Hey thanks Carole, I just found that in a colour chart and it looks really hopeful to me... I think you're onto something! It just might be the one... Thanks so much for the tip, I'm off to get a sample pot!

Definitely the grey, the lighter limestone colour is too yellow for your house!

Are you able to post some pictures? Lots of clever people can then help or give ideas.

guess you would have completed the update by now but just in case, They built great houses in the 70"s, a lot had concrete tiled roofs, have them checked and if sound paint them grey along with gutter and barge boards as you suggested but please do a soft grey otherwise it will look too top heavy, down pipes same colour as bricks (photo of soft grey roof) Paint garage doors same as brick colour minus the stripe, Front entrance update would help, does this open into a small foyer Railing, windows painted, I prefer black for this, I have attached a photo of a house that the owners had the roof painted, they painted all the metal windows themselves, said it was easy. Paving in front of entrance, this photo shows they used white pebbles and pavers with a small screen, plus a new hedge. similar entrance doors to these let in much needed light as these houses can be quite dark
