I made my first MOC (as AFOL) not for this contest but for my wife. Therefore it's 100% buildable, I have already ordered bricks. It is our real house made as much proportionally precise as minifig scale allows. It should be playable so it is divided into groups. Roof and upper floor can be taken off physically. Model is not fullfilled with furniture I made some parts just by different colors on walls (fireplace, bookshelf, sink, fridge, owen etc.). Rooms in upper floor are quite empty as they are in real life - we have just one newborn son staying in black crib :-)
