The front part of the house gets sunshine, so that is the kitchen, dining, living areas, where you need the light in Summer and winter. The back part of the house doesn't get a lot of sunlight. We have lots of trees in the backyard. We live in a semi rural area so there lots of trees EVERYWHERE. I like my trees so I don't mind. They provide great shade. The forest starts on the other side of the road, and covers the whole mountain. There are bedrooms out the back of the house, so it is good for the trees to keep them cool and shaded in the Summer. It was important for us that the kids ,as babies, weren't woken too early by blazing sun, despite the block out drapes. We are happy with the position of our house, and don't mind sharing the sun with the trees. Moved here to get away from the concrete jungle when we married.
