A building envelope should be responsive and sympathetic to its environment – both inside and out.

With experience from critical international infrastructure projects, Mantis brings an evidence-based approach to building envelope design. 

Our data driven analysis of stability, material science, and weatherproofing systems delivers building envelopes that stand the test of time.
