I. Work Package Analysis. Your Architectural 3D has an specific outcome, recreate, for architectural proposal the great potential of your land. Using the appropriate tools in architecture and engineering with adherence to the generally accepted techniques will be the key factor to success in your project, even your project doesn't have civil construction actions, you need the model be the more professional from an architectural view, photorealistic from an artistic view, an accurate whit real proposal as possible can be.
II. Design Option. In order to be accurate it will be necessary propose to you an define a 2D model front various angles, from that we would start the modeling process. Base on your dream house.
III. Expected Benefit. The use of some 3D models under high standard of execution to satisfy your expectation, in a compatible file, to compose a technical presentation of the House-potential use of the land-Sell/buy oportunity.
IV. Timescale. This kind of project in regular bases could take 7 to 10 day, but we can reduce the timeline depending the quality of approval of the partial deliveries of products to the client.
V. Major Risk. 1.- The modeler need to received the information immediately, so he will not be sufer a reduce of time which could affect our deadline, or affect the quality of the service. This risk must consider it as a Catastrophic.
VI. The software I recommend. Autocad-Skechtup-Blender. Thank you
