Considering exactly where your furniture will fit in your new home is a must. The size of a room can be deceiving. Just because a room is large, doesn’t mean it will accommodate your current furniture. I would suggest that you measure your furniture and pencil in your furniture on graph paper. Decide where plugs and switches will need to be located. Some people simply have large pieces of furniture. It will come down to selling your furniture or paying to redesign a house plan, plus paying for the added square footage. We recently designed and built a home for an Air Force couple. They have lived in many parts of the World and have accumulated a lot of interesting pieces of furniture. I’m sure many of you have friends who have served in the military and have a plethora of styles of furniture.
This couple has some very large furniture and required a custom-designed home. To them, it was worth the price because of the memories that furniture gave them. It is always less money to buy stock home plans, but sometimes they will need some adjusting to accommodate your furniture unless you are willing to part with it.
