Unknown indoor plant

Observation - Unknown indoor plant - UK and Ireland. Description: Hi, we used to have a very unusual indoor plant in our office area. Unfortunately it varnished but I'd love to know what it was. Pictures show it in bud (pink) and then in flower (white). Hopefully someone will be able to identify it?
