Trying to sell my late parents home they have a small conservatory dwarf wall/double glazed/polycarbonate roof porch added 1.5m X 2m. But removed the old existing external door. The work was carried out in April 2002, they did not seek or get building regs permission. The possible buyers have queried this, my response to put back the door would spoil the hall way. And because the work was carried out in 2002 its to late for building regs to be concerned.Is that correct? Understand I would not get building regs anyway. Happy to reduce the sale price to reflect the cost of adding a door. Thank you for reading and replying. Apologies my first post to the forum with a problem, and not some witty comment in the introduction or naafi bar .
