There are major renovations, such as an addition, or a new bathroom, but short of those major projects, there are many things that every homeowner should consider having done.
Some projects will benefit aging in place family members, such as grab bars in the bathroom, easy access to the front door, and upgraded fixtures to make turning faucets and flushing toilets easy on someone who may have arthritis or poor coordination of the hands.
If you have ever lived in a house with awkward pulls and drawer handles, you will appreciate having hardware that is easy to use, no matter what your age and mobility might be.
Update that bathroom with low-threshold or no-threshold entry, and have it built roomy! Everyone loves a large shower; have moisture proof lights installed over the shower, this makes using the shower much pleasanter!
