View Full Version : Building a wall Question

Hi,

Before I ask my question, please bear in mind that I have never built a wall in my life but I've watched people do it and it looks like a job I can handle :alarm: If it doesn't go right, I'm prepared to knock it down and get the pros in so there's no harm in trying myself as it's the only way we learn.

Anyway, I have an extension built onto the back of my house which holds the kitchen and the back door. Connected to the outer kitchen wall is a lean to (conservatory) which consists of 3ft of breeze blocks and on top of that, 3ft of windows with wooden frames and a corrugated plastic roof. What I'd like to do is get rid of the windows and wooden framwork and add another 3ft of breeze blocks to make a 6ft wall of breeze blocks leaving 2 holes for a double glazed window and door, and then add an outer wall of brick

My question is, would I need a foundation to build a 6ft double layered brick wall on the outside of those breeze blocks? Common sense tells me yes but the brick wall will be so close to the already established foundation, I'll have to break through the outer edge of it to extend the foundation for the brick wall.

Can you please enlighten me as I'm gathering as much information as I can before I actually start the job. If you need any pictures, I'll be happy to post a couple.

Thank you in advance.

Giving suggestions on footings is difficult without where you are.

What do you mean by "breeze block"? In many areas that would be a lightweight block made with lightweight aggregate.

Dig down to see if you have a foundation under the block. I you do, how wide is it? If you have a foundation, there may be room to add brick on top of the footing for the block. For a 4" brick veneer, you can get away with 3" of bearing width. You do not need a double thickness if brick unless you want to build a brick privacy wall away from the block wall.

Some pictures will help a great deal.

Thank you for your reply, it's appreciated

Here's a picture of the leanto to give you the basic idea of what I'm after doing.

The breeze block you refer to sounds like the one which was used for the leanto

So I'm after taking away the windows and woodwork and building the breeze blocks upto a little over 6ft, to the height the leanto is at now leaving holes for a double glazed window on one side and a door on the shorter side. Then I'm after building up with regular house bricks on the outside just to make it a little warmer inside as it will be used to extend the kitchen.
I've looked at what I can see of the original foundation and it gives only an inch so am I right in saying that the foundation will need to be extended a little to accomodate the brickwork

Thank you very much for your time and patience.

Oh yes, I'm in the uk so the weather is usually wet with sunny periods if that helps.
