shed wall knocking down

[deann3g]

Hi

I have a shed in my garden that is divided into 3 sections and wanting knocking
tgrough into one big shed. the roof is a conctre slab and Im not sure if I will
need to use support such as lintels because roof maybe to heavy.
my shed is 6 meters long and 2.80 m wide and 2.30 high.
I have uploaded some simple drawings to help give a beter idea.

what I want doing is the to knock down the two walls in the middle of the shed
to remove the midlle room so it is one big shed, and I will brick up the doors on the
left and right side of the shed, leaving the middle to gain access.

would I need steel beam, or lintels in the places were i'm going to knock down the wall?
or will I be okay? could some please have a look at the structual calcaultions as i'm not sure where to begin?

any advice is much appericated

thanks

Concrete roofs can be dangerous to work with, it may not need any supporting elements or it may need them where you have removed the walls.
Have you thought about getting rid of it and putting a new roof on?
