hired to restore and rebuild. The first building, an award-winning development called NWGS, was stripped down to its structural core and seismically upgrade before reconstruction. The finished building features retail space, office space and penthouse level private residence. The residence includes high-end imported finishes such as Italian floor tiles, Japanese restroom tiles, French countertops and Brazilian exterior tile requiring extra attention to detail.
The second building was damaged beyond repair and a new four-story mixed-use building, called NW23, was constructed in it’s place on this tight, urban site. The ground floor retail space is currently leased by Steven Smith Teamaker, which was also built out by R&H.

Progress
NW Glisan Street was originally completed in 2000, therefore the building was not designed to current seismic code. To bring the building up to current code, R&H teams used silicone sheets during the building’s reconstruction. These sheets not only permit flexibility of the design to the building’s structure, they also act as a weather barrier. The sheets, thin flexible membranes, sit against the side of the structure and allow the building to drift up to 2.5” in the event of an earthquake without compromising the weather barrier. This 2.5” of drift is equal to an additional 200% of elongation movement and 75% compression movement, giving the building’s envelope the movement needed to better withstand an earthquake.
