Character plus ... a leaking conservatory

I've been keeping an eye on properties I might like to buy. One of my saves searches brought me a house in Kelston with the caption "Heaps of potential -character plus".

The listing touts the proximity to bus stops, schools and shops, and suggests a bit of paint and new carpet will transform this home.

It also mentions that there is a "a cosy conservatory off the kitchen (possibly a little unpermitted work here but at the price you may not care)."

The listing includes a picture of it:

Maybe it isn't that bad. Plenty of people do great work without getting the expensive council permits .... right?

This picture gives a better view of the conservatory:

Possibly unpermitted? Only possibly? I know the various city councils were a bit shoddy about certifying work a decade ago (and hence the leaky homes problem), but how can anyone imagine Waitakere City Council could give a permit to a conservatory that requires a tarp to keep the rain out and a bucket to catch the leaks?

I don't mind redecorating, but fixing something like that and getting retrospective consent isn't part of my plans. At least they're up front about it I guess.
