If you are referring to a site or a place on how to fabricate them I can't help you. But if you need any tips on installing them you can try www.hometime.com/projects/howto/kitchen/pc2kit06.htm .
You should also consider going to Reno-Depot (Eurofab) or Home Depot (Mill's Pride) for some general ideas on kitchen layout diagrams. They are pre-fabricated but offer a complete list of their cabinets and dimensions for the floor & wall mounted cabinets! You can also try the 3Droom designer on www.bobvila.com for a more realistic viewing of what your kitchen may look like
