Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.

A few suggestions based upon your lower photo, the fourth I guess. a. If you had the wall built, ask the guys that built it to perform your wishes. If it came with the house, call the former owner, whose name is on your deed. b. If the former suggestion is a dead end, let's analyze before we plan. You want to have a space for cooking and dining outdoors. This is such a beautiful yard, it does not deserve a portable BBQ unit exposed when not on fire, so put it in the garage as soon as it is cool. If you are going full hog for a builtin BBQ facility, perhaps it can be built against an existing wall, and just the dining area then needs the increased space. A 6' wide round table, requires about 12-14' for itself and the surrounding chairs and service area. Will you be happy with only a 15' or even a 20' section of wall moved? c. Remove the plants from the area that you plan to usurp, and about 5' beyond, and rent a sod cutter to remove all of the lawn from the vehicle entry point to the lower curved wall, by the palm, and stockpile it in shade, if possible. d. Have the contractor saw a vertical cut in the wall at the points of removal. Measure the distance of the plant bed to back wall. Cut the front bed wall that is to be removed with two sections of that overall bed dimention, so they can be placed as end walls for the two sections of bed that are no longer continuous. e. Have the contractor dig up the wall, and cut the two pieces to remain so they are free of the wall to be dumped. He will remove the existing soil from the bed. Modify any irrigation that exists, and then install the two wall slabs to their new duty locations, attach them to the remaining walls, backfill and replant as required.. f. The next step is to cultivate the compaced earth in the lawn area, rake it and resod. If the dining/BBQ areas are to be a dining terrace, you might wait until the sod is reestablished, say another month, before initiating that construction, as you don't want the sod to remain in a pile for long, or you will have to buy new. If it is to be a flagstone terrace, you can have that material delivered and stockpiled where the bed used to be, while the wall crew is just leaving. Will that fill your need. Give this post to the contractor so he can take measurements, and provide you an estimate overnight. Summer cookouts have already begun. Looks like we will miss the 4th of July bash.

For the living room, the focus should be the balcony area. So flipping the couch to face the wall and not the dining table will help. Kind of like this pic. Even if you already have the sectional that is in the diagram, you should be able to flip it. In fact a sectional would probably work better than the couch in this pic. I also really don't like the style of this pic, but it showed what I meant, For the girls' room: No matter which bedroom you choose, you should maximize floor space so that they have the biggest play space possible in their room (as they get older you can add desks for school work and such). To get this space, I would give them bunk beds. This configuration gives them an open feel and more storage, essential for girls. You posted two different kitchen designs. This makes it hard to give you advice. I agree with other posts that your sink should be away from the wall. This allows you to have stuff to the left of you (drying dishes in my house), while you wash vegetables on the right of the sink. You need the same space on both sides of the stove, also. At least 24 inches on both sides is good. 36 is better, though. The first design has a nice little countertop space that adds a place for your daughters a space to sit a watch/ talk to you while you're in the kitchen. When they added this to the first design, you lost cabinets on the other wall. This is bad, as the space is already storage limited. Try making the rounded countertop bump out into the living space more. If you play with the shape, you could make it work without losing the cabinets on the other side. It doesn't have to be rectangular or a perfect circle. You can see how this one isn't confined to the floor plan of the kitchen. I think this is what you would need to do to make it the most functional.

The recommended fit around a DR table is 24" larger on all sides for the chairs. You won't have that on the 6'8" side. I'm thinking the rug is going to be too small for the room 8x10 or even 9x12 would have been a better choice.
