I'm going throigh building control notice procedure to install a new internal door from the house into the garage, I realise this has to be all to 30 mins fire resistance. I've has a few builders come round to look and price the job but not one of them (even the FMB's) seem to know what the rules are re cutting the opening in the corner of the garage through a single skin brick wall that finishes at 1st floor level and is not supoorting joists or anything else above.
The single skin wall I want to put a door in is the end wall of the garage that is adjacent to the internal side (stair) wall which is also single skin brick/block that goes up into the loft and is of course structural.
How far back from the internal corner can a door opening be cut? are there any strict rules here as the new doorway presumably doesn't require a lintel if all the bricks are cut out and a frame above door is built in and plater boarded over.
Garage is internal with a bedroom above at 1st floor level and a toilet at end at ground level. The garage is 900mm lower than house ground floor as house is built on a slope.
It is the internal left end garage wall that I want to cut opening into.
Wall was built as part of main house walls, yes its tied into left stairwell wall to form a corner and also into outside wall to form a T.
There is no load on this wall, I keep telling you, its simply the end of the garage with a toilet room on other side. Ignore the bedroon above as the joists that support this floor are sat in the left and right hand walls.
I trust that you can now make an informed decision..
OK, now I need to know what your qualifications are???
From the stance you have taken I was fully expecting you to be an engineer as you come across so professional with your 'knowt it all' attitude.
Do everyone a favour in future and let then know from the beginning that you don't realy know and are just guessing, it would save a lot of time.
THIS IS AN OPEN FORUM AND AS SUCH ATTRACTS ALL KINDS OF PEOPLE FROM ALL WALKS OF LIFE.
I DO NOT HAVE TO JUSTIFY MY CREDENTIALS TO ACTIVELY AND FREELY PARTICIPATE AND SHARE MY WEALTH OF EXPERIENCE AND OFFER AN OPINION TO OTHER USERS MANY OF WHICH HAVE GRATFULLY TAKEN SOMETHING FROM MY REPLY POSTS AND RESOLVED THERE PARTCULAR PROBLEM.
IF YOU DO NOT GET FROM THE FORUM WHAT YOU REQUIRE THEN SEEK ADVICE DIRECTLY FROM PROFFESIONALS ON THE HIGH STREET.
NO ONE ON THIS FORUM (REMOTE FROM THE PROBLEMS PEOPLE POST)WILL GIVE YOU AN UNEQUIVOCAL ANSWER TO A STRUCTURAL QUESTION FOR OBVIOUS REASONS. (NOTE THE LACK OF REPLY POSTS TO YOUR QUERY).
A STRUCTURAL ENGINEER ON SITE IS ALWAYS THE BEST PERSON TO APPROACH BUT THEN THAT WILL BE A FULL AND FINAL ANSWER AND AN EXPENSIVE ONE TO BOOT.
I quote you "IF GARAGE WALL IS TIED INTO STRUCTUAL WALL TO PROVIDE SUPPORT FOR GARAGE WALL, THEN MAKING A OPENING HERE (IN CORNER) WOULD REQUIRE THAT A SUPPORT PILLAR/BUTTRESS BE BUILT INTO THE NEW OPENING".
So tell me how you can possibly make a statement such as this if you simply don't know, REALLY HELPFUL !!!
