Renumber to 10.x.x.x /16 ranges 😉
Use the second octet for assinging the "location"
As example 10.10.x.x/16 for the home and 10.20.x.x/16 for the garden office.
That way you can use the same vlan's on both sides with just a different second octet.
Combining the 3rd octet with the vlan is smart, give you easy overview but using it with the 192.168 prefix limits your options when you want to expand.
This way i'm doing the designs of greenfield or renumbering setups to keep it flexible in the future.
