Our style is relaxed coastal with soul — where beauty meets livability. We combine clean lines, organic textures, and soft coastal tones to create homes that feel effortless, welcoming, and lived-in in the best way.

St. Augustine Design is led by Ashleigh Kosin, an ASID-affiliated interior designer with over 16 years of experience designing and furnishing homes across the country.

With a background in running a high-end furniture and design studio, Ashleigh brings a deep understanding of floor plans, layout, scale, color, and quality — not just styling. From the first space plan to the final installation, every detail is thoughtfully considered.

Our experience makes the process feel easy, organized, and stress-free, resulting in homes that are relaxed, timeless, and beautifully livable.

No. While we’re based in St. Augustine, we work with clients across Florida, Michigan, and nationwide through virtual design and our white-glove furniture delivery service. For larger full-service projects, we’re also happy to travel to you, allowing us to support clients wherever their home — or second home — may be.

This flexibility lets us serve everything from local beach houses to lake homes and vacation properties across the country, all with the same thoughtful, hands-on design experience.

We do! Our virtual design services are perfect for clients outside our local area or those who want expert guidance while handling some of the execution themselves. You’ll receive layouts, product links, and a clear plan to bring your space together beautifully.

Absolutely — and it’s one of our specialties. We design vacation rentals and second homes to be both beautiful and hardworking. Using performance fabrics, thoughtful layouts, and timeless coastal style, we create spaces that photograph beautifully and stand up to real life.

We also handle the styling and finishing touches — art, lighting, pillows, and accent pieces — to create a warm, layered sanctuary that feels special the moment guests walk in. The goal is to design a true escape that guests remember, love, and can’t wait to return to.

Yes. We source from high-end, designer-only lines and offer custom furniture, rugs, lighting, and accessories. We also provide nationwide white-glove delivery, so your pieces arrive handled with care and placed beautifully in your home.

White-glove delivery means your furniture is delivered, placed, assembled, and all packaging is removed — no curbside drop-offs and no hassle. We offer this service nationwide, which makes our virtual design services an easy, seamless option no matter where you live.

You get the same curated, designer experience and professional installation — even from across the country — so your home comes together effortlessly and beautifully.

Start by booking a design consultation. We’ll talk through your space, your goals, and how you want your home to feel — then create a clear, thoughtful plan to bring it all together. Whether you’re refreshing a room or designing an entire home, we’ll guide you every step of the way so the process feels simple, inspired, and stress-free.
