About

Blacksand Projects was born from the shared vision of two industry leaders — Michael Schwalbach, founder of Sandberg Estates, and Juan Manrique, founder of NEGRE Studio. Together, they bring a unique blend of expertise, creativity, and craftsmanship to the world of luxury property development in Mallorca.

With over 12 years of experience in the island’s high-end real estate market, Michael has built a reputation for integrity, precision, and a deep understanding of what discerning clients seek. Juan, with 15 years leading NEGRE Studio, brings a mastery of luxury architecture and design, renowned for creating timeless spaces that are as functional as they are emotionally engaging.

The name Blacksand reflects this partnership: a fusion of Sand, from Sandberg, and Black, the English translation of NEGRE. It represents two distinct strengths — real estate insight and architectural innovation — coming together to create something new, balanced, and extraordinary.

Based in Mallorca, Blacksand Projects specialises in the creation of bespoke homes in some of the island’s most sought-after locations, including Santa Catalina, Palma, and Calvià.

Our philosophy is rooted in exceptional quality, meticulous attention to detail, and timeless elegance. Each project reflects a dialogue between tradition and modernity — a celebration of Mallorca’s spirit, reimagined for contemporary living. More than buildings, we create homes with soul — spaces that embody warmth, personality, and purpose.

At Blacksand, we believe first impressions matter, but a lasting impact defines true success. Through thoughtful design, consistent visual storytelling, and a commitment to excellence, we don’t just build homes — we craft elevated living experiences that inspire, surprise, and endure.
