No need to smash it up, just pop out the glass, slip off the plastic roof and unbolt the frame work. (Of course you could just cut the sides down to the height you like, drop the top rail down and fill the gap with white plastic the same as the lower section) Put up some gutters. Repoint the bricks where it was screwed to the wall and the bit where you’ve removed the flashing. The only bit you may want to farm out is making a nice bespoke set of railings.
:) you’ve right though a builder would probably just smash it to crap and leave bits of glass everywhere. (Not all builders are the same, your experience may be different depending on mileage.)
