Thanks gentlemen I appreciate the advice.
I've gone for roller shutter doors due to the height I need to get a 4x4 in with roof rack and kit etc (2.7meters)
Up and over doors at this size are hard to come by.
The not very secure plastic roof is a weakness I must admit but it's 3 meters high...
Hi all
I'm completely uneducated in civil engineering of any sort so please forgive my ignorance.
I'm having a large garage built with doors measuring 2.7 meters wide and 2.7 meters high, with roller shutter doors fitted.
The lintels the builder has fitted are concrete pre stressed 75mm...
