I hereby send my design proposal to you, I really hope you like it and according to your wishes.
My design maintains the outer walls and roof as the main construction and therefore does not change much. Changes are only found on windows and wall bumps as a new facade freshener. Additions to processed horizontal beam walls adjust your taste / your reference. With the addition of stone elements (gray), and wood (brown) elements a blend of warmth in cool shades.
In the interior changes of the wall reconstruction there is not much demolition but it has a maximum spatial layout, so it will be more efficient in work and cost.
I hope to get the best judgment from you.
Best regards.
