                         Professor Krisda Arunvongse began his office, Krisda and Associates in 1957 after being educated in the United States of America.  In less than twenty years, he had designed and constructed over a hundred of projects.  By 1974, there was an idea to find a new company name that would in itself explain the nature and services of the company.  The new name became CASA COMPANY LIMITED, short for Consulting Architect and Structural engineering Associates, which was registered on January 29, 1974.

                         In the beginning, CASA Co., Ltd. rented a small space on the fourth floor of a building on Rama IV Road.  There were only seven architects and a few draftmen and office personnel.  Production of drawings was still done by hand.  Ten years afterwards, CASA Co., Ltd. completed over thirty prominent landmarks including Manohrah Hotel (1970), President Hotel (1972), Central Department Store Main Office at Silom (1973), Central Department Store Chidlom (1977), Mahidol University Pre-medical Sciences Complex (1975), Songkla Nakarin University Medical School and Hospital (1978), Sindhorn Building where the 1st stock market exchange were located (1983), and Airport Hotel, Bangkok (1983).  In 1983, on the start of a new project, Charn Issara Tower, CASA Co., Ltd. had to make plans to move out of its office since the site of the new project meant the demolition of the building where CASA was located.

                         The new address for CASA Co., Ltd. was Sukhumvit Soi 4, in the compound of the residence of Professor Krisda himself.  A two stories, three hundred square meters office building was designed and constructed in 1983.  New amenities included a receptionist's space, administrative office, conference room, and model building room in addition to the architecture/production room on the second floor.  In the next few years, CASA Co., Ltd. designed the Asia Credit Headquarters (1984), Thai Airways International Headquarters (1987), Central Department Store Huamark (1988), IBM Building (1988), and Beauty Gems Enterprise Building (1989), were completed.  By this time, CASA Co., Ltd. became a synonym for Krisda.  Professor Krisda or CASA Co., Ltd. became known to all as the pioneer in high-rise building design in Thailand.

                         In 1982, Bangkok Bank Headquarters on Silom Road was completed.  At 32 stories high, it became the biggest and tallest office building in town.  Mahboonkrong Center (1988) was then the biggest commercial complex in the country.

                         By 1987, the office grew to about fifteen architects and over twenty other collaborators, and more projects were being added to the list.  The expansion brought about great effects not to mention the introduction of ten computers which added great speed to production.  Because this was the expansion stage for CASA Co., Ltd., new companies were being formed to support the original one including CASA Development Co., Ltd., a consulting and construction management company, founded in October of 1987 along with Arunvongse Co., Ltd. which deals with real estate management.  In October of 1990, CASA Khao-Yai Co., Ltd. was registered as a company dealing with resort development at Khao Yai, Thailand.  With all of the expansion, CASA Co., Ltd. and its brother organizations desperately needed to find a bigger office space.

                         The IBM Building on Paholyothin Road, designed by CASA Co., Ltd., became the next home for the company and its associates.  Space on the seventh, thirteenth, and eighteenth floors of about 1,000 square meters altogether was leased starting in 1990.  Almost twenty more computers were added.  However, not every company was based there.  This space was transitional in the sense that within three years the company would again move to another building of its design.  Some projects were finished during this time by CASA Co., Ltd. including Royal Gems Golf & Sport Club (1991), Tai Ping Factory (1991), CTI Tower (1992), and Silom Complex (1992).

                         In April of 1993, CASA Co., Ltd. finally moved to the eighth floor of Chamnan Phenjati Business Center on Rama IX Road, another project of its design.  This was the first time all the brother companies were organized together on one office floor space, and new additional companies were expected.  A&M Realty was registered in July of 1993 as consultants in real estate marketing and planning.  CASE Co., Ltd., short for Civil and Structural Engineers Company Limited, was registered in November 1993.  With more than thirty years of growth, CASA Co., Ltd. and the associate companies now utilize well over 1,600 square meters.  CASA Co., Ltd. today is one of the largest architectural firms in Thailand with a current professional staff of over thirty architects and a supporting team of over fifty other collaborators including CAD operators, model builders, interior project coordinators, and administration.  There are also over forty updated computer terminals connected to a local area network system.  Unfortunately, the suspension of a dozen major projects in 1997, due to economic crisis, resulted in a major reduction of staff in 1998.


                         CASA Co.,Ltd. has undoubtedly shaped the skyline of Bangkok.  Completions in the city are two of Bangkok's tallest high-rises, RS Tower (1993) which is forty-two stories high and United Center (1993) which is fifty-two stories high.  Many commercial centers were completed such as World Trade Center Hotel and Convention Center, Vibulthani Complex, Gaysorn Plaza, President Tower, Benchachinda Complex, Central Plaza Pinklao, Central City Bangna, and the biggest shopping complex in Southeast Asia, Seacon Square.

                         CASA Co., Ltd. has tackled every type of building in the past, and with the steady growth in size and experience, the company has also made many affiliations with local engineering firms as well as foreign consultants.  CASA Co., Ltd. today proudly offers a complete line of services including architectural, engineering, interior, landscape, urban planning, project administration, and construction management.  The company is fully prepared to assist the clients in a comprehensive design service, from master-planning the site and conceptual design to individual building design, preparation of specifications and contractors evaluation as well as construction supervision to the completion of the project and the follow-up services.


                         CASA Co., Ltd. also offers special services such as feasibility studies, research and information management, proposals, and presentation models and drawings.  Graphic, signage, sculpture, and monument designs are also the other types of services available.  CASA Co., Ltd. has aimed to provide the clients a total design service.

                         CASA Co., Ltd. strives to maintain the integrity in offering the best design, planning, technology, management, quality, and the most reasonable total project and construction cost versus timing.  The company intends to make strong efforts and contributions for better quality of the lives of people to improve the standard of living as well as the environment of the city as a whole.  Also, the concepts of aesthetic value with the most advanced technology available locally are pursued to be integrated with the concepts of functionalism.  Constant problems facing our design professionals give us practical experiences that will provide the best possible design solution.  CASA Co., Ltd. understands that to achieve a success, there requires a balance between good design and sound business administration.  In designing more creative and productive environments, the company has also addressed the recent "green" issue to better the landscape and ecology.  By practicing and developing new knowledge, CASA Co., Ltd. finds that it is the only way to give services of the greatest benefit to the clients.
