If you were to use a curb mounted type of skylite from say Insuladome on Long Island you could use a 30" width. I do not sell skylites any longer but when i did i most always preferred and had better luck selling the curb mounted type as opposed to the Roof Window style like a Velux.And that really became an issue with me when HD started selling them cheaper than I could buy them from Velux themselves(Velux does also make a Curb Mounted unit since they purchased Thermo-Vu) but i still would not buy them from a box store

A skylight will only provide light during the day , they cost quite a lot to have installed properly . I would add better overall lighting , what you have now sucks get some pots with LEDS not warm but in the 5000 range . A counter depth fridge will make the space feel more open. I would have glass door cabinets for the uppers with lighting inside too

Check with the manufacturer. Often the curbs can be made from 2x4's or 2x6's. Most builders/roofers make them from 2x6's because the flashing doesn't need to be trimmed on site. If it's of no consequence to the finished product, then 2x6's are more convenient. Yours look to be made from 2x6's and if you check with the manufacturer, you might be able to reduce the height 2" by redoing them with 2x4's. It's not an easy job to change them out to 2x4's after everything is in place, but if it's important to you, then it is quite doable. Those skylights are very blocky, angular, and high profile as well. Another product, like a Velux skylight, has a much lower profile and sits lower on the curb (worthy's photo in a post above) and that might be another option for you to consider. (If you change over to Velux, you'll also have to change flashing to retain the manufacturer's installation warranty, but with a 2x4 curb and the lower profile skylight, I'm guessing you'll be able to reduce the height above the roof by approximately 3".) If you're intending to replace the make of the skylight or the type of skylight with deck mount, make sure the inside curb/rough opening dimensions are the same or you might be adding significantly to the cost in unexpected ways with framing changes. In terms of positioning: I might be mis-interpreting the photo, but unless there are other considerations with obstructions, etc., usually the best location for skylights is in a position favoring the center or dark part of the room to complement the light from the windows. It's what skylights do best: bringing light into the center of the room. Hindsight is 20:20 right? Having three positioned near your windows won't do a lot for you in comparison to the two that you say are already positioned back further in the room. Without seeing the overall design, I suspect my choice likely would have favored just two larger skylights back towards the center/rear of the room negating the need for three 2x2 skylights at the windows. If you do refit the skylights, it might be worth considering repositioning some or all of them back up the roof a ways to bring light into the center of the room. Yes, and the installers didn't take their time with the flashing. Just got sloppy. If they are re-doing the curbs, they may have to re-order some flashing and make sure they take their time with the next install to get the flashing seated tight and trim as necessary so that it doesn't protrude above the curbs and get flexed by the skylight and/or the mounting screws when it is in position. If you choose to retain these skylights, then fixing the flashing issue shouldn't take them long at all and you should expect it. Personally, all else being equal, I prefer to recommend curb mount skylights. They take longer and are more involved to install and drywall on the inside. But the trade-off is that at some stage, homeowners are going to need a new roof. In my experience, the majority of roofers are far more comfortable reinstalling a roof around an existing curb mount skylight as opposed to a deck mount skylight. There's less room for them to screw up and they usually have the materials on hand to make flashing repairs/replacements. Deck mount skylights require that someone on the roofing team reads and becomes familiar with the installation instructions and the chances of that occurring are somewhere between slim and none, and the materials necessary for repair are not necessarily in the roofers' on-site toolkit. Roofing crews that know what they are doing around skylights are worth their weight in gold.

Two more with an island but nothing along the bottom wall (the only way an island could possibly work). The island is only 30" deep, which may be enough. It does give you around 9" from the sink (not faucet) and the back counter edge. You can't go any deeper b/c you need the aisle width on the working side of the island and at least 36" for the walkway b/w the island and bottom wall. I would have preferred another 3" on the work aisle, but 45" is probably doable. The advantage of this layout is that it gives you another prep area to the left of the range for when someone is helping you in the Kitchen (your kids, for example, when they start learning to cook). I'll be honest, while I'm not a big fan of cleanup zones in the island, the additional prep zone is very appealing b/c of the ages of your children (at the age to start helping out). In your favor is that the island is far from the "Living Room" and doesn't face an entry where dirty dishes might be an issue/on display. .
