<human>: Can you give me the gist of the text in a nutshell?

This is my first post here and I'm on mobile so I apologize in advance for bad formatting.

My BF and I have been living together for about 6 months and it's been really great. We rent the master bedroom and half-finished basement space in a house with 2 roommates, who are almost never there.

I say the basement is half finished because it's got yellow painted drywall and bare concrete floor. We laid down some carpet when we moved in and put our desks and computers and a little couch down there to make it a little office/game room. It has a window well that looks out into the back yard, and, though it gets a little cold, we got a space heater and when it's on it's not too bad.

Recently my BF got a new job he really loves and allows him to work from home 3 days a week. But instead of working in the basement with his desk and computer, he wants to put a desk in the bedroom as his "work space." I am really against this as I would like our bedroom to be our bedroom and not his office, and we already have the office downstairs. But he says he can't be productive in the basement since it's cold and ugly and doesn't get good light. We also can't really set him up in the living/dining room because we share that with the roommates.

I've offered to help him paint or decorate the basement to make it better, get a nicer space heater and even one of those "happy lights" but he won't budge. We're really at a stand off here. Am I being unreasonable? I understand how important it is to be comfortable in your workspace but I really think we could make the basement nice instead of taking over our bedroom. Should I just let him set up wherever he needs? Or should he try to make the basement work?

Advice? Thanks in advance
<bot>: My BF works from home now, and wants to set up shop in our bedroom, I want him to try to use our basement office.
