Please forgive my comments if they are not applicable as it is difficult to read the plans from my computer and I am unable to enlarge them. I live in America so I recognize the difference in cultures but just a few things you may want to consider: The kitchen appears to have windows that have a view to nothing significant, whereas if it was on the opposite side of the house, the views would be of the lovely garden. Also, the kitchen appears a distance from the garage, where the grocery/shopping items would be carried in from. I believe a better location would be somewhere closer to the garage with easier access to transport items. Another consideration is the idea we call a "Great Room"--whereby the kitchen is open & next to the living room. This is a beautiful layout conducive to ongoing conversation with guests & family members alike and much prefered to cooking in a room alone, separated from loved ones. Since the house is multiple levels, I would recommend placing the laundry room (washer/dryer) on the level with the most bedrooms. This allows for ease of accessibility vs. up/down multiple stairs to transport dirty/clean clothes. Best wishes to you! I think you are wise in soliciting suggestions/input now as there are many changes I still wish I would have made. :)

You could also bring in some texture with bamboo sticks or decorative branches and help balance a bit the height of your room with small scale furniture. Spray paint them if you find the perfect size and shape but they aren't the color that you need. Ikea carries white decorative stalks for a very good price. the ones in the 1st picture hold well with small kids around and you don't need a vase for them. there are washi paper or crinkly paper floor lamps with a soft beautifully diffused glow For a budget friendly version check ikea or target http://www.ikea.com/us/en/catalog/products/80028552/

Mohammad. I understand your program. You may be lost in the details at the moment. Please do follow and trust the advice given here by all these people. You are about to embark on a reasonably expensive journey. Get professional help with someone who you can sit down at a table and brainstorm with them your ideas and intentions. There are Architects and there are professional building designers who are members of the American Institute of Building Design (AIBD) who are well versed in projects such as yours. I personally love a design challenge. After 38 years designing homes and special use buildings I enjoy this type of challenge the most. I am in Ohio and may not be close to where you are but I am sure with a little investigation you will find the best design professional for you.
