Enormous plant (Higham Hill E17)

I have been looking after this plant for a friend, who now has no space for it at home. It really needs a greenhouse, The pot it is in has a diameter of 50cm. From one edge of the pot to the furthest leaf (with it's long stem supported on the table) it is about 1.5m. It urgently needs repotting as it puts out roots trying to find better soil. If no-one wants it I will chop it up for my compost heap.
