EJ Square Design Pte Ltd is a full-service residential and commercial interior design and build firm, founded by Indonesian designer John Susanto who resided in Singapore for 21 years. His career begins in 1999 where he worked at local architectural commercial and residential interior design firm for 4 years before opening his own design firm in 2003.

EJ Square Design’s philosophy is to create inviting and elegant interiors – straying from trends that will only disappoint in years to come. Their design approach is to architecturally space plan every square inch of a room to work both aesthetically and functionally. Each project is tailored specifically to each client, as John pays special attention to every detail that goes into project. Known for his incredible home and commercial renovations, challenges such as small spaces and embraced by John and his staff, as they creatively transform some of the smallest most unusable spaces to multi-functional rooms. EJ Square Design is committed to using sustainable materials, wherever possible.

Each project begins with an in depth personality study with client before design options are explored. This result in sensually sculpted interiors that speak of intimacy and indentity all at once.

We assist to build upon a client’s values, positioning, target market and put them into practical use. Offering a space that will connect with people creating dream spaces work, life and play.

Mr. Susanto’s works has been featured on Mediacorp’s home variety programs and Singapore local magazines.


EJ Square Design’s mission is to ensure customer satisfaction with full commitment to comply with requirement and continual improvement in our quality assurance and provision of value of money services and finished products.
