Well this is a new one for me.....and I've been in this design field for 30+ years. Looking at your elevation it appears you're using overlay doors. Meaning the door is outside of the the frame front......I'm guessing your cabinet maker is seeking an elevation without the doors so he can see the frame fronts and get a better look at the configuration and the size of the cabinet units. While I know of many cabinet craftsmen who could take your sketch and run with it.......one thing I always tell young designers is to draw with a thought in your mind as to how is the craftsman or contractor going to build this either in the shop or in the field. I would suggest that you download Google Sketchup (it's free) and easy to learn how to use it. Then I would suggest that you actually build your cabinets piece by piece just as you would if you were building them in the shop Start with the base, add the frame front the sides, back and supports. Then you can add the drawer fronts and cabinet doors...........if you get really into it you could build the actually drawer units individually....... I do this for every custom design home for clients. Cabinet makers love it, because I'm basically giving them a shop drawing, complete with dimensions and I'm confident that design fits in the intended space down to the width of spacers I need. I also give this package to the framing contractor so he know just how exact I expect his framing for the space to be.

With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

A houzz contributor, not too long ago, had made a wine rack out of 4'x4' wooden pallets, that are used in the US to move a load of goods with a fork-lift truck. Perhaps they have them in your country. He cut them in half so they were only two feet deep and stacked them up to high counter height. The wood would be a nice contrast with your concrete, might add a little warmth to the space. cascio.offsite@gmail.com

The best thing you can do on this forum is to ask specific questions so people can give you concrete advice. For example, you might ask 'what art work would look good with this couch?' or something similar so the question is narrow enough for people to answer. There are a lot of people on here who are very into the modern look so you'll get lots of help since your ideabook indicates you're into that. My advice to you is to make your house your own. Go with things you like and that make you happy, and don't make it so matchy-match that it looks like a furniture showroom rather than a house. You want your personality to come through so be sure you add your own personal touches. Good luck.
