😱 indeed, Victoria. That's how I feel but at the same time, the middle horizontal is a bit high for me. Sigh. Maybe I'll hunt out some neighbours with the original doors and try a few out! Thanks for the link, Joanna. The problem is I've fallen in love with some door knobs, they are an unusual finish and the manufacturer makes matching latches but they only do 60mm and 100mm to the backset. The short one feels a bit tight. The long one is too long, esp if I pair them with thumb turns on the bathroom and toilet doors. I feel so privileged to even have this dilemma but if you are going to spend a lot of money, you want it to be perfect! I shall ponder.

We went for these in pewter. http://www.fromtheanvil.co.uk/handmade-oval-mortice-rim-knob-set-pewter-patina.html will post real pictures once we have painted the doors!

Also a quality electric sockets and switches? I’ll have to go with silver, as I already bought an Original BTC Titan pendant, to be hang over the dining table in the open plan kitchen/dining room.

You can give it a go, the sheds like wickes, screwfix, howdens etc have a limited range of colorfill to choose from, but its not something i've ever had to do so i don't know how well paint adheres to it, i suggested colorfill as it is in a wide range of colours (on line search). Decorators caulk (comes in a tube and applied like silicon with a mastic gun) though is designed to be painted on, so if you have a colour match paint then the caulk might be a better option.
