I am planning to remove an internal wall which is made of concrete blocks. I've checked its not a supporting wall by lifting the floor boards, and its been built between and parallel to the joists. However, from reading previous responses to removing internal walls there is the occasional mention of non load bearing walls providing support/bracing to adjoining walls.
This wall equally divides the ground floor back of the house in two and my main concern is that the wall it is buttressed against (at right angles) is an internal supporting (brick) wall. This wall rises three stories and once the non load bearing wall is removed this supporting wall would be, on the ground floor, 8 metres long and 11 foot high but without any buttressing.
Its also slightly complicated by the fact that the wall I want to remove is not an original wall, it was built in the 1980s and the house dates from 1895. This wall replaced two walls that divided the space into similar sized rooms. However, following removing wall paper it appears that at least one of the original walls was either stud or lath and plaster as there are old screw holes running from floor to ceiling.
Are there any simple checks to discover whether the wall is a bracing wall or is getting it checked out by a structural engineer/surveyor the only way to be sure.
Any advice/comments gratefully received.
