The Sloyd room should be nothing of a "workshop". It should not under any circumstances be in the basement floor, as still is the case on many places, being a reminiscence from the "workshop" ideas of the older school. The Sloyd room should on the contrary be even more light and airy than any of the other class-rooms, with the exception may be of the gymnastic hall. For the bodily work, that is carried out in the Sloyd room, promotes naturally a deeper respiration than is the case with other sort of school work, and consequently the air that is inhaled must be of as good quality as possible is obtainable for a class-room. Also for the sake of preserving the models, the material, and the tools it is indispensable that the Sloyd room should be free from dampness.

If during winter time the Sloyd room is heated, the temperature of it should by no means be so high as in the ordinary class-rooms. The physical exercises caused by Sloyd work give warmth enough without much artificial heating. At any rate the Sloyd room should never be kept warmer than the gymnastic hall.
