    Hi, I'd be very grateful for any advice on a project I'm contemplating...

    I've got a detached single garage built in the late 1920's with solid 9 inch walls and a pitched slated roof. On the opposite wall to the main vehicular entrance there is a personal door opening, the load above being supported by two timber lintels. I want to widen this opening to allow a car to pass directly through the garage.

    My question is what would be the best way of spanning the opening? I guess that taking into account end bearings, I'd be looking at a 2700mm lintel. Would two concrete lintels do the job, or is it necessary to use a steel lintel if available - the steel lintels I've looked at have all been for a cavity wall at that length.

    Thanks in advance for your help.

    There's no reason why you can't use a normal beam (UB/UC). I wouldn't know what size but maybe something along the lines of a 203 x 203 UC. What would be the easiest thing would be to see what has been used on the other side and then use that for the rear ;)

    Thanks for that - the original main opening has a timber lintel. I assume it's better to avoid that arrangement?

    You can get "T" shaped lintels for solid 9'' walls that would do. Or as you say 2 concrete lintels 6''x 4'' would also be suitable.
