Dad Cave build

This project is a long time coming and I'm really excited to work with somebody on it!!! I'm looking to convert the unfinished side of my basement into a "Dad Cave" --- think of it as a man cave, but also where i can spend time with my son (1yr old). The space is rectangular at around 30' x 10' --- which i can send you more detailed dimensions that take into account objects that cannot be moved (ie slop sink, heating system, etc). A few key points about the space: - This is also a working space where i keep my tools - I can add electrical and lighting where needed - The floor is going to be leveled, sealed, then painted - I'll also paint the walls I'm a really bad designer, but below are a few features of the room I'd like to have. I'm hoping whoever i work with they will bring many more ideas to the space: - Fish tank - I will have a 4' x 2' planted tank setup and I am open to additional smaller tanks - Temporary space (3 months a year) for growing seeds into plants -- grow setup is 3' x 2' - Some type of art on the walls (paintings, pictures, 3d metal art) - I love steampunk, science and DIY projects - i use my hands a lot and its important to me the space conveys that - I'd like my son to be able to play and interact with the room -- as he grows older, I'd like to swap out items so its relevant for his age (I do not want plastic baby toys in the room) - I don't necessarily need a minimalist design, but i want this space to be relaxing for me and my son Thank you in advance!
