Hi Marie Claire it would be nice to be two toned in soft almond white and light beige or pale grey possibly. Vaspar are now at B and Q and the paint is amazing if not then dulux out door paints are always good.

I found a pic earlier of a light grey Edwardian house with charcoal windows on houzz as shown. I also found one of the french grey and agree it looks green so I am not doing my house in that either although it does look nice on windows with cream render! Little Greene have some fab colours so maybe a pale but warm grey. Do also try the Dulux heritage colours if you want a period colour

@Roomhe3-by-Room (UK) Ltd thank you for your comment. I did a rough mock up of your suggestions on PPT and the slate tiles and dormer with grey windows makes a dramatic difference. I really like the look of it! The current concrete roof tiles we have are believed to be original from the 1950s when the bungalow was built, and if I have done my research correctly, it has to come to an end of its life span of 50 years so it may be worthwhile to redo the roof too. Would love to opt for slate tiles but have heard these are more expensive than concrete tiles. We don't have a big budget but would like to go for something similar in appearance and durability as slates at a lower cost. Is there something on the market that fits this profile like concrete roof tile in grey slate colour? This is my first building project and knowledge of materials is very limited! Thank you

To get a clear view of what colour your windows and doors are i had a quick google, from the majority of the pictures no one had really painted render other than an off white however they have also mixed white stone and yellow brick so its a bit of a mixed bag. These are two that i thought looked really good.
