He trained under his father, William Hurst Ashpitel before setting up his own practice in 1842, and working in partnership with John Whichcord Jr. between 1850 and 1855.
He was educated at Dr. Burnet's school in Hackney (see Sutton House, London) and trained as an architect under his father, but two childhood accidents damaged his health, and he did not set up in practice until 1842.
In 1845 he built the church of St Barnabas at Homerton, a Gothic Revival design in Kentish ragstone, fitted, unusually for the date, with gas lighting.
[1] Ashpitel was also responsible for design of the "Wellington Testimonial" a clock tower erected at the southern end of London Bridge in 1854, but removed soon after as an obstruction to traffic.
[1] In 1861 he designed a Venetian Gothic facade for a public house in Red Cross Street in the City of London, described by Wyatt Papworth as "probably the first attempt to render the mediaeval style appropriate for such a business".
[1] In 1861 he rebuilt St Mary's Church, Ripple, Kent, on its original Norman foundations,[1][4] in a Romanesque style, in imitation of St. Nicholas, Barfreston.
His last work was a design for twelve almshouses at Clewer, near Windsor, built at the cost of one of his sisters; they were constructed after his death under the supervision of John Whichcord.
[1] He revised Peter Nicholson's Carpenter's New Guide[8] and several other professional works for the publisher John Weale.
