Clough's design work was varied throughout his career; from the house of Mayor Arthur B. Chapin to the two main commercial blocks of Dwight and High Street, he and his firm maintained a noticeable presence in Holyoke, with additional work in other Connecticut Valley towns focusing on residential architecture. One of his earliest and most prominent works was a
marble-clad hotel for local engineer and businessman John Delaney. Delaney's Marble Block, or the Marble Hall Hotel as it was often called, was designed by Clough and constructed in 1885. Withstanding a fire in 1902, and several smaller, the building stood at the corner of High and Dwight Street across from
City Hall for more than 60 years, until it was razed in 1950 to make way for the more modern two-story storefront which stands there today. File:CloughCapital.png|

Originally called the Ball Block for druggist Charles Ely Ball who operated his store out of there, the block was built in 1898. During the 20th century the building saw its first two floors modified extensively for the
Holyoke National Bank which moved into the building in 1915, and subsequently modified it to its present appearance. In 2005 it was renovated by the New England Farm Workers' Council and rechristened The Latino Professional Building, receiving an award from the
Massachusetts Historical Commission for its attention to original detail. The building's architectural details show influence Clough drew from
Italianate palazzo style architecture, notably in its pillared corner windows, ornate
capitals and
cornices. Clough also designed smaller Holyoke commercial blocks on High Street as well, including but not limited to, the Clough Building at 245 High Street, and the Baker Building at 368 High Street. The former is also known as the Russell-Osborne building as Clough leased it to the homonymous hardware store, while the latter was built for its namesake's stove and furnace business.
Richardsonian Romanesque influence can be seen in Clough's commercial work, through the use of
quarry-faced ashlar in broad arches on the second-stories of both buildings. Boston architectural historian Roger G. Reed also notes in his brief piece on Clough's work, that the use in arched windows on the second stories of such buildings may have been an aesthetic to indicate those floors were part of the storefront businesses at the time, however both buildings have seen their storefronts heavily modified and no original floor plans have been found to confirm this. Both buildings were constructed around the same time, with the Clough Building being constructed circa 1885, and the Baker Building completed in 1886. One significant departure between the two is Clough's use of a single dormer roof in his own building, along with a
slate front facade evoking a pitched roof, whereas the building's structural roof is flat. Clough also worked on multiple public spaces as well, including the
Holyoke Canoe Club, which was built in 1898 in an Italianate style with towers, a
stucco exterior, and four ornate towers at its corners. Though the towers have since been removed, the rest of the building endures today as a fixture in
Smith's Ferry. It could be argued that Clough's most memorable legacy can be found in
Holyoke Public Library building. Constructed in 1902 during the administration of Mayor Chapin, one of his previous clients, Clough donated his services to the city entirely
pro bono, as his daughters had been patrons. The last major work attributed to Clough was one he also designed without pay; the Holyoke Home for the Aged was organized by the druggist C.E. Ball's wife, Elvira Fales (née Whiting), and constructed in 1911. The facility continues to serve senior citizens today as the Sarawood Retirement Community. ==Selected works==
