In order to suggest specific plants, I need to know what part of the country you live in. There are no shade trees it seems. I would take down the two shrubs at the front of the walk, including the purple one. Sorry. You can get the purple back elsewhere. They are overbearing and there's no symmetry. At the right corner of your home, not too close where the roots will damage the foundation or branches at maturity will touch the house, place a medium sized ornamental tree. At front, left corner, behind the mailbox ( you need a bigger, more updated one), maybe 5 feet to the right, place another tree. Pull out all the plants that are along the house and replace with evergreens, box woods? Just depends where you live. I would also pull out the white ground cover near the wall, just on the right, in order to achieve symmetry. I would paint the cream stucco a shade of gray darker than your roof and keep the trim white. Also, a new handrail would help freshen up the entry.

I wish I could post links to pics of others' houses that are already on HOUZZ. Does anyone know how? I've been inspired by a project called "San Francisco Mid-Century Mix" on here.

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.

I read an interesting comment somewhere, where a lady invited a group of her friends over to lovingly point out all the problems they saw (through fresh eyes) with her home on preparation for sale. She said she was surprised at marks and damage that she had lived with for so long she no longer noticed them. We "owner built" a home previously, and when we came to sell 7 years later, we painted the garage and did those jobs that we had put off, and it became sad to finally see her at her best, at the end, when we could have been living in a completely finished home all that time. I read about a lady who decluttered her home, had it professionally cleaned (build clean, or bond clean) and had a professional styler do her home and she realised just how nice it could be and decided not to sell. :) ta
