In this paper we study the spectra of certain classes of Room frames. The three spectra which we study are incomplete Room squares, uniform Room frames and Room frames of type $2^ut^1$. These problems have been studied in numerous papers over the years; in this paper, we complete the three spectra. In addition we find a Howell cube of type $H_3(6,10)$. This corrects a previous claim of nonexistence of this design.doi:10.37236/346 fatcat:nkk33g2ayzgbzcexm7saakf5rq
