We design for equitable use. Our goal is to create spaces that do not disadvantage or stigmatize any group of users.

Our designs focus on flexibility, so that the lighting supports use by those with varied preferences and abilities.

We value the voices of those who are directly impacted by the application of our design process.

We understand our role as designer to be a facilitator instead of an expert.

We aim for sustainable design
