Your project description is unclear on your required submissions. However, for my bid I propose to design /submit the floor plans with furniture & equipment layouts, site development plans, 3D modeling & CGI rendering, as well as CAD building elevations & sections.
I worked under several offices for 9 years and now have another 25 years of professional practice as an Architect & Interior Designer and have designed hundreds of residences for Developers, Contractors & Individuals. For your house I would offhand suggest a cathedral-ceiling Living area with picture windows/sliding doors to a landscaped view outside. Further design details will take into consideration your personal requirements, site characteristics and building regulations.
I am new to Freelancers and started entering contests two months ago; as a testament to my varied work skills and ethics I have since then won ten contests, have 3 continuing work arrangements with my contest holders, and have agreed to two more propositions.
If you employ me, I will do my best not only to meet your preferences but also to propose effective & efficient solutions using my expertise.
