Well it would help if you would post images of the complete room so we can make recommendations.

Post the pics in a comment here wait until the pics are no longer grayed before submit

A strong living room design starts with identifying the primary purpose of the space. Whether it’s meant for entertaining guests, relaxing with family, or serving as a multi-functional area, the layout should support those activities. Furniture placement should anchor the room around a focal point such as a fireplace, large window, or media wall without forcing everything against the walls. Proportion and spacing are critical.

Leaving adequate breathing room between furniture pieces improves comfort and makes the room feel more open. Thoughtful use of rugs, lighting, and accent elements helps visually define zones, especially in open-plan layouts. Rather than filling the room quickly, it’s better to build the design gradually, ensuring each element contributes to a cohesive and comfortable environment.

will you be painting the room? the built ins?

Do you have existing furniture? Do you have room for an L shaped sofa? or is it merely for comfort/lounging? How many people do you need to seat comfortably on a regular basis?

Here are the pictures

We do not plan on painting the built-in. Its a family living area and where we'll frequently entertain guests.

I think a gray, beige, or brown sofa would suit your living room. Furniture in these shades would look stylish

Do you like the built ins? I personally would want to get rid of them, grt Tue tv off the fireplace and then design.
