1510年韦伯斯特
16 stories of mass timber change the game for affordable housing
Located in the heart of downtown Oakland, 1510年韦伯斯特 is 19 stories, 16 of which are mass timber. Designed using the tall wood code provisions in the 2021 IBC, the 187-foot-tall project includes 179,020-sf of combined housing, 办公室, ground-level retail/commercial space, 和设施.
Project developer oWOW’s goal was to provide affordable housing for “the missing middle,” or households earning between 80 and 120 percent of the area’s median income (AMI). They achieved this with mass timber, and more than 15% of the 222 residential rental units are designated as affordable for households earning 80% of the AMI.
Saving Money, Saving Time
The team also challenged the norm that mass timber is best suited for projects where the wood can be left exposed.
oWOW designed 1510年韦伯斯特 using veneer-based mass timber products, including mass ply panels (MPP) and mass ply laminate (MPL) columns, in an innovative point-supported beam configuration. It is the first prescriptive Type IV-A building in the U.S., and the requirements for this construction type meant they had to cover all the wood with three layers of gypsum wallboard. 然而, the choice to use mass timber still allowed oWOW to realize a $30 million savings in net project cost over that of a traditional concrete project of this scale.
“Wood is certainly a beautiful, 可持续材料, which is important to us,” says oWOW President Andy Ball. “But our real target was speed of construction and cost, and that’s why we used mass timber for 1510年韦伯斯特. And that’s why we were also okay with covering it all up. I think people need to think beyond the beauty of wood and accept the fact that mass timber is just a great building material.”
