Thinking a bit differently maybe landscaping would give you a better result? The colour scheme is quite complementary and doesn't look like it needs changing?

How about re-turfing / reviving the grass, potted topiaries at either side of the portico, a few feature conifers or other tall skinny plants / trees planted against the pillars and few plants under the window?

The brickwork just needs a good clean with a high pressure hose and brush.

Ah right, I personally quite like the white on the doors and slats but would recommend matching the colour with the existing window trim and garage door. Will the pillars be eventually rendered? If so, stick with a similar colour as the bricks. Less is more :)

Do you like colour? If so, a nice deep red or burgandy would look great for the front door, or otherwise to bring the woodland grey down and paint the doors in woodland grey. Then I would keep the render colour the same as the roller door. Just personally think with the doors set back in, and have quite a plainer scheme, you maybe need something a bit deeper on your doors to give an instant impression.

Hi yes I agree u need color, what about blue , the color off the sky in the photo that would be nice and I do like the suggestion of red as well. The timber above the window maybe the same as roof or a bit lighter or something to make it look like stained wood ,and 2 nice pots in front of your pillars in the same coloras your front door

With the timber above the window, do it the same as the roof as you suggested or maybe 75% strength, and then with the front door you could do blue(may look a little cheap or commercial colouring? :) ) for a red I would look at doing the colour in Dulux Red Box. If you do like the colour blue and want to do that, could look at Dulux True Blue or Blue Regent.

Love those ideas, Louise!
