Speciality Item - King Loft

I stumbled on this website some months ago after trying to find a cost effective way to get some furniture for our home. After looking over the post, pictures, and plans it inspired me and I feel like I could complete my entire home in durable cost effective furniture and have fun doing it. We work from home and would like to convert our bedroom into a home office utilizing the space as wisely as possible. This is what we have and need to accommodate...a king sized bed and two individual semi private work spaces lots of light, bookshelves and storage. What I was thinking is doing a king loft creating extra support directly down the middle and putting plywood on both sides to create wall. Then building a desk area on both sides of that wall with custom storage and set up for optimal efficiency. I have skimmed several plans on this site and others and the common thing between all of them especially with using a king loft is the ability to provide optimal support. Both the front of the bed and side and the entire length via the middle of the bed would have extra support. Any suggestions on if this would be sufficient support or should there be other places with additional support? also any thoughts on height I am a bit confused on how to break down the height so that the top is comfortable enough for two adults to sit up in the bed atop but also enough for desk area at the bottom.
