RDG Planning & Design has acquired Walker | Coen | Lorentzen Architects, boosting its architecture staff by 30 percent and adding an Iowa City office. “We’re excited about this for a whole host of reasons,” RDG Principal Jack Patton said in a statement. “This is an opportunity that deepens our strengths in the corporate, restoration, government, and urban design markets – and adds new strength multi-family housing and urban redevelopment, not to mention adding Iowa City to our growing list of regional and national locations for RDG.” Matt Coen, principal at Walker | Coen | Lorentzen and now partner at RDG, said, “We’re going from being a great small firm to being a great, national firm – without losing any of our commitment to collaboration, to our local community, and to building strong relationships with our clients.” The acquisition adds 30 Iowa projects to RDG’s 600 projects in 33 states.
