After digging out around the foundation, layers of landscaping fabric went down, along with at least 2' of gravel for adequate drainage.  The final gravel level was 6" lower than the concrete edge of the window opening.

We had access to a small loader which made the gravel step easier.

Then the railroad ties were cut to length.

THIS WAS THE WORST PART.

Using a chain saw, cutting the timbers varied so much from timber to timber.

The oil they are manufactured with to fireproof for railroad use made some harder than oak to cut.

My husband spent half the time sharpening the chain saw blades, sometimes only 1 cut between sharpenings.

To anchor the timbers, Rhett drilled holes vertically every 2 timbers with an 18" auger drill bit using a hammer drill.  

Then pounded rebar through the ties into the ground.  

Each 2 timbers made a "step" and the next 2 timbers were about 4-6" away, so the windo well sides were stairs for escape purposes.

Once the window well was complete, we wrapped it as best we could in tar paper, (to prevent water/mud from coming through the cracks) then pushed the dirt back up to support it.

The top rows were bolted down with washers to lower levels for a more pleasing look, and to avoid rebar poking out of holes on the top layer.

I think the final look is unique and fits the vibe of other timber and rustic elements in our home.

Once the ground on top is landscaped, floor cover plants will cascade down in to further enhance the view from the basement bedrooms.
