At one point this was known as the 'Pit of Despair.' Windows to a lovely garden covered with moldy curtains and a work bench, a fireplace blocked by a cheap bookcase, junk piled high around abandoned treadmills on a crumbling carpet, musty sofas facing a huge flat-screen, un-insulated walls covered with scuffed (actually nice quality) paneling that was crisscrossed with extension cords and CAT-5 wiring. After emptying it, I'd removed and saved the paneling for later use and removed the ceiling of lath, plaster, and chicken wire, then repairing any dry-rot. After the earthquake sheer-walling and clipping was over, the client wanted it to be an art studio/rental, so industrial extraction fans were installed to vent turpentine and varnish fumes outside. After insulating the walls and ceiling, dry wallers did their thing and contractors installed heating vents and reworked the electrical, I painted the walls a neutral gray, cleaned, repaired, and stained the doors to match the new Murphy bed. The 'closet' originally was the lowest section of a drafty and dusty dumbwaiter leading to the roof, as well as a passage to a low storage area. I built a floor and ceiling within, lined it with the saved paneling, created a magnetically attached hatch, then stained it to match the rest of the woodwork. The fireplace had been stained with the paneling when it was installed originally sometime during the Eisenhower Administration, so I acid washed, then stone sealed it to a mottled pattern. Industrial artist lighting now ringed the room to create an indirect ambient light, as well as a separate artist model spotlight now on the fireplace. Flagstones were industrial glued on the now acid washed and concrete sealed floor, which then was covered with a heavy-duty strip tile. Redwood was placed around the flagstones, as well as the door frames and windows, as I hate particle board in what could be considered damp areas like ground floors. The end result is a warm, comfortable space, as the 'Pit of Despair' is long forgotten.
