Hamilton Place - Ontario - Canada

Abstract

Although comparatively modest as to its exterior, the interior of the theatre-auditorium Hamilton Place has been most successfully solved, both as regards design and acoustics. Construction techniques and elements have been utilized to achieve two different sections in one and the same hall with on one hand the capacity to be able to capture shades of the spoken word at theatrical functions and on the other to reproduce the sharpness and variety of orchestras and choirs. The following elements deserve special mention: the mobile wall which incorporates the orchestra into the hall by closing the proscenium arch; the two elevating platforms where the orchestra is placed; the vertical velvet surfaces, hung like banners which soften the repercussion of the sound; the mobile horizontal surfaces over the orchestra that direct and orient the sound. The most interesting construction techniques are: the subdivision of the building into different parts, each one with independent foundation so as to avoid the transmission of the sound from one section to the other; the texture of the brick walls that disperse the reflected sound; and the use of counterforts to create smaller more personal sections for varied use. The acoustic characteristics are improved by means of a sound installation, formed by small loudspeakers placed under each seat and by other bigger ones distributed in the walls that surround the hall. The building is completed by various service installations that are appropriate to this type of construction, as well as by a small theatre-studio for the rehearsals of the orchestra and the actors, while other functions are going on in the main hall.
