If you want to build 3D buildings and real world scenes for Architects or Quantity surveyors, then you need to stick to the BIM (Building Information Model) and the CAD (Computer Aided Design) methodologies. 

IFC Architect uses Blender and is building (has built but continues to perfect) a great plugin. 

Highly recommend because this is a very good way to make money: Make a building in 3D, render it.
