3D drawing/renderings of houses

Industry: Business
Design details: We need a series drawings completed that are realistic, not like cartoons!
They are all sections of houses showing rooms, furniture and services ie air conditioning, boilers, pipework etc.

You need to replicate what is attached, but to look much better visually and include a background ie grass, sky etc....

Please see attached drawing to give an example of what is required
Target audience: Owners of houses
Ideas for the visual style: Realistic, rendered well
Things to avoid: Not to look like a cartoon
Extra notes: Please include samples of house or building that you have drawn/rendered before or send me a link to your website.
