Advice on opening up an existing doorway on the ground floor from existing 800mm to 1900mm- internal load bearing wall - spline wall.
Not traditional build - prefab - concrete posts.
Concrete posts approx 400mm apart and 55mm wide, so opening will need to be 2165mm (removal of a further 3 posts necessary), span will be across 6 posts supporting the weight of 4 above.
Lintel size, type and fixing options (obviously the lintel will not be bridged over the posts like normal with brick/blockwork but fixed between them) appreciated including any advice.
One option would be to remove all the lower posts and replace with blockwork but seems excessive!
