The building was designed by Bart Prince, an American architect and leading proponent of organic architecture. The building had no traditional elements of Islamic architecture except for the qibla orientation and mihrab. The white building was shaped like a series of large steps, with rectangular towers with tall, narrow windows. Inside, the space was essentially one large hall, with a temporary partition dividing the men’s space from the women’s during prayer times. The ceiling stepped up in tiers, supported by thick wooden beams and rafters of bronze-coloured pipe.

Of his non-traditional design, Prince stated that arches and domes “were for their own time and place. It’s kind of silly to do that now.” The design was somewhat controversial among some members of the congregation, though ultimately it was the size of the mosque that led it to be replaced: this building could accommodate 250 people, and the new Centre would hold 600.
