Look for a partner whose experience matches your project type and who can clearly explain design, permitting, contractor coordination, construction oversight, communication, and completion. Review relevant residential work and ask how architectural, interior, sustainability, and technical decisions will be coordinated. A design-led practice may be especially useful when the project involves additions, historic preservation, or a whole-home renovation.
