When we originally planned out what we were going to do with our upstairs space, the first room off the stairway was designated as a sort of lounge or den. And sticking with our historically flavored tastes, the idea was that it'd be done up in midcentury/Space Age style. We got a bit of painting and decoration done, but it got caught up in the general warehouseification. But now it's in shape and functional again.
This view is from the window across the room. The orange chair is vintage midcentury, purchased by my Scandinavian-furniture-loving grandparents in the 50s or 60s. There's a shelf of science-themed barware, vintage periodicals, a screen showing a long playlist of midcentury educational, industrial, and promotional films (duck and cover!), and a small gaming table I upcycled from something the neighbors across the street threw out.
Looking a little right (towards the front of the house), there's shelves of games, books, and DVDs. Where the library has a lot of academic works, the emphasis in this room is on works for entertainment.
Facing across the room towards the window. We built shelves around the window for Stephanie's record albums. The shelf on the left mostly fiction (including a large collection of Trixie Beldens), with a Victrola on the right.
Looking left of there, it's a shelf full of mostly games (including Car Wars and an awful lot of 3rd edition GURPS books) and art books. The green chair and the lamp next to it are, again, vintage from my grandparents.
Farther left, the rainbow weaving is something my grandmother made, while the bongos used to belong to Stephanie's father.That shelf is, of course, a hidden door, sliding aside to provide access to the rest of the upstairs.
And this is the view from the hidden door. That's a vintage suitcase style sound system in front of the panel of pinups. It opens up into a record player and speakers.
It's not a big room (13' x 9' with a bit of a chunk bitten out of it), but it's cozy.
