What can you not do with a Grade 2 listed building?

What can you not do with Grade 2 listed building in UK, which is Grade II listed most common 92% of listed buildings, you cannot demolish, alter externally, change windows, add extension, paint unpainted stone, or make internal changes affecting character without listed building consent, with fine $10K to $50K and jail up to 2 years for unauthorised work. Grade II listed building, defined as building of special interest, requires listed building consent for any alteration including changing windows from timber to uPVC, adding satellite dish, painting exterior, adding extension, knocking down internal walls, changing fireplaces, and even painting unpainted brick or stone, as it harms heritage character. For example, you cannot replace original timber sash windows with uPVC $10K without consent, you cannot add conservatory $20K without consent, you cannot paint stone facade, and you cannot demolish building. Internal changes like removing original plaster, fireplaces and staircases also need consent if they affect character. So with Grade II listed building you cannot demolish, alter externally, change windows, add extension, paint unpainted surfaces, or make significant internal changes without listed building consent from council and Historic England, requiring heritage statement $1K to $3K and approval $500 fee, otherwise enforcement notice, fine $10K to $50K and requirement to restore original at cost $20K to $50K.
