Architectural Lighting Design is how you take a project to an altogether another level. Like the fourth dimension. You want your project to be unique, to have that particular quality, feeling, ambiance, etc. If so much thought goes into the design of a project, why not take it through dusk into evening and night time.
From party or intimate to clean up? Poor lighting design can severely ruin a good project. Excellent lighting design enhances the architectural experience and creates interest, spatial ambiance, mood, etc.
