I just think it needs more bright white trim around the windows and the fence painted also white. Going round to the back addition, I would paint the timber boards the color of the stucco, trim white and get some great deck furniture and lighting.

What climate zone are you in or where are you located? Can you take a photo that shows the entire front yard? I can't tell where you park or how guests walk to your front door. If you search Houzz for 'entrance gardens' you will see many examples of homes with wide paths leading from the street to the front door. Do you like to garden? You have a lovely house and would not want to hide any of the porch area so keep the plantings around the porch low. You can plant some taller plants at the base of each post but these should also stay low and not get higher than 3' to 4'. It looks like the garage may be in the back of the house with a fence along the driveway. You could have low growing roses along the fence and flower beds at the front of the house if you like to garden. Location and more pictures would help us to give suggestions for the garden.

I like @kelly's idea of picking a lovely fresh color of paint for the door. You can then bring it down onto the stair risers. Either a solid color to match the front door, or go wild and add some decorative elements to the risers with stencils. Or think of staining the door a great color and coordinate the stair railings and risers. I have an idea book put together for just such project that might spark some ideas for you. http://www.houzz.com/ideabooks/16700983/thumbs/Kathryn-Delany-s-Decorative-Stair-Risers

Like your house! I think the verticals in the window on the left are vertical blinds - get rid of these - they are very dating. Paint the horizontal safety bars to match your other window frames. I think the house just lacks privacy - and this then necessitates curtains and blinds at all the windows, giving the house a closed off look. I would get rid of all the very solid and 60s era conifer shrubs and replace with softer planting and one or two taller trees. Perhaps a fence or hedge to provide privacy so those windows could be opened up to the sun and garden. Or you could plant a row of spaced standard trees (fluffy heads on trimmed trunks) (eg robinia, or a weeping standard poplar or willow) you'd only need about 5 along the street frontage, creeper round that letterbox, a few pretty plants next the house. Then open the blinds and curtains. You could add a screened courtyard outside the glazed area on the left. Talk to your local garden shop for ideas. I cant tell whether the walls are brown brick or brown Summerhill stone (thats those rough concrete bricks, also very 60s). My house is Summerhill stone and has been painted cream - looks fine and certainly removes the 60s look. Hope this gives you some ideas - good luck with your new house.
