We design architecture and interiors as one.

Great architecture and interior design should feel connected.

From the proportions of a space to the materials, lighting, sightlines and smallest details, everything is designed to work together.

Trivera Estate. A study in light, landscape and quiet architecture, where the home becomes part of its surroundings.

08/17/2026

We always think about how a home will feel years from now.

The proportions. The natural light. The way materials age. The view from one room into another. And the moments you experience every day without necessarily realizing they were designed.

This home was created for a family who wanted a place that could be lived in, loved and passed down for generations.

That idea shaped everything.

Honored to be featured by the International Interior Design Association (IIDA) discussing the importance of “third spaces” and why outdoor courtyards continue to inspire my work. I believe the most memorable spaces aren’t always inside four walls. They’re the places between architecture and nature where people gather, connect, and simply enjoy being together. Thank you to IIDA for including Welch Design Studio in this thoughtful conversation about the future of design.

A warm modern kitchen we designed in Newport Beach.
We love the mix of wood, black stone, soft lighting, and the long fireplace wall.

Trivera Estate came together with some pretty incredible clients who had a lot of creative ideas and trusted the process.
This one felt special from the start.
