Homes designed for real life, built to last in Seattle and on the Eastside.
Thoughtfully located, well-built infill homes that adapt as life changes and hold value over time.
Olsen Anderson's Story
Buying a home in Seattle and on the Eastside has become a high-stakes decision. Inventory is limited, many older homes are expensive and require significant time and money to maintain, and new construction at an attainable price is increasingly rare. At the same time, buyers worry that if they wait, prices will continue to rise and homeownership will move further out of reach.
That pressure makes it easy to rush, or to settle for a home that works for today but becomes a source of regret later.
Olsen Anderson started from a simple belief: if people are going to make one of the biggest financial and personal decisions of their lives, they deserve homes that are thoughtfully located, well built, and designed to hold up over time. Not homes optimized for listing photos or short-term trends, but homes that continue to work as life changes.
We focus on building modern infill homes in established Seattle neighborhoods, places where location, scarcity, and long-term demand matter. Our homes are designed around real life, with flexible floor plans that can adapt to growing families, aging parents, and work-from-home needs. We plan for longevity, incorporating features like all-electric systems, EV charging, and materials selected to perform in the Pacific Northwest, so ownership feels manageable, not burdensome.
Our approach is deliberate. We plan carefully, make decisions up front, and build with discipline so our homes age well and protect long-term value. And we stand behind what we build. Clear communication, a professional handoff, and accountability after closing aren’t extras, they’re part of the job.
At the end of the day, our work is about elevating how people live, by creating homes that support change, reduce risk in a constrained market, and give buyers a confident foundation to grow into over time.

The Olsen Anderson Difference
A vertically integrated approach, design-forward mindset, and partnership-driven philosophy, all working together.
Vertically Integrated by Design
We manage the entire development-to-delivery lifecycle. That control means tighter timelines, fewer surprises, and consistently better outcomes.
Built on Long-Term Partnerships
We operate as one aligned team with landowners, investors, designers, and builders. Transparency and follow-through are how work actually gets done.
Design That Holds Up Over Time
Our homes are designed around how people live every day, prioritizing livability, durability, and neighborhood fit, not trends.
A Proven Process for Predictable Outcomes
Every step — from feasibility to keys-in-hand — is aligned, accountable, and designed for clarity.
Our Promise
We own every step — so you can trust the outcome.
Our vertically integrated model isn’t just operational — it’s philosophical.
We never pass the buck. We don’t play games. And we’re here long after the project is complete.
We build for the long haul:
for the homeowners who live in our spaces,
for the partners who trust us,
and for the neighborhoods that deserve thoughtful growth.
When we say we’ll deliver, we do.
That’s our promise.
