Billed as the best thing to have happened to San Francisco since the chicken and waffle box, indoor trampoline park House of Air, which will go into the old Presidio airplane hanger space, is set to open in August. As Curbed notes, it will boast "a glass hangar door, conference rooms, and 'trampoline training grounds' with a combination of trampolines and trampoline walls 'allowing for maximum air time.'"

Trampoline walls? Quiver.

Be sure to check out more 3-D renderings of the park -- one that promises to give "flight to the flightless" -- at Curbed.
