Expansion meant that the college made increasing demands on George Heriot's Trust throughout the first part of the 20th century, which ultimately led to the independence of the two bodies in 1927. While the Trust continued to pay Heriot-Watt a fixed sum each year, from then on the college was responsible for managing its own financial affairs.[1] Heriot-Watt continued to expand after becoming independent, opening a new extension in 1935.[2]: 243
