Hi
I have a single skin brick garage that we want converting into a garden room / office. I have asked for the garage door to be blocked up with an extra block in height all round. The roof will be a flat cold epdm roof, and a new opening will be cut to accommodate french doors. The roof joists run parallel to the new opening and the builder has recommended a 100x150x2400 steel box lintel, there will be a course of commons and a course of aerated blocks above the lintel.
my question is, is the box lintel suitable for a solid external wall, and can it be rendered over as the exterior walls are to be rendered to cover the mismatched bricks and blocks etc.
thanks in advance
