Among his works are the temple-like Storm Water Pumping Station, Isle of Dogs, London (1985–88), the New House at Wadhurst Park, Sussex (1978–86), the Judge Institute of Management Studies in Cambridge (1995), and the Computational Engineering Building (Duncan Hall), Rice University, Houston, Texas (1997).

[4] In the mid 1980s, the London Docklands Development Authority awarded contracts for three storm-water pumping stations to Richard Rogers, Nicholas Grimshaw, and Outram.

Outram designed the Isle of Dogs Pumping Station, a "monumental temple"[6] with which he hoped to situate the viewer "within a Landscape of Symbols".

Services, along with access ladders, were placed inside hollow pillars and incorporated within what Outram has called the ‘Robot Order’ (Ordine Robotico).

"[10] Other buildings include Sphinx Hill in Oxfordshire (1999), Craft Workshops, Welbeck Abbey, Nottinghamshire (2000), and a retail development at the Old Town Hall, The Hague, The Netherlands (2000), in which Egyptianizing, Classical, and other historical references are "treated with verve and imagination"[11] National Life Stories conducted an oral history interview (C467/86) with John Outram in 2007 for its Architects Lives' collection held by the British Library.
