Alberto Díez is the Founder and Design Director of diez.studio®, a multidisciplinary interior design firm based between Marbella and Palencia, recognised for its refined contemporary aesthetic and commitment to craftsmanship. With more than a decade of experience leading projects across Spain and abroad, Alberto has become one of the new voices shaping modern Mediterranean luxury.

A graduate of the Escuela Superior de Diseño de Madrid, Alberto began his career with the renowned design brand YOO in London, working on high-end residential and hospitality developments around the world. He later joined Pedro Peña Interior Design in Marbella as Senior Interior Designer, where he directed the creative concept of some of the region’s most prestigious private villas.

In 2015, Alberto founded diez.studio®, focusing on bespoke design that unites architecture, material, and light. His work blends clean lines with warmth and texture, creating spaces that are elegant, timeless, and deeply personal.

Alberto is also the lead interior designer for JUST Real Estate, overseeing the design of their own projects and collaborating on client villas and apartments undergoing renovation for resale and investment. His ability to harmonise design vision with market awareness ensures each project not only elevates its aesthetic appeal but also its long-term value.

Today, Alberto and JUST continue to shape Marbella’s design landscape — from signature villas in La Zagaleta and Puente Romano to exclusive developments and private commissions across Europe.
