Mawson describes meeting Freeman in his “Life and works of an English landscape architect: an autobiography”. “It was at Bryerswood that I first met Colonel Sandys whose large property at Graythwaite adjoined [Bryerswood]. I also met here Mr Knill Freeman, the well-known Bolton architect, who designed both Bryerswood and the new additions to Graythwaite Hall,” and: “I visited the work at Graythwaite three days a week. Whilst at Graythwaite I often met Mr Knill Freeman and his resident architect, Mr Dan Gibson. Mawson later went into partnership with Gibson.
