The south facing façade of the Neo-Georgian main school building. The interior of the building was planned around a central two storey hall with galleries giving access to classrooms. The building was designed by architects Connon and Chorley, and opened by Princess Louise on the 29th September 1906. Connon and Chorley were responsible for several other impressive buildings including the Metropole Hotel in Leeds, and the Grand Hotel in Sheffield.

The following are extracts from Helen Jewell's book "A School of Unusual Excellence" (1976) :

"The contractors for the new building were William Airey and Sons, whose combined tender was £16,750. A press report explained that the building was to have three storeys, with a large two-storey hall, all classrooms facing south, physics and chemistry laboratories, art studio and modelling room, gymnasium, cookery laboratory, and large dining room."

"The next important occasion was the laying of the Foundation Stone of the new school in Headingley Lane, by the Lord Mayor, Mr Robert Armitage, on 10 July 1905. Preparations had been put in hand almost as soon as the tender for the new school was accepted. Alderman Ford, Chairman of the governing Committee, made a speech about the School's history, and the Head Mistress, Miss Joseph, gave an address. The hymn 'Now thank we all our God' was sung, and the psalm 'Except the Lord build the house' chanted, the girls' orchestra supplying the accompaniment, and the stone was ceremonially laid. The architect, Mr H. S. Chorley, gave the Lord Mayor a trowel, and the contractor, Mr Edwin Airey, gave him a mallet. The Lord Mayor made a speech, and the Chairman of the Leeds Education Committee, Mr Kinder, congratulated the High School Committee on the site and hoped the promise of the buildings for September 1906 would be kept. Dr Dufton, Chief Inspector of Secondary Education for Leeds and District, remarked that girls' high schools tended to disregard the domestic side, and that the inclusion of a cookery room in the plan therefore pleased him. Professor Banks proposed a vote of thanks, seconded by Alderman Tetley, and after the formal proceedings, which had lasted a full hour, the company had afternoon tea 'in the workmen's shed at the back of the old house'. The girls were grouped round the school violinists, in white dresses and green school ribbons. Heavy cloud covered the sky, but rain held off until evening. A sealed bottle of documents was placed under the stone by the Head Girl, Margaret Hauptmann".
