Hamphrey Tedja and Santi Alaysius

Principal and Co-Founders


As the scion of one of Jakarta's real estate developers who was blessed with limitless creative flair, Hamphrey is a natural fit for the architecture and interior design industry. He has spearheaded and contributed to all types of project designs from residential – subdivisions, multi-unit and single family – to commercial – highrise offices and shops – to hospitality – restaurants, hotels, and bars – throughout his career of over a decade, which has spanned across the world from the United States to Southeast Asia.

Hamphrey is a rare professional who has the technical ability of an architect, but who is also fully capable of executing the design of a project down to the last throw pillow without making the space look or feel sterile, cold or overly architectural. He also has the uncanny ability of a bloodhound to find a way to obtain or manufacture any parts or pieces that may be needed to make a design concept truly sparkle. He is not only a creative talent, but also a tirelessly patient project manager who has a knack for creating synergy within a project team of even the most diverse and conflicting personalities, and the tenacity to follow through until every last detail on a project is taken care of properly.

Hamphrey studied at the world-renowned Illinois Institute of Technology in Chicago where he earned a Professional Bachelor's Degree in Architecture. He worked for a couple of Chicago based commercial and residential development firms as well as doing corporate interior and hospitality work in Chicago before returning home to co-found Domisilium Studio in Jakarta in 2009.


Growing up around her father’s bustling design-build office, Santi came into the construction industry quite naturally. She has been an award-winning professional Interior Designer for over a decade. During that time she has won multiple awards for her design work on the Waldorf Astoria Hotel Chicago (rated #7 in the world by Condé Nast), along with an award for a restaurant project, and her work has been featured in numerous design publications such as Wallpaper UK Magazine, Hospitality Design Magazine, Interior Design Magazine, Elle Décor and Home & Décor, among others. She has worked on many additional high-profile projects such as the USA Pavillion for World Expo 2005 in Japan, the residence of superstar Jennifer Lopez in Long Island, NY, USA and the first design hotel in Indonesia, Kosenda Hotel.

Santi is an expert in creating uniquely beautiful spaces while selecting the finest local materials available for them, and has an unrelenting eye for perfection in every detail. She has the rare capacity to work flawlessly across all project types and design styles, carefully extracting the desired mood from her clients and creating spaces with style, class, precision, and flourish. She specializes in translating other art forms, such as fashion, art and industrial design into interior design components and themes, creating new design ideas from oftentimes familiar objects. Her and her design firm named as one of the A-list Interior Designers in the country by Elle Décor Indonesia Magazine in 2013. Her firm has done design for International brands such as Nike, Marriott International, Time International, Accor and Martha Tilaar Spa.

Santi attended The Art Institute of Seattle and Illinois Institute of Art-Chicago where she received Bachelor of Arts in Fashion Marketing Management with High Honors and Bachelor of Fine Arts in Interior Design. Santi honed her craft at Thom Filicia, Inc in New York and Simeone Deary Design Group in Chicago doing highend residential and hospitality work before co-founding Domisilium Studio in 2009. Santi is fluent in Indonesian and English, with some conversational knowledge of Chinese and French.
