[1] Waller was articled to the civil engineer and county surveyor for Gloucestershire, Thomas Fulljames (1808–74), who proposed him as a Fellow of the Royal Institute of British Architects in 1856.
He also designed a Tudor Revival extension that was added to the house at Great Tew Park in Oxfordshire.
[2] In London's Belsize Park he designed the house at 69 Eton Avenue for the artist John Collier.
In 1848 he drew a plan and sections of an historic barn at Shilton, Oxfordshire, that had stone walls and an aisled timber frame.
[3] Later the barn was reputedly gutted by fire[4] and at the foot of his drawings Waller added "All now destroyed".
