With the addition of 
Bon Voyage, I've started designing some vacation homes.  This one is a rustic cabin in a wooded area with fishing access.  It has two stories and a basement, two decks, and two bedrooms.  This is intended for use as a Lake Area vacation home, but can be used as a regular residence.  It sells for around 75,000 simoleons.
Custom Content:Dead leaf ground cover by McTrick at 
McTrick's Place.
Unsigned "moist terrain."  If this is yours, let me know so I can credit you.
Custom walls and floors by Kate and Christine at 
Parsimonious.
Custom objects (except for fridge) by Kate.
Custom old-time fridge by Hed at Southleigh Simdustries.  I can't find a link to this site, but he gives permission to share the object in the object description.  NOTE:  I'm unsure if this fridge will use the "Stock" and "Leftovers" options that came with Seasons.
I have all expansions, but this should be compatible with any.  The pillars I used in the deck came with Bon Voyage.
