Pennethorne was born in Worcester, and travelled to London in 1820 to study architecture, first under Augustus Charles Pugin and then under John Nash. Pennethorne's father, Thomas was a first cousin of Nash's wife.
In October 1824 he set off on a tour of France, Italy, and Sicily. At Rome he studied antiquities, and made a design for the restoration of the Forum, which he subsequently exhibited and was elected a member of the Accademia di San Luca.
Until 1840 Pennethorne engaged in some private practice, his works including the Bazaar, in St. James's Street; Swithland Hall, Leicestershire; Dillington House, Ilminster; St. Julian's (a house at Sevenoaks); and Christ Church, Albany Street. During this time he also began the work for the government, which would come to dominate his career. In 1832 he was directly employed by the Commissioners of Woods and Forests to prepare plans for further improvements in the capital. One of his aims was to form a great street running from the extreme east to the extreme west of London, but this proved too ambitious for the government. However four streets were constructed to modified versions of his plans: New Oxford Street, Endell Street, Cranbourn Street and Commercial Street. In 1846 an act was obtained for the extension of Commercial Street from Spitalfields Church to Shoreditch, but this was not completed until 1858. In 1855 the newly formed Metropolitan Board of Works constructed Garrick Street, Southwark Street, Old Street to Shoreditch, and other thoroughfares from Pennethorne's earlier designs.
Public works
After 1840 Pennethorne's time was wholly absorbed by his work for the government. In that year he was appointed (with Thomas Chawner) joint surveyor of houses in London, in the land revenue department; in 1843 he became sole surveyor and architect of the Office of Woods, and was appointed a commissioner to inquire into the construction of workhouses in Ireland. In 1847 he drew up designs for the Public Record Office in Fetter Lane. A much modified version of the scheme was adopted in 1850, though only portions of it were ever built. In 1848 he modified Nash's Quadrant in Regent Street, removing the colonnade and inserting a balcony and mezzanine story. In 1852 he worked on improvements to Buckingham Palace and the area between St. James's Park and the Royal Mews. His works at the palace included the ballroom, supper-room, and connecting galleries. To the south of the palace he erected the Duchy of Cornwall office, the district post office, and other buildings. Between 1852 and 1856 he completed the New Wing of William Chambers' Somerset House. which was never carried out. He was one of the architects invited, in 1862, to submit designs for a memorial to Albert, Prince Consort, but his suggestion for a monument in the form of a Classical mausoleum was rejected in favour of George Gilbert Scott's Gothic construction. Unbuilt plans commissioned from Pennethorne included designs for new public offices in Downing Street, and a new War Office intended to be built in Pall Mall.
His pupils included Henry Saxon Snell (1830–1904). His brother John Pennethorne (1808–1888) was also an architect.
He died on 1 September 1871 and was buried on the western side of Highgate Cemetery.
