Main issues, as the Inspector framed them

Whether the steps required by the enforcement notice would restore the character of the building to its former state

What decided it

The character of the listed building has been lawfully changed by prior consent works, and the new metal framed porch and balcony are elegant, harmonious and suit the building's current character better than the original structures, so restoration to exact facsimiles would not restore character but would positively detract from it.

What the Inspector cited
