ALEXANDER* A lecture delivered before the Society on 13th April 1966. Synopsls•The planning of a new laboratory devoted to research on toilet preparations is described, and details are given of construction, services and furnishings. A lecture on the planning and equipping of a cosmetic laboratory has previously been delivered to this Society (1). The speaker then said he had been involved in the designing of six laboratories. You will understand therefore that with this in mind, I feel somewhat diffident about my talk because I cannot claim to have the experience of the design of six labora- tories behind me! Nevertheless, as our experiences in connection with the new laboratory at Isleworth are likely to be paralleled by any one who has the good fortune (or misfortune!) to be involved in planning a new laboratory, I hope that at least some of the points covered in the lecture will prove of interest to you. In 1960, Unilever decided that the Isleworth site of some 4{• acres which was then occupied by the A. & F. Pears soap factory, would be redeveloped to accommodate a laboratory devoted mainly to research on toilet preparations. As some of the existing buildings already housed laboratories, we had to consider the redevelopment of the site as a step-wise operation and my lecture is mainly concerned with our experiences during the first stage of the project which has extended over some five or six years. The ultimate development as planned will comprise three main laboratory blocks, each 300 feet long and 45 feet wide, with the main laboratory accommodation on the three floors above the ground floor which is largely open-planned. Connecting these blocks at ground level is accommodation *Unilever Research Laboratory, Isleworth. 41
