Thanks Pragati, it looked to me like some sort of high polished quartz stone and if this was the case there would be a way to hide these joints by filling them with an appropriate material and polish them thereafter. So I guess, the framing-idea with the LED-Strips which pollyannagal mentioned would be a good option. You could also tape some sort of accent-tape over the joints or even just LED-Strips to hide these ugly joints. Cheers Bertram

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.

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.

@Rock Doc: Are you addressing this to me? I haven't actually bought these tiles yet - when I do, I will definitely be going for the handmade ones. They're a work of art and irreplaceable in my opinion. However, there are also screen-printed tiles available in the market in more or less the same patterns; the workmanship is of course different, but you get them cheaper, and they're also more easily available. You could give that a shot. I'd recommend Aakaar Flooring Solutions - they're here on Houzz and are able to provide both the above-mentioned types.
