Minimalist Masculine Bedroom and Den

Minimalist Masculine Bedroom and Den

I'm in the process of starting a new building. I have a complete set of drawings and living space layout but need help with making the best use of spaces.

I have compiled several photos for ideas of what I want but need help making it all work together with my open floor plan. Also, because my ceiling follows the roof line, I have very tall walls with a lot of open space above kitchen cabinets and other areas.

I'm also a car guy, mechanical engineer and stargazer and want to tie those elements in.

Thanks,
Justin
