About Us

We produce great ideas and build new world

Sara Kalantary and Reza Sayadian are practicing architects who founded TDC Office in 2002.

What differentiates them is the answers they give to the world around them, and a humble view, yet critical is easily traced in their works. Such view can be observed in numerous projects where unique solutions are rendered compared to typical methods of design and construction.

Respect for human being and habitat, and a constant search for finding appropriate ideas, are based on the fact that creating a world full of unique recommendations can alter people’s deduction towards possible phenomena.

For them, Architecture is a dynamic phenomenon. They look at it as part of the city so that it can create memories. Dynamic presence of human in the city and home, as well as the flow of life in them are the most invaluable part of creating a space which insinuate that architecture is the way to embrace the world.

Sarah and Reza’s works, with their unique approach and ideas, have managed to win several international as well as national awards. Students as well as university professors have also taken notice of their work, both inside and outside the country. Such occurrences have resulted in their works being published in many authentic books and magazines all around the world.

سارا کلانتری و رضا صیادیان در سال دو هزار و دو با تاسیس دفتر معماری تداوم پویا همکاری و فعالیت خود را در حوزه عملی معماری آغاز کردند.

رویکرد متفاوت آنها در پاسخ هایی است که به جهان پیرامون خود می دهند و نگاهی انسان گونه و در عین حال انتقادی در آثار آنها دنبال می شود.رد پای این نگاه انتقادی را می توان در چندین پروژه که نسبت به متداول ترین گونه های طراحی و ساخت،راه حل های متفاوت ارائه داده است دنبال کرد.احترام به انسان ، بوم و بستر و جستجوی مداوم در پی یافتن ایده هایی مناسب، بر پایه این باور است که خلق جهانی سرشار از ایده های ناب می تواند برداشت مردم شهر را نسبت به پدیده های ممکن تغییر دهد.

برای آنها معماری پدیده ای است پویا، آنها به معماری به عنوان بخشی از شهر می نگرند تا بتواند خاطره سازی کند.حضور پویای انسان و جاری شدن زندگی در شهر و خانه با ارزش ترین بخش خلق فضاست، آنچنان که این دو بر این باورند که معماری یعنی شیوه در آغوش کشیدن جهان.

آثار سارا و رضا با نگاه متمایز و ایده های متفاوت برای خلق فضا، موفق به کسب جوایز متعدد داخلی و بین المللی شده و همچنین در دانشگاه های مختلف داخلی و خارجی مورد توجه دانشجویان و اساتید قرار گرفته است،این رویکرد باعث انعکاس آثارشان در مجلات و کتابهای معتبر جهانی نیز شده است.
