If you're unfortunate enough to live in a region cursed with bitter winters (I know I am!), you know the pain of keeping your pad heated. One solution? Build an insulated room within a room to stay focused and toasty.
German architectural firm Davidson Rafailidis created this prototype, constructed out of plastic and wood, that hooks up directly to a window for both light and warmth.

Y'know, whatever's your thing. [Core77]
