It is distinctive design in the manner of Voysey, with white walls, green slate roof, and a canopy over the front door on curly iron brackets, and is one of Horsnell's few surviving buildings[2] While working in Chelmsford he won a travelling studentship from the Architectural Association.
He moved to London, where he worked at 2 South Square, Gray's Inn alongside Charles Gascoyne, George Nott, and Robert Atkinson.
[5] During these pre-war years, he worked as an assistant to Ernest Newton and drew perspectives for notable houses in Cheltenham (Greenway, Shurdington) and Lingfield (Ardenrun Place).
His unerring instinct in matters of taste enabled him to design in the manner of tomorrow rather than follow on the lines of yesterday, while his gift of brilliant draughtsmanship gave him the power of presenting his ideas in the most attractive form.
Had he lived till the end of the war to take up his work where he left it, there seems little doubt but that he would have won his way to a foremost place among the architects of the day.
