Construction is well underway on the highly anticipated SLS Madrid Infantas Residences, a landmark redevelopment in the prestigious Barrio de Justicia. Working closely with Persepolis Investments and the design team, leading firm Sorigué will serve as the construction manager in the transformation of the 1920s Neo-Baroque building into an exclusive collection of 33 luxury residences.
The extensive project will ensure the integration of classic Spanish architectural elements with thoughtful and contextual modern innovations. The development remains on schedule, with completion anticipated in 2026.
Since its launch, SLS Madrid Infantas Residences has garnered significant interest from both local and international buyers. With substantial sales velocity already underway, the project has established itself as one of Madrid’s most sought-after residential offerings.
The project is already generating strong momentum as an exclusive social hub in a prime Madrid location, offering a unique blend of heritage, modern luxury, and the vibrant energy that defines the SLS brand.
As the first SLS-branded residences in Europe, this project introduces a bold new standard in Madrid’s high-end real estate market. The design, led by Natureback (architecture) and Studio Carter (interiors), merges grand period features—such as elegant moldings, brass finishes, and soaring ceilings—with cutting-edge amenities, including underfloor heating and cooling, Bulthaup kitchens with Gaggenau appliances, and marble-detailed bathrooms. Penthouses feature private terraces with panoramic views of Madrid, offering residents an unparalleled living experience.
Situated in Barrio de Justicia, one of Madrid’s most sought-after neighbourhoods, the project provides a lifestyle designed to balance exclusivity and accessibility. Justicia is a dynamic, cosmopolitan district known for its Michelin-starred restaurants, luxury boutiques, and cultural landmarks, including the Museo del Prado and the Teatro Calderon. Residents will enjoy a short walk to the greenery of El Retiro Park and quick access to Madrid’s shopping avenues, including Gran Via and Serrano.
At the heart of the project is the SLS Social House, a curated collection of private amenities designed to elevate daily life. This exclusive residents’ club features a library, wine cellar, high-end games area, a snug, private dining space, a podcast/media studio, and a screening room, fostering a sense of community within the development.
Wellness and relaxation are key focuses, with an indoor lap pool accompanied by a fireplace, a boutique fitness studio, and on-demand treatment rooms. The rooftop has a pool surrounded by lush gardens, a meditation zone, a yoga deck, an outdoor kitchen, and a sunset terrace with views of Madrid.
