One of biggest pet peeves regarding home design is wasted space. The average price per square foot of a new home ranges from $105 to $120, according to the US Census Bureau. That means it will cost homebuilders $10,500 to $12,000 dollars for every 100 square feet of wasted space.
With the additional cost, you have to ask if the space is functional. Like that mysterious spot at the top of the stairs - the lounge or study nook - is really maximizing the use of space. Or is it just a costly catchall?
Another pet peeve is one common area. The central living area that grew popular in the nineties is a great example. Home buyers were sold on the vast, open feel of the Great Room, only to realize the terrific upkeep such a space required later. The cathedral ceiling made changing light bulbs a chore and painting a hazard. Not to mention, there was no place to park a girl scout or insurance salesman in a jiff. Guests walked several feet from the entry into a space that refused to wear clutter well. It's no wonder newer floor plans feature multiple living areas to address these issues.
