Two months since my last post! Well, to conclude 3 Highland Phase I, we did some exterior work, which involved building this staircase. We were seeking a safe way to get to the roof that wasnt a rickety ladder. Ama and I build this alternating tread staircase that's shape was calculated based on ama's stair stride. Now we are figuring out a way to incorporate a railing. Updates and better pictures will follow!
