I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

It looks like a loft. Can't really see room. Paint a soft gray. Hang panels on window go to the ceiling in a print. Try a contemporary look like black and white chevron. If you can't hide pipes just go with them. Paint them the same color of area. You have a view direct all furn to capture that. Big art in bold colors to being in color and interest. Ikea has great things. Think scale on furn. Will a TV go here? What are floors if wood or tile. Use a area rug in front of sofa area. Use glass top on tables to make room appear bigger. Low modern furn in light colors will work best. Paint all trim and doors white. Use brush nickel for hardware.

A good beginning would be to replace the walkway up to the house. A new brick walkway or stamped concrete in the same color as the brick on the house will pull all of the elements of the exterior of your home together. I made my walkway 3 feet wide with 2 feet beds on each side of the walkway in stamped concrete. Create the walkway at a distance from the house in an organic natural flowing pattern up to the house with planting beds flowing beside the walkway. Take the brick right up to the from door. Soften the entrance to your home by opening the planting beds up by the house into large organic shapes. That's what I did with my home and it changed it dramatically! It's a lot of work but what a difference!
