My friend John Murphy does static trapeze work with his troupe "The Cabriri", and purchased a house with an immense basement room.

The arch had to both support the house above, so we could remove all the existing support posts, and be used for acrobatic training.

Like a massive adult jungle-gym.

The hardest part was actually getting the pieces into the space.

The second arch was not load-bearing, and was simply for more hand holds.
