Single skin wall

Tonyteepeg

We have a bungalow that has been extended.the older part has walls that are solid 180 mm with render making them 230 mm in total . We have been told that lenders will not lend against this wall thickness. A builder has advised us to dry line/insulate the walls to make them acceptable. Is this the correct way to go. Thanks.
Ps there is no damp at present.

What is the 180mm made up of?

An entire single skin house isn't really mortgageable, but you can often get away with it in small areas, but a genuinely single skin brick wall, with imperial bricks would only be 110mm wide. The width of your wall puzzles me a bit.

I've lived in several old houses and 230mm is pretty usual. A brick house without cavity would be 230mm and even early cavity walls would only be about 240mm.

Who looked at your wall and told you it wasn't mortgageable?

I would be surprised if most lenders would even notice.

The extension on the property I just bought has 230mm of brick with render on top. Not a peep from the valuation surveyor.

The wall is concrete block. Either 6" or 7", not too sure which. Estate agent advised us of potential problem.

Ok, I think it's the concrete that's the issue. Drylining or insulating the walls is not going to make a difference to making a concrete built house mortgageable. A "non-standard construction" house will always be a problem until someone completely rebuilds the walls.

Houses like that are worth less than similarly size houses in the same area and, yes, troublesome when it comes to raising finance. There will be a specific name for your type of construction that you could probably google and find out more.

What area do you live in? Have you been there long? I'm guessing you've either been there ages or you bought in cash?

We have been here 20 odd years. Concrete block is pretty standard where we live.

About 20 percent of the UK housing stock has solid brick construction pre WW1 and is 230 mm thick as a rule.

When you say concrete block do you mean concrete or breeze block?

Where do you live? How old is your house?

There is a difference between concrete blocks. Modern houses are built with concrete blocks all day long, but it's the older methods that are troublesome where the concrete was reinforced.
