Creating bespoke
residential,
commercial, and
hospitality spaces.

Based in Philadelphia and New York City, designing internationally.

We shape homes and gathering places around their architecture, their purpose, and the people who use them, bringing a distinct creative vision and the discipline to carry it through.

The studio

Founded by husband-and-wife team Autumn Oser and Andre Golsorkhi, Haldon grew out of a shared belief that the most compelling spaces have a distinct point of view — and a way of bringing people together.

Our work is inspired by the people we design for and the character of each place. With no predetermined aesthetic, we approach every project with curiosity, drawing on our clients’ lives, tastes, and ambitions to create spaces that feel personal, imaginative, and entirely their own.

Autumn leads design, while Andre leads the business and development side of the practice. Rooted in Pennsylvania’s historic Main Line, Haldon now works across residential, commercial, and hospitality projects nationally and internationally, creating places full of character that people feel connected to.

Our approach

Homes with a point
of view

Every project begins with you - how you live, what you love, and what you imagine for your home. We bring a fresh perspective to those conversations, finding unexpected possibilities in the character of a property and shaping a vision that feels distinctly yours.

Dining room

Rich,
soulful,
layered
and
timeless.

Old world and contemporary in balance, impossible to pin to an era. Expressive materials, custom details, and an artful mix of antique, vintage, and contemporary pieces create interiors with depth and individuality - collected over time, personal from the start.
