Interior Architecture

Interior Architecture designs or modifies building space for the benefit of user experience and function.

This includes architectural stairs, elevators, mezzanines, roof terraces, public corridors, fire separations, and space planning.

We are experienced in all three major areas of interior architecture:

Architectural Stairs

Gunmetal steel stair with continuous bent plate treads and risers with expanded metal lath guards and hardwood handrail.
