Is this from a Lego set?
It's most likely that this is not an official Lego set. There has been such a piece (the purple ones) but it never came in that color, therefore it must have been manufactured from a clone brand. There could be that 00.1% chance of it being a piece from an official Lego set, but based on the poor quality of the build in the image and the fact that Bricklink couldn't find it, I still think it's from a clone brand. Also, if any of the plates have only specific studs with holes in them that aren't in a reasonable pattern (such as outline of house walls), then there's a big chance that the plate came from Mega Blocks and not Lego™.
