I built part of the Guest Bedroom side closet wall. I can't build the whole wall until the chimney is removed (not entirely sure when that will be).
This wall was pretty simple to lay-out and install. I'll be doing the wiring for it probably tomorrow, and that's when I'll go into the attic (so I can do two wires at the same time. Unfortunately, I think this will mean that I'll have no light up there, since I think the circuit for the attic light is the same as the guest bedroom (which will need to be OFF). No worries, I can still run a spot light up there with an extension cord.
Here's the progress so far:
New wall viewed from hallway, looking into guest bedroom:
Footprint view from "L Room" side.
And this is probably the best view I can show for now. The blue lines show where the thin dividing walls will be (these will only be 1 1/2" thick to maximize closet space). The guest room closet will only be about 3 feet wide (39"), but the large "L Room" closet will be a more spacious 54" (I think). Originally I wasn't even going to include a closet for the guest bed, but I figured it would be better to have one, especially if I want to sell the house later on.
The photo is pretty self-explanatory, and it's viewed from the hallway where you'll eventually be facing the built-in.
