I'd suggest a shallow bench underneath the window and flank the windows with a base cabinet on one side and a desk on the other. Then open book shelves above the base cabinet and desk. I can't tell what the dark wall is on the one end. The steps need to curve from the door to the wall. A smallish sofa would be great for viewing a flat screne TV and a square table and 3 chairs up against the dark wall would be a great place for puzzles and games. Put a pendant over the table.

Mustafa, my apologies for the delayed response! I've been thinking about your dilemma and this is what I've come up with. I'd make the most of the vertical space in the room so that you allow yourself maximum square footage for counter work space. If you're able to, I would suggest putting the refrigerator on the opposite wall (where the tall storage unit is in the sketch). Something similar to this:

What kind of square footage are you working in? How would you like to use the space? I pulled a few ideas to get started, but I would love to know more about what kind of space you're trying to create. Outdoor garden: Entertaining and eating: Lounge:

I strongly second One Plan's idea about looking for another architect. If this one is not motivated, all the fame in the world is not going to help. An alternative approach to finding an architect is to find some good contractors who have built things you like. Ask them for architects' names. Make sure they work in your price range. In the meantime, you can find out from your local building department what the set back and height restrictions are. Are you required to build parking areas or garage space, what kind of airspace restrictions do you have for neighbors' views and sunlight, that kind of thing. Often this stuff is on city websites or handouts at the office.
