Healthy Homes.
Built to Last.

Our design-build model brings together top architects, designers, and craftsmen for exceptional results and a seamless experience.

Your home should work as hard as you do.

The best homes make life better for the people inside them. Clean air, natural light. Spaces that work with the way you actually live. Construction that happens on schedule, on budget, with you knowing exactly what's happening every step of the way. That's what we do.

Why Coastline?

We are a small, high-performance team focused on one thing - creating exceptional spaces.

Here's why clients trust us with their projects:
Flexibility & Freedom
Our flexible approach matches you with the perfect team and service level for your project. Unlike builders limited to in-house designers, we collaborate with San Diego's top architects and designers—giving you access to the best talent without compromise.

No locked-in contracts. We separate design and construction agreements so you maintain control throughout your project. If you're not thrilled with our proposal after design, there's no obligation. We only want to build with clients who genuinely want to work with us.
Sustainable Building Practices
We carefully select materials and building methods that create healthier, more comfortable homes. Our energy-efficient, high-performance designs combine premium materials with meticulous craftsmanship—protecting both your family's well-being and your investment value for decades to come.
