Look for an architect whose portfolio reflects your project type, design goals, and desired level of involvement. Review experience with remodels, additions, permitting, interiors, and construction coordination. Ask how the architect communicates with consultants and contractors, what services are included, and how fees relate to the project scope. A collaborative consultation can help determine whether the studio is a strong fit.
Talk with the studio about your remodel goals, scope, and design needs.
