Marley Classic Guttering on conservatory...

Hi, I am presently building my own double hipped conservatory on the back of an existing extension (hence why it needs to be double hipped) using a box gutter.
Now the problem is that the conservatory doesnt go the full length of the extension by about 1 metre - so I will have to keep the half round guttering on the extension fascia and also have the gutter box below it.
Both gutters will go around the corner of the extension and I have to 'join' them somehow - would the best way to do this is to have a hopper and have them both join here to go down one downpipe???

Cheers

Thats one solution. Alternatively, if height difference allows then you could continue half round over the box gutter slightly, allowing the half round to discharge into the box gutter.
