If you're shopping around for homes one of the best ways to experience the floor plan of a home before you buy it is to walk through the developer's model homes before hand. One of the easiest mistakes is to get sold on the upgrades that a home stager and contractors have upsold the model on! Try and strip away the gorgeous finishes, the upgraded carpet, color coordinated wallpaper and drapery and focus on the layout and flow of the rooms. This will help you make an informed decision when choosing a floor plan.
This idea was put forward by our first architect for consideration. The idea is to take the outline of the garage (original and new) on the east side and use this as a footprint to construct two new 'houses' to either side of the current house.
