For me it’s maximalism. Lovely in a quirky cafe or boutique hotel but at home it would give me a headache. I like a restful house and so yes quite a lot of it is grey! Not battleship grey or anthracite but bluey or greeny greys. Concrete floors. Depressing, cold, ecologically not great, look unfinished. Plants very high up. How do you water them? Walk in wardrobes even if it means the bedroom becomes tiny. I’d rather have a bigger bedroom with wardrobes in it, than dress and sleep in tiny spaces. Uber industrial. There’s a reason we usually hide cables, conduits, vent ducts...because they are ugly. Buying new furniture and accessories very often to have an “up to date“ look. I see all these instagram pictures with everything brass, mid century, wood, rattan, green (today’s trends) and I wonder what has happened to all their grey, painted, silver, shabby chic items from 5/10 years ago. And what will they do with today’s items when the look swings round again...

I think i'd find out from the local council about any wants and wishes they might have and any restrictions. I don't think that massively grand plans are warranted on this type of property. Yes, of course you want it to look nice, but just because some things are possible, doesn't make them a good idea every time, and everyone has a budget, Radically changing the exterior in this case needs to be kept in the realms of realistic for the style and situ of the property and end re-sale price plus type of purchase likely to buy. Going ultra modern and pie in the sky with ideas is a waste of money most probably. Grey windows do not in my opinion sit well with red brick for instance or a brown roof. You could render then whole facade in a colour of your choice or paint the bricks to darken down with iron oxide and make them sit better with Grey. The driveway needs an uplift and you'd have to address the finish and colour of the wall to the perimeter to match. A pitched roof to tie in would also, in my opinion look better.

It all comes down to budget as always. The bigger the budge the more you can do. I would be really mindful of the fact, that if you change the facade, it would be better if you could change the windows. The wood cladding I agree would look fabulous, you could have the bottom a lovely grey to tone in. However, neither will look good with bog standard white windows, as both look better with a dark grey, thinner Aluminium Frame or a Chunkier Sandy Beige Frame. When you add white windows, the effect is not quite so slick The pic above shows the white windows with the cladding and it would look a lot better with the darker, thinner frames. If you can't afford to change or colour bond the windows, then maybe go for all over colour, a dark grey would be good, and consider changing the Front door for impact. Alternatively, work towards doing the ultimate change. The vertical wood cladding, with a grey underneath and a door to match the wood. Thinner dark pewter aluminium framed windows etc. sorry about the mock up quality!

I think your house is really pretty and I love the terracotta tiles which will grow more beautiful as they age. The brown windows and door are the problems. The soft grey greens and taupes look lovely with red brick so painting the windows will be a great improvement. if you prefer white windows, it will still be an improvement and then you can have a bright, colourful door. I agree removing the big round shrub by the front door will open up the frontage, but leave the rest of the plants. Here’s some window colour ideas.
