45 Architecture & Interiors is a planning, architecture, and interior design firm offering comprehensive design services for custom residential, commercial, public, and community-focused projects. Our work often begins with early visioning, site analysis, and project strategy, then moves through schematic design, design development, construction documents, permitting support, and construction administration.We also offer interior design as an integrated part of the architectural process or as a stand-alone service when appropriate.

Very involved. We see clients as collaborators and believe the best work comes from an honest exchange of ideas. Our role is to guide, translate, and refine—helping you articulate what matters most and turning that into a design that feels both unexpected and deeply right.The goal is not to impose a style. The goal is to uncover a solution that fits your life, your site, and your vision.

We are best suited for clients who value a collaborative, design-focused process and are looking to create spaces that are both highly functional and deeply connected to their context. Our work spans residential, civic, and hospitality projects of varying scales. We believe in people who believe in their project and we are excited to truly create something new with them.

Yes. While 45 Architecture & Interiors is rooted in Bozeman and deeply connected to the Montana landscape, we regularly work on projects beyond the state. Our experience spans residential, civic, and mixed-use work in markets throughout the Mountain West and beyond. What remains consistent is our approach: thoughtful design grounded in place, climate responsiveness, and disciplined project management. When working outside Montana, we collaborate closely with local consultants and builders to ensure code compliance, permitting alignment, and regional construction expertise. Our process — from schematic design through construction administration — remains structured and transparent regardless of location. Many of our out-of-state clients are drawn to the same qualities that define our Montana work: strong architectural identity, attention to craft, and a steady guide through complex decisions. If your project aligns with our expertise and values, geography does not limit the partnership.

Bring an architect on as early as possible—ideally before purchasing land or beginning design conversations. Early involvement allows us to evaluate site opportunities, align budget expectations, and guide the overall vision before costly decisions are made.

It helps to come with a general idea of your goals, budget, timeline, site information, and any reference images or examples you like. If you already have property details, existing drawings, or a program list, that is helpful as well. We use the first meeting to understand the project and determine the best path forward.

Every project is different. Timeline depends on the size and complexity of the project, decision-making pace, consultant coordination, permitting requirements, and construction goals. At the beginning of each project, we outline a proposed schedule so the team understands the major phases and milestones. Most projects take between 9 months and a year to design with a year to two years to build.

Our fees depend on the scope, complexity, and delivery method of the project. After an initial conversation, we can outline a fee approach that fits the work, whether it is a custom home, commercial space, or civic project. We aim to be clear about expectations early so you can plan with confidence.

We believe in a human-first approach to design and actively contribute to the community through initiatives like providing pro bono design work for individuals affected by wildfires. Our designs aim to leave a lasting and positive impact.

We bring together original design thinking, technical expertise, and a grounded understanding of what it takes to build in Montana and the surrounding region. Clients often come to us with a unique idea or challenge, and we help shape it into something clear, buildable, and meaningful.We see ourselves as trusted advisors—not just designers. That means helping clients think through site strategy, budget, relationships, development considerations, and long-term value.

Yes. In addition to new buildings, we also take on renovations, additions, and projects that reimagine existing spaces. We look at what should be preserved, what should change, and how to make the final design work better for the site and the people using it.
