I would talk to your council building control about it, pay their fee, get their advice, and make friends with them

Hi all,

Buying a house. Mortgage offer has come through and has one condition
listed:

"Our Solicitor must obtain, and place with the Title Deeds, an
undertaking that the following works will be completed within
six months from the date of the Mortgage Deed: Complete fire
break wall repair. "

Doesn't sound too bad...

From what the surveyor has said (I've not got the report yet) there is a
small part of the wall missing (never built). Is this a case of building
a lightweight concrete block wall up to roof level? I think it's only
a metre or so long at one end, so tapers to nothing at the eaves.

Does it need sealing in anyway to the roof? Can't see how that would work,
and there doesn't seem to be any sealing for the rest of it.

Internet is inclusive. Survey report might have more info I guess, but
I'm not holding my breath!

Any advice?
