House 77 by dIONISO LAB in Póvoa de Varzim, Portugal, doesn't belong to a symbologists though you can be forgiven for making that mistake. The first thing that strikes you about this uniquely styled home is the outer façade which features aluminum shutters perforated with symbols.
The symbols don't belong to a secret society (though that would have been fun) and in fact is a homage to the fishing town it is located in. The concertinaed metal shutters also provide privacy and lend an intriguing stimulus to the house.
