We specialize in tenant improvements and can assist with space planning, suggesting alternate materials for cost savings, processing of plans through the city and coordination with Austin Energy.

US Cryotherapy Austin: We designed this space and took the plans through the city and Austin Energy. This was a tenant improvement build in an old building near downtown Austin and required upgrading the entire electrical system to 3 phase power which required coordination through Austin Energy. 

It was about a 4 week build to turnover to the Franchise to add their proprietary equipment (which took 2 additional weeks) and the new power system was done in that time. This was accomplished on time and on budget.
