Located on a small 6,500 sf corner site with 25 ft of grade change, this project houses a local family foundation and investment company. Zoning regulations limited the building to two stories and required a significant number of on-site parking stalls, leading to an automated parking system.
Regionally produced cross laminated timber (CLT) was used as the primary floor and roof framing material and left exposed. CLT is supported by a refined steel frame, allowing the building to be erected in a short time, following the time-intensive concrete site work. All light fixtures, sprinkler heads, and penetrations were laid out and coordinated so the CLT panels could be pre-drilled at the factory, reducing issues in the field, simplifying the coordination of trades, expediting construction, and contributing to the refined aesthetic by eliminating the need for exposed conduit and sprinkler lines.
The project also benefited from collaborations between the project team of the architect, owner, contractor, and local craftspeople. The LEED Gold certified project strives to be timeless and convey permanence, while being environmentally responsible and forward-looking.
