Pine tree and its roots

[jana782001]

I have a pine tree in front of my house, three steps from the window.
I would like to remove the tree because it just too big and it blocks the light for us and our neighbour. I am aware that if I remove the tree there might be problem with my house. But if I just chopped the tree and leave the roots, would it not help? Gave it time to the earth to get used to it slowly? I would like to then put grass down and I have bush trees around too to help with the water levels. Please advice me.

The best advice would be to seek out an arboriculturist locally. Much depends on the type of soil you have, with clay being the main culprit at causing problems.
The solution you suggest would not assist. When the trunk of the tree is chopped, the roots stop taking up water from the surrounding soil. This can result in heave - a swelling of clay soils as they have far more water in them than they are used to. That in turn may impact the ground close to the foundations of your property and hence cause movement in the foundations. Whether you leave the roots in situ is immaterial.
