Lots of great tips so far.
One I have not seen yet, relates to internet and telephone cabling. Make sure the best cabling is used and get multiple outlets, so you have the option of rearranging your space.
Some one else mentioned a sound system. Get it hard wired in place.
We have a couple light tubes in our house. They supply an incredible amount of light without glare.
I would hesitate to put a skylight in a closet, you will get fabric fading.
Plan your heating, cooling and humidity controls well.
Your view sounds incredible. I would have a wall of windows too to enjoy it.
Every time I rearrange a room in my house I use graph paper and make little cutouts of the various pieces of furniture I need to place. I switch things around several times with the paper, before putting my back into moving things for real. You could do that and then mark with needs to be in place for each machine, lighting, outlets, chairs etc.
