Our Story

LeyLines Developments
Founded by long-term business partners and friends, LeyLines was built on a shared vision to capture the growing potential of luxury real estate in Southeast Asia..
While spending months in Bali, Indonesia, we've identified the Bukit area as the perfect location for our first projects. It's the place in which we believe our decades of construction and real estate experience can add the most value to guests and investors alike.
Our journey began with acquiring prime land and developing ADAYA, a luxury villa complex near Dreamland Beach. The project garnered significant interest from investors who believed in ADAYA's unique positioning and LeyLines' commitment to excellence. These 15 investors formed the foundation of our fast-growing the LeyLines community.
Inspired by an ancient idea
Inspired by the concept of leylines, discovered in the early 20th century, we embrace and expand upon these straight alignments that connect timeless natural beauty with historical structures and prominent landmarks. At LeyLines, we blend modern luxury with the enchanting allure of nature and history, creating properties that are both beautiful and profitable.
Our Mission: Transforming Luxury Living
LeyLines delivers an unparalleled living experience that transcends the ordinary, where luxury aligns with ancient energy to create a sanctuary of serenity, beauty, and inspiration.
