As a long-serving member of the Brighton School of Art—where he was head of the Architecture department—he also influenced the careers of former pupils who were later associated with the large group of artists who lived and worked in nearby Ditchling, where Cribb was based.

English Heritage has awarded some of Denman's works listed status in view of their architectural importance: among them are an elaborate Byzantine Revival mausoleum, an "elegant" Neo-Georgian office building and a pair of ceremonial stone pylons on the city boundary.

)[13] Another early work was his redesigning and substantial extension of the Sussex Masonic Centre at 25 Queen's Road, next door to his father's office, in 1928.

[20] In 1930, Denman took over his father's architectural practice at Queen's Road,[2] and over the next few years he was commissioned to design several major commercial buildings in Brighton.

His Neo-Georgian offices for the Citizen's Permanent Building Society on Marlborough Place were finished in 1932,[3] by which time construction of the Richmond Hotel and bar had started.

[23] On side roads off North Street in the town centre, Denman designed Neo-Georgian offices for the Brighton & Hove Herald newspaper in 1934[24] and Regent House—in a similar style but with angular Modernist elements—in the same year, immediately behind the Chapel Royal.

[29] Denman also undertook small schemes to design internal features and fittings for buildings, such as his work at Preston Manor.

[33] During the 1940s, Denman's work was exhibited at the Royal Academy of Arts, and locally he served as a Justice of the Peace in East Sussex.

Among other things, he noted that he was summoned by the Bishop of Chichester George Bell in the early 1950s to discuss proposed designs for a permanent church at Peacehaven, a rapidly growing residential area east of Brighton which only had a temporary building for worship.

Bishop Bell disliked the first submission, by a builder with no architectural training; Denman advised him to reject it and a second design submitted by another man.

[38] This Kemp Town Brewery pub is a "striking" and distinctive Arts and Crafts/Sussex Vernacular building on a prominent corner site.

[41] Councillor Sir Herbert Carden commissioned these "wedge-shaped" stone structures to flank the main London Road at the boundary of the newly extended Borough of Brighton in 1928.

Carvings and inscriptions include the coat of arms of the Duke and Duchess of York, who laid the foundation stone, the emblems of Brighton and Sussex, a female figure and a galleon.

Details of the date, architect, builders, founders and other descriptive information, and a short poem, are also carved on the flat panels which are mounted on the concave faces.

[45][46] Sir Herbert Carden again commissioned and partly paid for this seat on the South Downs above Brighton, on a 190-acre (77 ha) area of land he had bought for £9,000 to preserve for posterity.

There is a cornice interrupted by rounded mouldings, an arched entrance flanked by columns with decorative capitals and a recessed bronze door.

[1][3][50] Principally Neo-Georgian in style, this office has some Modernist elements: "modishly angular canopies" above its irregularly placed oriel windows (which are of the Crittall steel-framed type), and curiously patterned brickwork giving the impression of pointillism.

[1][26] Built by Denman for the Kemp Town Brewery, this prominently sited suburban pub has stone decorations on its façade, described as "peculiar stylised urns surmounted by ... a squat burst of flames".

Dark brick and red roof tiles from the Ringmer brickworks were used in the design, and there are three "startling" carved stone reliefs on the exterior: Saint Christopher, a pelican and a lamb.

[62] Denman's church for the Whitehawk housing estate in the east of Brighton replaced one built in 1937 and destroyed by a World War II bomb six years later.

[67] Denman designed a replacement for the Quaker community's original meeting house, which had been destroyed by a bomb in World War II.

A "strongly built" seven-storey block of flats with elements of Modernism, it consists of two parallel street-facing towers whose corners are recessed in stages, joined by a five-storey bow-fronted section.

[68][69] Described as "typical of their work at the time", this flint and brick church in a postwar suburb of Hastings was designed by Denman and his son and was built over the course of several years.

[1][6][71] This hall-style church with brick and flint walls with domestic-style windows and a rounded projection at one corner has been attributed to Denman on stylistic grounds, but no records exist to confirm this.

[74] Denman attached a Masonic Temple and its associated offices to the side of an 1830s Classical-style house attributed to Amon Wilds and Charles Busby.

He built on to one side and the rear, increased the height by one storey and redesigned the interior with ornate Masonic decoration and panelling.

[21][75][76] Denman's "famous facelift" of this mid 19th-century corner-site restaurant, a plain stuccoed Classical-style building, has been described as "spectacular",[77] "striking" and "reminiscent of the Viennese Secession".

"It is virtually certain" that Denman carried out the refurbishment, which was undertaken soon after his work at the Railway Inn in Eastbourne and which shares many design features with that pub.

[84] Denman's work at this long-established department store, now closed, included an extension to the rear featuring a series of round-headed windows and a hexagonal turreted tower.

[86] This ancient church was rebuilt in the 19th century and greatly extended by Denman when West Blatchington—originally a sparsely populated Downland farming area—became a residential suburb.
