A few tips we garnered from this slideshow:
• Hang things on the inside of cabinet doors
• Install and make use of wall-mounted shelves
• Keep your entryway simple but provide a place for everything and everyone's belongings
• Built in seating will provide extra storage underneath (think breakfast nook or window seat in the nursery)
• Built in bookshelves can also make use of tight spaces that would otherwise go unused.
