Porosity is about designing voids as vividly as solids – creating architecture that breathes with openness, connection, and light. Rather than monolithic masses, Steven Holl Architect's projects are often sliced or permeated to invite engagement. SHA’s methodology of porosity dissolves barriers between inside and outside, private and public. It yields architecture that, like a sponge, absorbs and channels the life around it – light, air, people – to create vibrant, integrated spatial experiences.
