Hi, I have on old Victorian Style Town House.
The bathroom is a box on stilts added to the REAR of the property. The bathroom window is clearly visible from the main seafront road. We are in a Conservation area but I understand that changes to the rear of the property is not considered to affect the character of the property.
I am upgrading the interior and my wife wants the window depth reduced by raising the sill or by using a same size frame but with an extra transom at 1/3 up with blanking plate below and glazed above.
Will I need planning permission or Building Regs approval for this?
