Similar idea as prefab homes.

A rule of thumb is that the distance between the house and a eucalyptus should be 2/3 the height of the tree. So if the tree is maybe 45 feet, you'd want the house to be a little over 29 feet away. As well as any new root growth that could affect your house, cutting into a root system compromises the stability of the tree. Also, even if the existing roots are deep, driving over the area with heavy construction machinery could compact the soil enough to affect the health of the tree. That's not to say that you shouldn't try, just be aware in case it becomes necessary to cut the tree down later. Good luck and enjoy your new home!

What color could we paint the exterior foundation color of this house? It’s currently painted 3 different shades of grey. Small deck is being completely redone so doesn't need to be taken into consideration. thank you
