Likhitha Varikuti
M.Arch, LEED Green Associate
Likhitha is an architectural designer and recent graduate of the University of Waterloo. She is dedicated to tackling global challenges through adaptive reuse, climate-responsive architecture, and carbon reduction strategies.

Her master’s thesis, Descent to Water: Revitalization of Ashapura Stepwell, reimagines ancient Indian stepwells as catalysts for groundwater recharge and self-sustaining neighbourhoods—linking cultural memory with urgent environmental needs. This project reflects her broader commitment to using architecture as a tool to address climate change. At Ha/f, Likhitha contributes to life cycle assessments, climate resiliency strategies, and material reuse studies, advancing projects that prioritize carbon reduction and circularity. Driven by a desire to create meaningful impact, her work bridges technical rigor with environmental stewardship to advance sustainable futures.
