The Trio Block is a modular set of seating forms designed to create flexible arrangements and informal gathering zones within plazas, courtyards, and interior common areas in commercial, hospitality, and public environments. Its combination of cylindrical and square geometries supports freestanding or anchored placement while enabling clustered, linear, or dispersed layouts. The solid, monolithic construction delivers long-term durability and a refined, minimal presence across exterior and covered landscape applications.
