Thomas Ellis Owen (1805–1862) was an English architect and developer responsible for many of the buildings that still exist in Southsea and Gosport.

[1] He trained as an architect and, although his architecture was probably influenced by John Nash, Owen had a lighter touch that belonged more to his Georgian roots than the Victorian times he mainly practiced in.

Returning to England, Thomas married Catherine, the daughter of one of his father's colleagues J.W Higgins, surveyor of Government Works.

In addition, he designed a range of commercial, religious, and civic buildings, including St Jude's Church in central Southsea.

[7] In addition to his work as an architect and developer, Owen was a prominent civic figure.Owen's politics, like that of his brother-in-law Sir Charles Lanyon were instinctively conservative.

In 1835, Owen entered his name for election of the new Borough Council, perceiving a political biased because only Reform or Whig supporters were chosen.
