Weird fuzz/shading error on a render of a house model. Help?

Question

enter image description here

As you can see in the render above, there is some weird fuzz on the side of the house, as well as some sort of spiky shade in the triangular area. I would like to know what causes that fuzz.

More importantly, I want to fix the triangular area shading error. It really ruins the look of the house.

Here is another view of it.

How can I fix the fuzz shading and the shading error in the triangular part of the roof? What is causing this? I already tried removing doubles and recalculating normals. The lighting is a combination of Environment Lighting of 0.760 and an Area Lamp shining directly on the front of the house.

That is Z fighting, and we have a plethora of questions on that on this site. Somewhere you have duplicate faces which is causing that problem. — David, Jul 09 '14 at 22:15

The problem on the triangle of your house is that there are intersecting meshes. To fix the issue, go into edit mode and hit W>Remove Doubles. also make sure that you don't have an duplicate objects.

To fix the noise, change this setting: enter image description here

The higher you set it, the less noise you will get, and the longer your render-times will become.
