Her initial success came as a designer of restaurants. In fact, Fadillioglu designed over 20 establishments that can still be found in such cities as London, New Delhi, and Abu Dhabi. However, Fadillioglu is best known as the first woman to design a mosque. In 2009, Fadillioglu received international acclaim when she unveiled the Sakirin Mosque in Turkey. Uniquely, Fadillioglu made sure that the mosque honored women by ensuring that both the men’s and women’s upper galleries were equal in terms of both size and beauty. Over the course of her career, Fadillioglu has been awarded with a number of honors, including the Andrew Martin International Designer of the Year Award (2002), the House & Garden International Interior Designer of the Year (2002), Modern Designer of the Year Award (2005), and The Wifts Foundation International Visionary Award (2011).
