What a fantastic architecture. When you do the brick, if you stain it with masonry /concrete stain you won't have the same issues of maintenance as with paint. They will spray it evenly - through you will have to select a deeper color - either taupe (brown-gray) or a straight charcoal. Love your windows and the classic angled railing. I think a dark gray on the siding will make the orange brick jump even more. What bothers me is the white (railing, fascia, eaves) juxtaposed with the earth toned stuff. So I would recommend camel tones - for the siding - something like http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6108-latte/ and the hopsack next darker tone for the garage door. Use the lighter tan for trim that is now white - http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6107-nomadic-desert/ Use the darkest tone if you are painting concrete steps. If you think you will stain your brick charcoal, then the white eaves and trim are probably right, and you may not want to paint it tan now and then go back. If your brick were charcoal, then I would block out the rest in grays and blue grays - leave the white eaves, but take the railing and posts charcoal too. A blue gray door - like sw smoky blue.

With any post war house built in the 50's the connection from in to out is non existent. Depending on where living rooms are located i would take some of the fantastic windows out and replace them with French doors, or bi folding doors and connect the house to the site. The colour scheme from Karen is perfect to lift the kerb appeal and give it a modern twist. With land costing more than houses these days and the fact that you seem to have quite a big block, after looking at paint colours, opening up the living dining kitchen areas to the outside with a roofed area. Even combining a flat roofed carport which will widen the house to the street making it seem a bigger house, can carry the new look with say an enclosed section for garden equipment, to the opposite side to the house, and if you are lucky enough to have that near the living area it can be used as both car cover and outdoor living. I always think a good landscape architect is worth their weight in gold, to give you a landscape plan, to suit the soil type, your skills level and your preference in planting. Divide up the exterior space to provide outdoor rooms under a tree, paths that lead to some special spot for kids, maybe even a veggie patch with a chock run, and make sure that you use the entire yard, front and back by enclosing part of the front yard in fencing which suits the style of the house, while providing some planting to the street. If allowed a gate structure to blend in with the house, a dedicated pathway with planting each side to the front door, fantastic fencing and consider natural materials like a hand laid stone fence with timber or powder-coated aluminium inserts, to give this house an entry, not sure where the front door is now, so that is not a good look. Gardens always enhance a house, they are never a wasted effort, and if you are not gardeners, make sure the landscape architect knows that and he will be able to select low maintenance plants. All the paint in the world will not give the desired effort that the garden will do to that paint work.
