Yes actually it was the whole house I was referring to. I have purged unused components....just found out a few of tips which were to :

1. Use wire frame mode when rotating/editing a large object as this works much quicker.
2. Use smaller bitmaps/jpegs for materials when rendering.
3. Use classes (cant believe I didnt use this before!).

My money is the pc is running out of ram.
How much ram do you have?
If you have more than 4gb then i would suggest to do the LAA thingie (large addres aware).
You can download it from here. (http://www.techpowerup.com/forums/showthread.php?t=112556)
You can try too "cook" your light engines (IR LC or QM) for separated.
30 minutes is NOT that much time.
I used to render on a E8400, final renders took up to 3 hrs.

Hey Thanks! will check that out.

@junior-architect if it's not too late, post the model or section you want to render on the site and maybe some of us can have a look and try and give some tips.

My model is about 90 mb lol! how do i decrease the fil size...Rendering Time is taking ages (about 30 mins per render) most times it takes ages to respond of even rotate when not rendering.

Here are the details under Model info - Statistics -

Edges----------------------1715497
Faces----------------------717820
Component Instances--------37201
Guide Points---------------31
Groups---------------------37141
Component Definitions------165
Layers----------------------27
Materials-------------------345

Im guessing I have to decrease Edges and Faces to increase the Rendering speed.

Is there a way to do this?

Oh sorry I am using Vray 1.49.01

Thanks for all your help here is my latest render...what do you all think? be as honest as possible please, constructive criticism welcomed!

Thanks for all your help.

@ stefanq - could you send it again please...im getting a corrupt file - thanks

@ bhbarchitects - WOW thats the type of render i am looking to achieve! Is the furniture rendered in VRay or Added via Photoshop? Oh and excuse my basic knowledge, on the camera drop-down which do i change to between 30-60?

@ valerostudio - Yes i did set it to invisible but i just realised "Show GI only" was selected also...silly mistake...

Thanks will check up on those bitmaps...also i think the problem was in some components downloaded from the sketch up warehouse. Once i deleted these, sketch up was rendering perfectly...(well a little slow but rendering nevertheless).
