This opportunity looks interesting to me and I am excited to take this offer.
I can design a good Modern or classic house for you , 2d and 3D models , I see that you need a design for exterior, interior and garden , so I think each part of this design will take few days, so we can take each one partially.
I had a well study of this project and I did a time-frame for it and I think it will take 20 days as the following:
4 days for 2D plans ( house and garden design ) , 6 days for 3D exterior design , 6 days for interior design and 4 days for final touch and make rendering for the project , and about the budget 1400 (including Freelancer fees) euro is a good one for the 3 parts of work which is (interior and exterior and garden).
I had a similar project of this one which was in Turkey and the client was very happy with the outcome as I hope it will be a great experience with you.
I need to know the area of the building which we will build the house on it, and the plan for the area, If there is a design you want something similar to it please feel free to show it to me, and what type of design you are interested in, Modern or Classic whether interior or exterior design.
Also, I should know if there are any questions you want to know and what you imagine for your dream home.
