How many times have you read the dimensions of a room on a floor plan and then realized your existing furniture doesn't fit like you thought into the finished room? Measure your existing furniture before deciding on final sizes for a home. If you're not sure how large of room you need, measure your existing furniture, tables and walking area to determine how much space you REALLY need in your next floor plan. Add on additional area if you're trying to add space to your next home.
One of the biggest mistakes when choosing the right floor plan is that you forget to picture your own family cooking in the kitchen or you don't take into consideration how your bad back may not like going up 3 flights of stairs throughout the day. Assess your lifestyle before choosing a floor plan. Do you like a single story or multistory home? Do you prefer an open floor plan or are individual rooms with partitions better? Determine what you have become accustomed to in a comfortable home.
