Architecture Research Office Collection

Growing out of our material explorations for Knoll New York, we developed a line of acoustic, architectural felt finishes with Spinneybeck | FilzFelt. These absorptive panels, screens, and baffles continue our prior design explorations that transform the qualities of humble materials while addressing an increasing market need for innovative acoustic products.

The Architecture Research Office Collection combines the natural beauty of wool felt with pattern and texture to create architectural finishes that are elegant, acoustic, and easy to install. These felt finishes add visual interest and improve environmental comfort. As part of our ongoing collaboration, we incorporate these products in several Knoll locations across the country, including Los Angeles, Philadelphia, San Francisco, Houston, Washington, D.C., and the New York Refresh.

ARO Block

ARO Block is a series of modular acoustic tiles inspired by architectural cladding. The product arose out of a need to reuse post-industrial remnant material at FilzFelt’s manufacturing facility.
