In Belgium Veldeman built an aluminium tennis hall of 36m by 50m which covers 3 tennis courts. New in this polygone hall is the automatic curtain of 27m long and 3m high in both gables which can be completely rolled up in only 90 seconds. In summer the open side walls create an outdoor sports feeling, while in winter the closed side walls offer protection against the cold, wind, snow and rain.

In Ireland Veldeman built a steel 3 court indoor tennis structure with extra insulation. With regard to insulation, an additional fabric was provided for roof, gable and side walls. In addition, an insulated steel plate was placed on the outside up to a height of 3m. The tennis hall was provided with a viewing platform and storage area.
