ABOUT US

We are a deeply collaborative interior architecture and design studio focused on creating refined innovation for both residential and commercial projects.

Led by Karina Marshall — with past lives lived in design innovation and foresight strategy — the studio cultivates a futurist approach to interiors. Particularly as Eichler & MCM specialists, we aim to bridge the critical gap between maintaining the integrity of classic modernism while designing for today and tomorrow.

Armed with an extensive and ever-expanding materials library, roster of expert drafters, engineers, contractors, custom fabricators, and global manufacturers, we distill our design experience into a bespoke, personalized practice. 

Our work is highly personal for us — each project is a reflection of a deeply trusting relationships with our clients that live far beyond project completion.

This phase establishes the core layout and design approach before moving into detailed development.

    During this phase, we coordinate the execution of the design on site. This includes reviewing cabinetry development, overseeing material and fixture installation, and resolving design-related issues as they arise. We hold regular weekly check-ins with the project team to ensure the design is implemented accurately and stays on track.
