Making the most out of what you have should be your objective when you make improvements to your home. I’ve flipped many homes over the years. Sadly so much of my time and money is spent undoing prior owners’ improvements.
Door hardware (knobs, handles, locks, and latches) should match throughout your home. A hodgepodge of door knobs and hardware and can hurt the value of your home when it comes time to sell. If you live in an older home, find resources for used, matching hardware. If your home has inexpensive door hardware but good quality doors, it may be a sound invenstment to replace all the hardware.
Reuse doors when you are renovating or reconfiguring the layout of your home. It’s often cheaper to use a new door than re-hanging an old door but the old/matching door is always the better option.
Lighting has always been at the forefront of my designs. For best results when rehabbing an older home, use period appropriate fixtures. The cost of replacing old light fixtures ranges from free to costly and having an old fixture rewired is often less expensive than buying a newer one. I love hearing guests admire the “original” lighting in my older home projects.
When replacing light fixtures in a newer home look for fixtures that are an appropriate fit for the style of the home. Installing vintage lighting in a newer (non-vintage inspired) home can create a disconnect that detracts from the value of your home. The best way avoid making a design mistake is to imagine the fixture hanging in an empty room. It’s either complimentary or not.
