Does this village have any colonial features? The house has too much concrete and nothing to warm it up. Use natural wood hand-made railings...not painted. Balance the railings. Upper railings and lower railings are completely different. They should be taller...a meter high upstairs. Do you have to leave the upper columns by the bedrooms exposed? Bring the brick wall between them forward so the columns are inside the house. Divide the casement windows with 4 panes.

@sooz001 - Top frame weather shade is same as bottom one. Attaching new pic for better view. Mostly, i will have to use wooden shutters and extend the weather-shade, may be using some stone or RCC.

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.

I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.
