There is an app called social print where you can get your pictures made into a poster or book or framed. I have had pictures printed from them and they are great quality. My mum is going to get her travel pictures done in a poster form, which they can also frame for you as well.

We have a collage of 19 prints, originals and photos on our space of about 7 metres width. There's a mix of canvas prints, black frames and champagne (not gold or silver but somewhere in between!) it sounds like it could be bloody awful but in the reality of things it looks great! Only two sets of canvas prints are the same size, two smaller B/W old photos while the other two are larger coloured ones. Some are landscape while the rest are portrait shape, bigger and smaller they all work together to make one oversize grouping which was not planned but plonked according to instinct ;-)

Thanks for the great comments! We love our steel frame construction method - it takes the stress and hassle out of building.

extra fascia depth would be dependent on how much you want to spend on extra labour by not using standard steel fascia (which is only about 185mm wide) with all the standard fixings ..A carpenter or plumber should be able to make a wide substitute out of sheets of ribbed colorbond steel and the rest should be standard timber framing and soffit linings but check wit a carpenter or roofer about what you want to achieve (why does it need to be 40cm wide??) and there may be a very simple alternative available
