Usually the bedroom are adjancent to each other, not with a kitchen in the corner. Why do you need two bathrooms in the front by the stairs? Attached is a crude layout of the rooms. Hope it gives you more ideas. You can also search the net for basic fllor plans to get ideas.

Right now there does not seem to be any symmetry on the path to your door. I would either eliminate the small trees that are there now, and replace them with bushes or shrubs that are equal in height and width, or cut these back and shape them dramatically, so that you have a clear vision to the door. Second, if you could change out the door, eliminating the side window, that's another idea. Sometimes just replacing your front door with one that is bold in color or style is enough to breathe some life into the front of the house. You could also either replace the concrete with pavers or paint the concrete with stain of a color that blends well with with nature.. like a lighter gray or a brown.

There are a number of factors that will dictate the design of your house. The first step is to visit the local building department to find out the restrictions for your lot. Do you need to set back the house from the property lines? Is there a maximum site coverage that the jurisdiction allows? For example, in San Clemente, California you can only cover 50% of your lot with your house. Do you need to include parking on your site? Most cities in the USA require 2 parking spaces on the site. The shape of the lot and the access to the lot as well as any potential views, and even the location of the sun and the prevailing winds will impact your design. Find out the information that I listed above and post it with a dimensioned site plan and you may get some great design suggestions.
