Thanks for that.
There's a lot of available storage. The double door cupboard above what was designed as a cupboard for a TV set houses some CDs.
I fettled some click together CD racks, for them, there's "one and and half" units in each rack.
My library of sheet music and fake books are stored below. I've a Yamaha Tyros 5 "leccy piano" (they call them, "work stations") against the opposite wall.
The other double cupoard has the same shelf and just one divider below, I added more to separate my music books in this one.
The illuminated cocktail cabinet, with the drop down door that acts as a drinks table, my wife uses to store lots of boxes of her decoupage card making kit.
The wide drawers stick out six inches further than the rest of the unit so can hold a lot of stuff.
I can easily slide everything above the drawer unit forward by that amount, if I choose, if I need to get at all the wiring for the lights and all my audio kit behind it.
The only downside is that at times it can "eat" 240v 15w lamps, one would go out every month or so, but those I'm using now seem to be lasting longer. Mind you if I'm home, they can be on more than twelve hours in the day.
