I think I'm with you too, Otaku, on the darker color. Although, perhaps not the purple. We also get a fair amount of natural light down there too for a basement.
For electrical, the basement is divided into 3 sections. A game area, TV area, and an Office area (it's own room). Each area is on its own circuit with 12/2 wiring and a 20amp circuit if I recall correctly. The lights for the entire finished basement are also on their own 15amp circuit and those are planned to be recessed lights utilizing LED bulbs. Electric heat is on 2 appropriate circuits.
From what I understand, it's overkill for a traditional basement, but I'd rather be on the safe side. At first the electrician was going to do the main area on 1 circuit and then I said I wanted it on 2 for all of the power!
For outlets, I just did standard height from the floor. I thought about doing higher mounted ones but I just wasn't sure where things would be. The only consideration was a higher mounted one for a TV but I opted not to as we weren't 100% positive if we were wall mounting or not. With every coax for TV is Cat5e for internet (I know...I should have done Cat6 but I had like 800ft of the stuff already). There are TV/Internet jacks in every area (TV, Game, Office). Also in the place for speaker jacks with conduit going through the wall up to the ceiling so I can wire the basement for speakers. I have the wire...the plan was to do it before the ceiling grid went in...that just never happened. Ideally there will be surround sound in the TV area and speakers for music in the 4 main corners.
Since this original drawing more games have been acquired...hehehe.... Hence the concern about the space with a billiards table. I also need to update it with the Lally columns....stupid things doing their job holding the house up! Psh.. An engineered beam isn't in the budget.
Here it a tentative layout though. The walls are in the correct spots though (closet underneath the stairs).
