Raise the Roof

Yolanda Chen

The last two months have been a busier than ever as we moved into Phase 2 of Onsight's construction. Along with Carico Construction, we tore off the old roof and got ourselves a temporary, unobstructed, open view of the bright blue skies (yes, the rainy days were rough). The steel guys came in with truckloads of massive beams and columns and we started going up, up, and 57 feet! The view from way up there is amazing. Walltopia is showing up with our climbing walls in a few short weeks and we can hardly contain our excitement. We are working hard on putting on all the finishing touches to prepare for their arrival and the erection of over 12,000 square feet of climbing surface! You will all be able to get your hands (and feet) on it soon. Stay tuned for the announcement of our pre-opening membership sale!
