A method for constructing an elevator system in a building includes performing at least one lifting operation to adapt a usable lifting height of the elevator system to an increasing height of the building. A drive platform supporting an elevator drive machine and, by a flexible support, an elevator car and a counterweight is raised during the lifting operation. A difference between an elevator-car-side support weight and a counterweight-side support weight is substantially compensated by a compensating tension device guided from a bottom side of the elevator car to a bottom side of the counterweight by a deflecting device including two roller assemblies having deflecting rollers forming a compensating tension loop. A distance between the roller assemblies is reduced before and/or during the lifting operation such that an amount of the compensating tension device required for the performance of the lifting operation is released from the compensating tension loop.
