Is it possible to make a glass which is transparent from one side but a white wall on the other side?

    No.  If the glass transmits light one way it also transmits it the other way.  All "one way" glass relies on having very little light on one side so that there is not much light coming from that side to compete with light on the other.  If the "outside" was in bright light it could APPEAR to be a white wall but there would remain small holes in it that could be detected with care.

    A one-way mirror, also called two-way mirror (or one-way glass, half-silvered mirror, and semi-transparent mirror), is a reciprocal mirror that appears reflective on one side and transparent at the other. The perception of one-way transmission is achieved when one side of the mirror is brightly lit and the other side is dark. This allows viewing from the darkened side but not vice versa.
