IRVING, TEXAS — Varidesk, a provider of adjustable desks, has acquired a 424,000-square-foot office building located at 901 W. Walnut Hill Lane in Irving’s Las Colinas district. The three-story building was built in 1983 and formerly served as the headquarters of jewelry retailer Zales. Amenities include a fitness center, cafeteria and conferencing facilities. The new ownership will reposition the building with a design that activates the entry plaza, promotes connectivity to the outdoors and modernizes the amenity spaces. Cushman & Wakefield is working with Varidesk on the redevelopment and lease up of the building. Corgan is the architect and interior designer for the new office space, which is expected to open this summer as VARISPACE Las Colinas.
