People make decorative changes to listed buildings all the time. Grade two star and grade one listings are more restrictive than grade 2 and often exclude extensions and alterations that would be possible with most other homes. Grade two buildings (and houses in conservation areas) have article 4 directions that require routine works such as replacing windows to have permission. This is to maintain the character of the streetscape and the historical interest of the building. These regulations may also exclude you putting a kitchen into a front room as this is not expected to be seen from the road. Likewise you would be unable to vent your boiler flue through the front of the building. Restrictions are designed to protect the historical interest of the building but not to freeze it in time so people can't enjoy modern conveniences and decorating decisions.

I think the final outcome beautifully balances the proportions of the property and adds so much character. Well done!
