If you have the room, be sure to put a trash pullout at both sinks; if you cannot fit 2 (and I couldn't), consider putting it at the prep sink. Yes, during cleanup the trash gets used...but I'm prepping more often & for longer periods than cleanup so it would have been better to have it in the prep area.

Base Cabinets: Rather than pullout shelves (a.k.a., roll out trays (ROTS)) behind doors, consider mostly drawers. Drawers require one motion to open/close...pull the drawer open/push it closed. ROTS's OTOH, require you to open the door(s) and pullout the shelf, then push the shelf back in and close the door(s)...but the door(s) must be fully open to pull out the shelves and you cannot close the door(s) until the shelves are completely back inside.

Full-extension, Soft-close Drawers: Full-extension drawers (pull out all the way) are a must. Soft-close is a luxury that is well worth the extra you pay in many cabinet lines. Soft close drawers (and doors) only need a gentle shove to close...a couple of inches before they close they are stopped and very gently pulled completely in. Probably the most well-know vendor of soft-close drawers/hinges is Blumotion (Blum hardware).

Design: When designing your kitchen, think of and design around the various zones in your kitchen. The "work triangle" while it still has some validity, has been somewhat superseded by "zones". Storage zone, prep zone, cooking zone, serving zone, cleanup zone; then there are the "centers" beverage center, snack center, message center, baking center, etc.

Gadgets/Neat Ideas:

• Tapmaster
• NeverMT
• Foot Pedal for trash pullouts
• Airswitch
• Soft-close hinges & drawer glides
• piano hinges to utilize the filler space b/w the top of the refrigerator & cabinet above.
• 4" Broom closets
• Filler Pullouts to utilize the often necessary filler (3", 6", 9")--both base & wall
• Windows down to the counter--both traditional/straight and bays and bows

Depending on the layout a large fridge works nicely, or sometimes smaller ones, placed appropriately, can work better. In our kitchen we have the Electrolux All-Fridge and All-Freezer units...a set (one of each) near the cooking/baking areas and across from the pantry, and an extra fridge by the eating area, next to where we keep breakfast, sandwich, and snack items. That works better, the way we work and the way our room is arranged, than it would for us to have 1 bigger one. The price of the Electrolux units made that possible, since the larger than standard refrigerators are pretty pricey.

But, do read that "Read me" thread Buehl linked, and let us know more about your family, your needs, and your space. Can you post a floorplan of the space and it's surrounding rooms?
