Law's greenhouse space grew to , and his roses earned up to $100,000 each year. As many as 8,000 roses were shipped from Briarcliff Greenhouses daily, most of them to New York City. In 1902, Law built the Briarcliff Lodge on the highest point of his estate; it was the first hotel in Westchester County. Law also developed the village, establishing schools, churches, and parks. He donated land for the Briarcliff Congregational Church (built in 1896) and for Liberty Park (later dedicated as the Walter W. Law Memorial Park); in 1900, he established the School of Practical Agriculture on Pleasantville Road on of land. He also built Dysart House as a guest house in 1897, named after Dysart House in Scotland. By 1902, Law had invested $2.5 million ($ in ) in the village. In 1906, he replaced Briarcliff Manor's railroad station with the present-day public library. His employees at Briarcliff Farms moved into the village in its early years, and Law held some of their mortgages. At the time, New York State required a population density of at least 300 per square mile for incorporation as a village. A proposition was presented to the supervisors of Mount Pleasant and Ossining on October 8, 1902; it requested that the area, which had 640 acres with a population of 381, be incorporated as the Village of Briarcliff Manor. The village was incorporated on November 21, 1902. At the time, Law owned all but two small parcels of the village, and he employed 100 of its residents. Law largely developed his Briarcliff Manor property as a business corporation until 1907, when he purchased for Briarcliff Farms in Pine Plains, New York; he then began developing his properties for houses, churches, and schools instead. In 1909, Law formed the Briarcliff Lodge Association to run the hotel, and the Briarcliff Realty Company to sell the original Briarcliff Farms property. His son, Henry, presided over the realty company until 1936. In 1908, during the Briarcliff Manor-sponsored First American International Road Race, Law donated and presented the Briarcliff Trophy, valued at over $10,000 ($ in ). In 1918, Walter Law sold his Briarcliff Farms land in Pine Plains. Later life
