Seattle design-build, done right
From single-room remodels to full custom builds, Castello Design Build brings craftsmanship, clear communication, and real follow-through to every project.
What we do
-
Kitchens, baths, and whole-home renovations that transform how you live — without the stress that usually comes with them.
-
Seamless additions that expand your home's footprint without compromising its character or your budget.
-
Custom homes built from the foundation up, fully managed from design through final walkthrough.
How we work
-
We start with your goals, your budget, and your home's constraints, and build a plan around all three. Already working with a designer or architect? No problem, we can join your team as the builder.
-
Permitting, engineering, costing, and scheduling happen before a single wall comes down, so there are no surprises once we start.
-
One team, one point of contact, from the first day on site to the final walkthrough.
