We created a different kind of development company.

Too often, home and community development can lose sight of the people and experiences that create a sense of place and attachment. We are a group of designers, builders, travelers, and community members who believe that meaningful spaces are a reflection of relationships.

We're inspired by the lifelong value of putting down roots.

We created Blue Flag Development because of the places we love and a sincere desire to help clients reconnect while they “get away.” Reconnecting with familiar faces and places, best kept secrets, and sacred shorelines are what turn homes into beacons - and keep us coming  back year after year.

We don't design spaces, we deliver a way of living.
