2000 sqfoot floor plans 100% in blender Cycles

Room 1 done only a few fire flys in Cycles
Dear all
I am doing a floor plan for 2000 sq foot aprox
below is the floor plan and would like ways to speed up blender on this size model tasks in hand are realistic renders of each room, (using cycles) and a 3d animation walk through, this is the 1st time i have used blender 100% for this type of project, my PC is more than capable i7 3.8ghz, 16gig mem and 2gig GTX 650 ti boost.
but as each room gets built with floors glass walls, desks, etc the system slows down, any way to build or save this in parts and speed things up alittle as the textures are slowing me down
thanks for any tips

Starting to think that i made some Black list ask advice and 0’ zero, nill nothing but a moderator telling me its in the wrong place… is this place like a click within a click group… ?

pointless asking unless your one of the in crowed…
