Good fences make good neighbors.
–proverb
No, they won’t literally make your home bigger.
It’ll just feel that way, especially if you have kids.
What am I referring to?
Solid core doors.
About $150 more than their hollow counterparts, solid doors are the cheapest way I know to make a home feel more private — with the possible exception of ear plugs.
Solid doors also are a big hit with prospective Buyers, who (correctly) associate them with quality construction.
P.S.: My favorite piece of home technology? Eye hook locks for 89 cents that keep my office and master bedroom off-limits.
