The building is arranged to accommodate a range of different size gallery spaces each with a variation on the way natural light can be introduced.

The basement includes a working archive and gallery with variable natural and artifical lighting options and close temperature and relative humidity control.

A sub-basement was introduced to house air handling units necessary for the close environmental control required in each gallery.
Mechanical ventilation systems controls the environment to provide appropriate conditions for conservation.

Ventilation ductwork has been arranged in vertical routes between the existing timber joists being retained and left exposed.

Visible elements of the buildings servcing have been devloped to sit neatly within the cast concrete finishes

The lighting of the main stair is intentionally minimal. Iterative light modelling gave confidence in our approach with selected light fittings providing both general and emergency escape functions.

Daylight is controlled in the gallery spaces with motorised diffusion and full black-out blinds.
