about
more than design
Grummer Architecture is a design-focused practice based in Portland, Oregon. We create modern, enduring homes through a process that is clear, collaborative, and deeply personal.
People come to us because design alone isn’t enough. They want clarity, guidance, and a partner who sees the bigger picture. Someone who can simplify complexity, align the vision and the budget, and guide them to a lasting result.
how we work
Designing a home is personal. It’s about creating a space that reflects how you live and what you value, not just how it looks on paper.
Whether you're starting fresh or reworking an existing space, we design homes that reflect how you live and where you're headed next.
We take the time to listen, collaborate, and translate your goals into something lasting and meaningful. This isn’t a handoff. It’s a partnership.
clarity and guidance
We set expectations early, simplify decisions, and help you navigate the process with confidence.
Personal connection
Every project begins with listening. Your home should reflect your life, your needs, and your values.
thoughtful execution
We prioritize lasting materials, smart details, and a design process that feels structured and human.
why we do this
In architecture, it’s not uncommon for clients to feel left in the dark—unsure where their time or money is going, or what comes next. Beautiful designs may result, but the process behind them can feel scattered or unclear.
We built this practice to do things differently. At Grummer Architecture, communication is the foundation. We define expectations early, lead with transparency, and treat the experience as carefully as the outcome. Because great design should feel good from the very beginning.
