Creating A Peaceful Coastal Retreat Should be Enjoyable

You just bought a coastal home, and now you have to furnish it (or finish it out).

  • Are you worried about spending all your time on design details when you could be enjoying your home? 
  • Does the design process stress you out? 
  • Are you concerned about making choices you’ll regret later?

It can be overwhelming to know how to make your house the home you envision without burning the candle at both ends.

Professional Design services
to create the coastal home you desire


Hi, I’m Shannon Willey, Owner of Sea Green Designs. I have been helping homeowners in Southampton and beyond overcome design overwhelm for 20 years.

At Sea Green Designs, we understand how overwhelming the design process can be. Most of our clients already had full calendars before they decided to take on a design project, and they don’t want to spend all their time worrying about selecting paint and fixtures. Does that sound like you? We can help.

From start to finish, we can anticipate many surprises, help you avoid common pitfalls, and we can recommend vetted contractors or work alongside your contractor to get the job done right. You’ll be able to be included in all the decisions, without the hassle of worrying about the details. We’ll take care of making your vision a reality.

A beautiful space that feels like you
