Did you mean to add a photo to your question?

I would go with Monument. The house is dark brown so adding some relatively small surfmist elements wouldn’t change the perception of the house. At the photo above the surfmist works well as the roof is visible from the ground and it’s surfmist as well. The brown brick has those dark spots which go well with Monument. The house will look dark but elegant. In order to make the house more cheerful I would invest into adding as much greenery as possible. You might even think about adding couple relatively large pots along your side wall and/ or at the front right. You can also paint the front door any cheerful colour you like.

Everyone has their opinion... I'm saying I don't like it. Others will like it. It's in comments above.

No-one has really asked you your favourite colours , although your suggestion was white and white and off-white and almost white and white and Monument . Was that because its what you want , or because it's what you think might look okay ? Pretty safe ( thats polite wording for boring ) . For the exterior , I'd want to find out more about you . The interior I'd say the same , but a couple of general suggestions . Firstly , that grey on the lower walls has almost violetty tones in some pics -- that would be where I'd go a light tone -- surfmist or similar . But for the 'uppers' of the walls , instead of everything the same , how about a different colour every room , and either wallpaper , or a wallpaper feature wall in each room ? Pastels , stripes , chevrons , monotones -- different paper , different colour tones , different rooms -- plan an overall theme and tone that suits your taste , your furniture , the art , the duvets , the towels you already have . Have some fun , white and grey and monument are what you use to fill in between the fun bits .
