Your life will change.
The house should have some ability to change with it.
Nurseries become children’s rooms. Bedrooms become offices. Offices become guest rooms. Flex rooms become gyms or caregiver spaces.
Technology changes too.
Today’s cabling and smart-home systems will eventually become obsolete.
Accessible utility areas and conduit make replacement easier.
Structural flexibility matters. Could a non-load-bearing wall be removed later? Could stacked closets become an elevator shaft? Could a garage bay someday become conditioned space?
Do not spend a fortune preparing for imaginary futures.
The objective is not prediction.
It is flexibility.
Build a house that can evolve without requiring demolition every time your life changes.
