I don't think you can go wrong with a large timber door. The colour should contrast with the granite nicely and will even help soften all the colder surfaces. Have you seen any doors you like? https://www.houzz.com.au/products/front-doors-prbr0-br~t_10816

Most door companies stock what you are looking for.

I personally love the look of a Tudor style home but if you are looking for a more modernized american look I would suggest removing the trims and painting the entire house white. If your budget allows for re-cladding the roof or painting the existing cladding (maybe in a black or charcoal) that would help to modernize it as well. it would also give a dramatic contrast with the white and then add some navy or black shutters as well.

This may sound blunt , but it is so , so easy -- hide everything in your picture ! Look at the neighbours , a nice door and surrounds , in pleasant colours , with nice timber and bricks . Yours is square and open , with vertical wallboards ( maybe even synthetic or cement based ? ) , battening , a billy basic door and light , a window that is totally different again and even has a different coloured surround to the door ! So yes , change the door , do that whole wall or all 3 in a different finish . Do something about the cracked concrete path -- how about tile with terracota tiles , or white ones with a light blue pattern , right up to the door ? And the pipes -- do a canopy , or a facade in natural timber , or a sloping roof in the same material as your main roof -- hide them . Easier than moving them , and the associated risks implied there . I'm here in New Zealand , and I reckon you could do something including labour , and a door and side panels similar to your neighbours , for around $5000 , or $10,000 would be a real step up above your neighbours look haha . I assume your costs would be in that general range .
