The architectural bureau PHD — Philosophy of Design — was founded in 2003 by the architect Lana Grineva. The bureau works on projects where the scale and proportions can vary significantly, from the design of furniture and interiors to architecture and monumental design. The company’s projects include country residences and private gardens, hotels and restaurants, representative offices, the interior of a motor yacht and aircraft. The bureau works all over the world and has implemented some of its projects jointly with global design stars: Christian Liagre, Enzo Enea, Rémi Tessier and Made Wijaya.
