Catalina- Model House roof Free 3D model

This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This is an alternate rear roof. It is what the actual house roof looks like at the rear. There is also a revision to the front elevation, which looks more like the actual house as well. Which roof do you think looks better - a gable or a hip? And does the revised front elevation look better as well? This would give me 3 places to put solar collectors. TY Bob
