When we, the two of us, added onto our little vacation cabin to make it our full time home, we added over 2000 square feet of living space, over 1000 square feet of cellar and an attached two car garage. Actually what we added was a lot of underutilized overhead. The space has to be cleaned, maintained, heated, paid for and is taxed forever.
Recently we have visited two different friends who have purchased in recent years new homes. They are large spacious homes, with lots of wasted space and are not very interesting architecturally. They have made the same mistake we did; larger is not necessarily better.
Please think about this and comment if you have fallen into the same trap. More about this trap in a little while.
