Our People, Our Story.
Interwest Construction was founded on a simple conviction: the people leading a project should know how to build it. That principle shapes every team we assemble, every plan we execute, and every community we deliver.
Building Big Ideas. Delivering Real Impact.
Taylor Brown and Donovan Sliman didn't start Interwest Construction from a boardroom. They started it from the field, bringing decades of hands-on construction experience into a firm designed around one idea: leadership that stays close to the work. Their partnership created a culture where accountability isn't a policy. It's a practice.
Who We Are
We're a focused firm, by design, not by default. Staying lean means our principals remain embedded in every project, not delegating from a distance. Our team leads with construction knowledge, not just management process. The result is faster decisions, fewer surprises, and a level of quality control that larger firms struggle to match.
We hire people who take their work personally. From project executives to field teams, every member of Interwest operates with the understanding that their name is on the work and that the work has to last.
How We Execute
We partner with developers and owners to deliver multifamily and single-family communities from concept through closeout. Our process is built around clear coordination, direct communication, and a structured rhythm of oversight that keeps projects predictable, even when conditions aren't.
We don't chase scale for its own sake. Every project gets the attention, planning, and resources it demands. That restraint is what allows us to deliver consistently, on time, on budget, and at a standard that speaks for itself.
Why We Succeed
For us, quality isn't a final inspection, it's a discipline that starts before the first shovel hits dirt. Early engagement, proactive oversight, and continuous verification at every phase allow us to control risk, protect timelines, and deliver work that performs long after the last walkthrough.
Our leaders don't oversee from the sidelines. They're in the details, reviewing plans, walking sites, and making the calls that keep projects on track. When leadership is this close to the work, problems get solved before they compound.
