The mass of the building does indeed attract us upward slightly, which can cause a very small reduction in the weight we feel due to the gravitational attraction between our bodies and the mass of the building. This effect is a consequence of Newton's law of universal gravitation, which states that every mass attracts every other mass in the universe. The effect is extremely small but theoretically measurable.
