I had to just add some stuff up to help some bids get put in, and I thought I would share.
The castle has a total of 10147 square feet conditioned above grade that you can stand on. I phrase it like that because we have some double height ceilings and some people count that as double square footage, but you can’t stand on air, so I don’t. Additionally there are 2632 partially finished partially conditioned basement square feet, 1035 unconditioned basement square feet. Then there is an attached unfinished unconditioned bare concrete floor/wall/ceiling patio basement (an artifact of the bedrock, slope, and position of the house) essentially a parking garage, that is 3544 square feet.
We will have 9 bathrooms. It seems like a lot, what governed our decisions on bathroom placement was making sure one was accessible without you having to walk halfway across the house or up or down a stair. You have to plan for things like the pool, do you want people to have to walk, dripping wet, across the house to use the bathroom or do you add one near the door to the pool? Many of these bathrooms are just half baths though. There will be 8 bedrooms, though not all of them will be used as such.
There will be a total of ~179 light fixtures, including things like fans and garage door openers. The kitchen is 314 square feet, which is just 3% of the conditioned total, and even less of the gross total.
Our total acreage is 20, and most of that is wooded forest.
