All the suggestions above are perfectly good. However, when you have a house that is entirely painted, the options are so endless that it's easy to get stuck. I'd advise either finding photos of comparable homes in colors that you really love, and reproducing a similar palette on your home… or upload a picture of your house to a colorizing site, and play around with various combos. Sherwin Williams has a Color Visualizer that is decent. I don't mind a white house, but feel that the black trim is a bit harsh. On the railing especially- it feels like it is outlining itself too much. Reduce the contrast between the body and the rail and it will enhance the house rather than overwhelm it. You have a lot of choices, so just experiment and go with what resonates with you.

I once saw a gorgeous grey house with a chartreuse door and lots of purple plants in the front of the house. Wouldn't work my (horrible) salmon pink house (one day it will be painted) but since you have the grey might be worth considering?

Your deck will be amazing. It has fantastic form and plenty of architectural interest, it will add enormous benefit to the front facade and street appeal. I love your palette, it is simple and still has point sof interest. MY suggestion would be to use a combination of your exterior colours applied where best to highlight the deck structure and either tie in, or accent against it. Ding all of these things by painting the lower retaining section in the base grey the charcoal colour to continue and blend into the lower floor brickwork, also do this charcoal on the upper deck frame which is also the roof of that entry way. I am trying to say that thick timber which trims the deck. And the slatted section of the stair wall which acts as a breezeway in the light grey- why? Because the open sections of the slats will always appear black as you can see through them to under the satirs, and the light grey slats will stand out and feature that shadow line, perhaps even use liting to further enhance this detail. Lastly, the stair treads themselves left natural, like an architectural contemporRy stAtement, the natural timber tones will be rich and sophisticated and act as art inviting you to the home. These stairs would really pop and be commentedon at street level, also consider lights in each tread, perhaps the slatted wall side to highlight both this and the stirs for night practicality. What a stunning entrance. The natural character in rich timber tones will warm the grey, keep it contemporary and not introduce personalized colour, which can take away from street appeal. This on the other hand, appeals to everyone. And greenery, landscaping will only take this to the next level. Literally!

I desperately in need of advice as I cannot make a decission.... sorry, pics are in comments as I could not attach them here, new to this.... 1. I am unsure which colour to paint the front door, the wooden has an ugly stained brownish colour, happy to sand or to paint, but mental block about colour - grey/black or white? 2. Thinking about recladding the bricks with horizontal wooden slates as per last pic.Is that a good idea? Not suited? Friends say too expansive here in NZ but i am happy to pay if it will suit the house. 3.Shall we put a deck in front of the french door connecting the entrance, which I would then cover with wood as well to get rid of the concrete. Too much wood? And what about the planters, leave the bricks, cover as well, I prefer to cover them.Input much appriciate as my dear partner would leave it as is:) House specs: 1951 house, render, with the bit of fake brick in the front. The entrance face the front garden, it is visible from the street through trees.I love the good size garden, obviously the deck will take a bit away, hence I would not choose a big deck. My thought deck and then one step down to sit on as well, if that makes sense.Thanks for everybodies input - i am in the brainstorming phase. We are in the South Island New Zealand. Sorry, struggling with uploading pics. I will keep trying to get the photo of the whole house up.Screen just turns white when i try to upload
