Indeed very good. From your picture I see brickwork across the front where the garage door would close on to. Is that what I see or are my eyes failing again ?
I ask as that is not how it would be built round here. Round here it would just be shuttered across the front and then the garage floor would be poured and the concrete would form that front edge.
It's a valid question, and I'll try and explain, although it will become more clear in pictures when I get to that part.
The bricks are forming a temporary shutter for the concrete floor, and the top 2 courses are set back into the garage by 2 inches. After the floor is poured, these 2 courses will be removed. The lower courses will remain to provide a good foundation for the driveway where it meets the garage floor. The driveway will be 1 inch lower than the grage floor, which means the garage door will effectively be closing into a rebate, thus preventing any driving rain from entering the garage under the door.
Well that's the plan anyway. It's my design, so it could all go horribly wrong yet!
