We need exact measurements on your floor plan. Also, do you plan to have outlets on the floor to use for lamps for the floating couch?

How high is the ceiling?

Given the size and layout of your living room, a good rule of thumb is to have at least one recessed light for every 4-6 square feet of ceiling space. Based on the dimensions you provided, you could potentially install 9-12 recessed lights in your living room to provide adequate lighting without overwhelming the space.

To avoid a dead zone between the dining room and living room, consider installing a few recessed lights in the ceiling along the shared wall to provide additional lighting in that area. You may also want to consider installing a dimmer switch for the recessed lights to allow for adjustable lighting levels depending on the task at hand.

Here are my suggested locations for downlights. I think you will want ones with a gimble

IMO if yoou have enough lighting layered in a LR you do not needgimbals which often cast weird light on walls and art. If you have specail art pieces then those can be high lighted . I think in a DR 2 pot lights i enough above the buffet 5 light chandelier tells me nothing since IMO all chandeleirs should light the table and most light the ceiling . I think you will have some issues with llighting in the LR 2 floor lamps either side of the FP could help I like arc lamps to get light closer to the middle of the room Most laptops can be used even in dark rooms . The paths for a wheelchair are tricky so make sure every path is the right size . Any more help can only come after you post a to scale floor plan showing every measurement , windows , doorways and in thta kitchen the width of all the walkways too. Using graph paper makes it easier to do scaled drawings . tHe post that here in a comment you need to use jpeg format . Do not start another post on this space you are asking about.

Hi all -- thank you for the comments. I've updated the main post to include measurements on the graphics. The ceilings are 8' high. There is no floor outlet, but that's a great addition to my list.

For what it's worth: Ethan Allen Shelton is the sofa that I'm using - it's got the perfect combination of support, a comfortable arm to lean against for TV watching, etc. and style. It comes in 88" and 98." I'm having it done in a bench seat but keep going back and forth on the length.

I personally would rather have the walk-around space in the room than push a sofa a smidge too large in the space.

Are you sure you want facing sofas? Looks visually cramped to me

I updated the main post, but in case this is easier: I've attached the floor plan with all the dimensions I could think of, and reduced the size of the sofa to the 88" version. To answer some of the other questions - the ceilings are 8' high; I have a large mirror and buffet lamps that I will use on the dining room back wall so am not concerned about light there. And, yes, I do want two parallel sofas. We are both loungers, feet up on the sofa, so it works well for us, especially with the TV mounted over the fireplace.
