The project of developing and exploring Interior Design came about in 2009, from a strong desire on the part of D.er. Mariana Esteves Serra to develop, deepen and create her theory and vision of the Interior Design. At Spaceroom the projects created and developed are of the highest quality, keeping the focus on the challenge of differentiation through exclusiveness and commitment extended to each project, translated into the needs and wishes of each client. Apart from the pieces designed and conceived by the studio, Spaceroom frequently falls back on classic and contemporary furniture from the great authors, both national and international, making sure each space is unique and unrepeatable. Each project that carries the Spaceroom signature is made up of details." Have nothing in your house that you do not know to be useful or believe to be beautiful. " William Morris.The Degree in Interior Design by ESAD, Superior School of Decorative Arts of the Ricar Espírito Santo Silva Foundation, gave D.er. Mariana Esteves Serra the vision to create a reference atelier where inspiration and creation are full of passion for the Art of Interior Design and Art in general. Her specialization in jewellery adds a touch of charm and glamour to projects signed by Spaceroom. The creative sensitivity allows her to anticipate trends, maintaining a personal touch on each project. Through the use of several custom materials, the designer integrates references, spaces and color concepts, making the difference, giving priority to the personality and needs of each client.

The Design Business Index (DBI) is a merit-based rating system and professional directory founded to address one of the design industry’s biggest challenges: the difficulty of reliably assessing a designer’s true capabilities before a project begins. Through its partnership with the internationally recognized A’ Design Award, DBI combines a rigorous blind review process with transparent evaluation criteria to transform subjective design quality into objective credentials. By featuring only those who have demonstrated excellence under these stringent standards, DBI ensures a carefully curated pool of top talent, where clients can make confident, data-driven decisions about creative partnerships.
Beyond its directory, DBI offers a comprehensive DBI Credibility Suite™ designed to help designers and studios stand out in an overcrowded market. Each DBI-rated professional receives authoritative certificates, digital assets, and rating logos that validate their skills and attest to their proven creative excellence. These tools seamlessly integrate into websites, social media, and marketing materials—reinforcing trust, credibility, and, ultimately, market value. Notably, DBI ratings remain valid for a two-year period, encouraging ongoing professional development and highlighting those who continuously push the boundaries of innovation.
By systematically reducing guesswork and eliminating reliance on subjective portfolio reviews alone, the Design Business Index creates a more efficient, trustworthy, and merit-based environment for both clients and designers. With DBI, top talent rises above the noise, clients gain peace of mind, and the entire global design community benefits from higher standards of creativity, innovation, and professional excellence.
Design Business Index champions design excellence, valuing official recognition from respected international juries over mere popularity. Our criteria focus on transparent, rigorous evaluations by peers, assessing quality, ethics, and innovation.
