A question for you Developer

[Danny DeVito]

If you want to put a doorway in a gable wall, is it safe to just knock a hole in it ? Do you put two single cills or a wide cill ? Standard door size. ??

Wherever the brickwork is removed you'll need to support the above. Do you mean lintel?

ha ha ha , well i'm caught sleeping on that one. Yes i mean Lintel. How would you suggest supporting the brick work on the end wall of a bungalow ? I propose to knock a hole into the low garage on the end. The roof frames do not attach to the gable wall. So i have seen builders support the ceiling to allow wall removal but the end wall has nothing on it apart from a small portion of the roof weight.

This seems to be what you are looking for:

Otherwise, the more traditional method of using temporary props until the lintel can bear the load:

All far too involved.

Just take out the bricks you need on one wall first, insert lintel and then do the other. Nothing will fall in such a small (1 metre) opening. It would be impossible for the wall to collapse. Though if there is a window in the wall above then brace it first by framing the opening with 2x4s.

Maybe if you were putting in double doors you would prop it...but not for a simple door opening...especially if a relatively new building with sound mortar.

Worrying, very worrying.

Perhaps getting a builder round to do the job would be best?

Save having to explain to the council/police/dog rescue teams that your house fell down because you asked for advice about knocking big holes in it on a car forum?

You are of course assuming a double-skinned wall...

I find that it's always better to be safe than sorry when it comes to altering the structure of a house

What are you saying??
That forum advice could possibly be wrong / has ever been wrong???

As if.

Knocking big holes in the walls of your house based on googling and asking people on a car forum, what could possibly go wrong...

I guess so, however there are many member on here who have diverse skills and various background trades.

For example, I have used legal advice obtained from the forum to help me out in the past.

I am...but it's even easier on an old 9 inch walled property...remove bricks on one side first, put lintel in, then the other.

if the bond is a 9 inch wall and it is a flemish bond, it won't work. You will need a plank lintel.

Can you post a photo?

I can offer you an opinion of how I'd do it, but the easiest way if you're unsure, is to get a builder to do it.

The best idea so far.

1) Construct a door sized hole.

2) Assemble a house around the newly constructed hole.

Holes in walls are often not straight forward and can/do depend on many factors. Not least type of construction of the wall, type of materials, supported and un-supported loadings.

You may get away with it ;ˆ) but if you fail the results can be expensive and have been known to lead some spectacular collapses.

My ex partner neighbours decided to knock their lounge and dining room into a single lounge diner. They did and were very happy with their work. Unfortunately the under-specced RSJ they used started to twist under the weight of my partners house, which started to move into the neighbours living room. Huge insurance bill followed with years of litigation against builders etc. The final conclusion.. The builder did his own structural calculations. The fag packet he used long since gone could not be used in evidence.

Should be fine. I can't see a problem……

 

[Spinal]

I may be wrong, but that looks like the neighbor has dug a hole too close to the wall... causing what in essence is subsidence...

I'm curious as to how you got this picture of my house ?
