About


Fresh Architectural Design

from the Mountains to the Deserts

Plum Architecture was founded in 2014 by Cole Robertson, who was born and raised in eastern Montana.

Inspiration of our work comes via the aesthetics of steel, millwork, glass, and simple structures that inform iconic western design. Fascinated by the endless possibilities in how these materials could dovetail and root within the landscapes of the West led him to Montana State University, where he earned a master's in architecture. 

Philosophy

Integrating wood and steel, structure and space, lines and curves, human elements and the natural world — an exploration of balance and interplay forms the foundation of our work at Plum. We provide clients with clean perspectives and understated elegance, melding form with function for built environments that serve practicality in their structure while inspiring wonder in their form. Our designs are inspired by — and speak to — the architecture of the past, the innovation of the present, and the living landscapes where everything is rooted.

Process

When you work with the team at Plum Architecture, expect to become part of the creative process. Roll up your sleeves, sharpen your pencil, and be ready to put all your wildest ideas on the table. We are proud to have created a truly collaborative design environment where clients and builders see their vision expressed in every wall, and every joint, of the finished build. Our greatest reward is achieving livability, luxury, and your enduring satisfaction — we design for life.

we specialize in residential, small commercial and renovations.

Residential: Our residential building plans are holistic, comprehensive, and driven by your big ideas. We use an iterative approach to residential design, providing clients with detailed concepts during the early stages of development. This nitty-gritty mindset allows you to see textures, shadows, and structural design elements months before you break ground. We take your vision, add our design expertise, and support your dream home from initial concept sketches to finish carpentry.

Commercial Buildings and Tenant Improvements: Commercial spaces can greatly impact creativity, productivity, and your company's bottom line. This mindset is front and center during our commercial design process, allowing our team to create fresh concepts that inspire and motivate employees, clients, and prospects. A partner for the duration of your build, our commercial design services begin with an initial consultation and continue through your grand opening.
