His first major work was the Wellington Monument, Somerset. Lee's further work was characterised as "eclectic" by Howard Colvin, who instanced the pared-down Soanean neoclassicism of Arlington Court, Devonshire (1820-23 for Col. J.P. Chichester), the Tudor Gothic Eggesford House, Devon (1822 for Hon. Newton Fellowes; now a ruin), several "Commissioners' Gothic" churches in Worcestershire, Cheshire and Staffordshire, as well as an unusually early neo-Norman one. In 1826 he designed the Guildhall in Barnstaple (finished 1828 and currently being restored) which makes an impressive frontage for the later Pannier Market.
