THE Hongkong Institute of Architects has announced its annual awards for outstanding design for last year. The jury felt that none of the schemes had exhibited the level of excellence required for the Award of the Silver Medal, although a number had shown competence in architectural design. Of a total of 31 projects submitted, six were shortlisted. Three received the Certificate of Merit and one the President's Prize. Winners of the Certificate of Merit included the Kwong Yuen Estate Commercial Centre, submitted by the Hongkong Housing Department's Construction Branch. The other winners were Visual Arts Centre at Hongkong Museum of Art, by Wong Tung & Partners, and the Royal Hongkong Jockey Club Happy Valley Clubhouse, by RMJM Hongkong. The President's Prize went to the Jockey Club Box at the Royal Hongkong Jockey Club Sha Tin Racecourse, designed by Leigh & Orange. The jury, consisting of five architects and one lay person, felt that the Kwong Yuen Estate Commercial Centre had an overall atmosphere of strong local identity. The Visual Arts Centre, according to the jury, had produced an interesting and satisfactory re-use of an old building on a difficult site, with the innovative solution of an illuminated circulation spine connecting the multi-level building and the new extension. The Jockey Club Happy Valley Clubhouse impressed the jury with its ''external massing and form and the expression of the historical aspects of the horse racing tradition''. The Jockey Club Box at Sha Tin racecourse was a complex problem which had resulted in an innovative use of an awkward level of space on an existing roof deck, the jury said. It had produced an exciting interior space which made full use of both natural and artificial light.
