Yes that might look good too. If you have the digital image you could have it printed onto some really nice quality paper too. It should be printed in an ink that doesn't fade. Some print houses specialize in this sort of work.

That colour was f&b stony ground which is actually red based but I think must have some green in, I thought it would work with the terracotta tiles. Something like the lighter shaded white may also work although colours are normally a couple of shades lighter on the exterior. The previous owners of our house painted it farrows cream, I swear it gets more yellow each day! I don’t know anything about the render tbh but I don’t think it needs any maintenance for 20-30 years hence the initial application cost is dearer. I’ve attached this link as I’ve come across a few similar comments (but as I say I don’t know anything about the render and you’re always going to get negative reviews of things). It might be worth creating a separate post on traditional versus through coloured render if you have any concerns? http://www.ebuild.co.uk/topic/15160-traditional-render-v-k-rend/

No? No sideboard? No floor lamp? Perhaps it would be a good idea to have the photos all printed in black and white and on canvas. Fairly large format. Or all in black and white and in silver or white frames. I would personally ignore the different ceiling height and just hang them in a straight line or in a neat group. The centre of the frames should be at about eye level. That means that in a hallway they would hang higher up than in a lounge or dining room.

Mine are in the bottom corner of wall units and top corners of base units. Makes them easier to reach too! I think I prefer the larger knob in your photo but there’s not much difference in the sizes for it to be an issue if you went for the smaller ones.
