The first of my articles on house sizes(Small Home-Big Dreams) featured a home with 2200 square feet of heated living space. We explored the strategies which are critical when designing a smaller place to live.
A medium sized home in our office runs between about 3000 square feet and 5000 square feet of heated space. As the size of the home increases, shared spaces are still desirable but are not as critical to the overall perceived spaciousness of the home.
We are able to include more bedrooms as the size increases and/or more single purpose rooms such as a home office, dining room, or sun room. Alternatively, the same rooms found in smaller homes can become larger, either in square footage or volume.
Since we are porch lovers, we feel almost any home can benefit from one or more screen or open porches.
