meet the studio 

At UDA, we’re one team with a collective passion for revitalizing cities. We’re all about creating vibrant public spaces and exceptional places for people of all walks of life to live, work and play. Not only is our craft rooted in the traditions of hand-drawing and illustration – we have yet to discover a more powerful way to begin bringing visions to life – but we’re also committed to allowing local traditions to guide the design and development of reimagined communities. We believe deeply in the interaction and connection of architecture to the creation of public space, and you’ll often find us shaping policy to further improve the urban condition for everyone.
