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

Dwaal offers architectural lighting design at a high level of creative design, research and development, and technical proficiency. Dwaal has a reputation for advocating for the end-user while considering the broader goals of the project. Our goal is to design lighting that will make a positive difference.
