All the teachers at hogwarts have a bedroom so i have been wondering how would look the bedroom of Severus at hogwarts?

I always thought his bed chambers would be pretty large- very dark, not much light in it at all... A fireplace... and a small desk for reading and writing. His bed would be very large... I imagine green velvet curtains surrounding it; large royal-ish sheets covering it- that're of course, green. xD oh, and plenty of books for Potions; and perhaps for Dark Arts too... I think the floor would also be carpeted

like his home in Spinners End, I also think that he wouldnt have any pictures in the room either. A dark atmosphere that seems ancient...

I always pictured him having comfortable furniture in the sitting room: a medium sized, plush couch with a matching chair, both earthier browns. A big, dark wood corner desk (walnut or ebony), a large, matching bookcase against one wall and matching side table, just big enough for one lamp. A lighter hard wood floor (like mahogany or rosewood), but there's a small, soft, ethnic (like Spanish or African) rug in front of fire place. Two lamps - the small one on the table, and a standing one on the corner near the desk - both with a deep brown/gold cover and the drapes match them. The walls are a soft, deep gold and the trim is the same color as the wooden furniture. There's two mig(ger) windows on either side of the fireplace.

His bedroom has a huge king-sized, four poster bed, a shade lighter than the floor in the sitting room (so like cherry, or oak), with squashy white or tan carpet. The walls are a soft beige. There's a single night table, a small writing desk with a bookshelf, and a wardrobe, all cherry or oak wood, and the trim matches. There's an over head light. There's a small(er) window behind the bed.

The bathroom has all ivory colored items, except a small silver medicine cabinet above the sink that matches the faucets and handles. The walls are a soft blue/green, and the tiled floor is a light blue.

The kitchen is tiny. There's a small, round, acacia wood table (it doesn't have that "wood" look to it) and three matching chairs. The counter tops and cabinets are ebony wood. The refrigerator is a dark, metallic silver, to match the sink faucet. The walls are a dark brown, with a beige trim. There's a small(er) window above the sink, and an overhead light.

I envision it having a large walking fire place with two victorion style chairs on either side and a round table between them. Where he sits to read all the thousands of books on the shelves on the walls. Maybe even a lounger couch off to the side. A large oak desk in a corner to grade papers when he didn't want to stay in his office.
As you go farther into his chambers is a large poster heavy oak bed. All very masculine, heavy design furniture and colors somber. Though it would be dark lite by oil lamps, and candles, on multi rod-iron candle holders.
Of course an area set up as a small potions lab. With stores of specialty potions.
In the HBP we saw he has several bird cages as shown in the deleted scene and a balcony.
Everything accessible, useful, and rather simple. No extras, bland.
I figure a large rod-iron bath tub. Books would be found there also. No luxuries. Other than crystal wine decanter, scotch, and brandy with matching glasses in setting area at the fire place.
All Male, but classy and as a gentlemans quarters.

I picture his room being rather minimalistic in design. There's a fireplace, for sure, but I don't see much else in the way of furniture beyond a bed and nightstand. The space is definitely a room where he can decompress. The sheets, etc., are neutral in color. The scent is fresh, like outdoors, but not the laundry product idea of fresh. Not the most welcoming place, but not intimidating either.

I think his quarters at Hogwarts would be just as spartan as his home in Spinner's End. Very utilitarian, really. Table, chair, bed, candles, shelves full of books, nothing by way of what the majority of us would call "comfort".
