SAMPLE ARCHITECTURAL PORTFOLIO All projects here were designed and all drawings were completed solely by Benji Amsden, Jr. from conception to completion of construction, with the exception of the Univ. of Colo. Bio-chem Bldg. which Mr Amsden was on the design team and was instrumental in designing the Tower and the Professor’s offices. He also built the scale model for Campus approval.
