Create 3D Model and textureing of room

A room as seen in attached file, I will send you a few OBJ of charachter sizes, they are Poser and scale is small in the other 3D Modling applications. So room needs to be built to scale I have attached a top view of the room to be constructed. We can talk more about details. I also attached a iamge of the type of textures I would like on walls and floor. If circle/oval shape is challenging you can make octegone with flat surfaces. Circle or oval in shape or Octegone shape, windows no gless, walls will need a thickness to them allow for window and door depth. Door ways no doors, they are open one is entrance way the other is large walk out to Balconey. I will need this textured, diffuse and bump maps. Image attached shows style and colors i would like to match as close as you can. Need this done in 7 days
