With the beautiful brown brickwork you need paint colors in more earthy tones. Cool greys and blues may clash. If you are in a hot coastal climate and want to keep the white make sure it is a warm white. A good field color could be the tan in the walk way brick. Mossy greens and dull golds could also work. Test color schemes with good old Crayola sketches to see if you like dark trim and a light field color or vice versa. Consider a bright pop of color for the door if the rest is very neutral creams and tans. Add lattice and screen to the sides of the foundation to keep critters out. Add shrubs and flowers. You need a tree or two. The porch begs for a swing or rocker.

We have a similar problem in that we really don't like our brickwork in our 1980 built home and have the dark brown window frames. Some people just can't understand why we dislike the bricks and I thought they may grow on me. After 4 years I still can't stand them and can't wait until we can afford to render. If we had a small area like yours I would have got it done long ago. Ours is huge. Don't be tempted to bag the walls. I've seen some shockers, usually people trying to do a cheap 'flip'. As for the windows, my uncle who is a painter & decorator said that as long as the frames are cleaned well they are OK to paint conventionally. The channels will be tricky, but ours need new felts etc. anyway.

With the roof tile colour I suggested off white, but NEVER WHITE as you'd need sunglasses to enter (talk to a roof painting company). It's also a way to minimize heat by reflection, therefore lowering cooling cost and making life more comfortable, plus very aesthetically appealing. Though the down side is more regular semi pressure cleaning. I do like mid to light grey for outside timber decking or tiles under a roof line with this colour combination. For anything else as far as outside in direct sunshine, stay light but in the same hues, it can be too hot to walk on barefooted if remotely mid to dark in colour.

Very light grey on all walls would be nice or white. Lighter colours like white tend to make spaces bigger and in ur case this needs to be done. The artwork on the weight bearing wall (in kitchen) needs to go as this draws ur eye to the wall . The railings on the stairs need to be painted (either colour of the walls or white)as this will help blend into the background and make the space look bigger.
