The architect of the building was Charles Wyman Buckham, the son of the 11th University of Vermont president Matthew Henry Buckham.
 An 1891 graduate of the University of Vermont, Charles Buckham continued his architectural studies at the National Academy of Design (currently known as the National Academy Museum & School) in New York City, Columbia University, and at institutions in Paris.
 He was the designer of the State Office Building in Montpelier, Vermont, among a number of other notable buildings in Vermont, New York City, and Minnesota.

Morrill Hall is a three-story building (including a basement) built using rusticated brick with terra-cotta trim.
 From a centered and (generally) west-facing, semi-portico structure extends the main entrance, which is topped with a pediment adorned with the Great Seal of Vermont.
 The entrance way is adjoined by two 23' 3" granite columns; each weighing about thirteen tons and measuring a diameter of 2' 10" at the base, and 2' 5" at the summit.
 The steps to the front door are built from Woodbury granite.
 The wide sixteen-step inner staircase ascending from the main entrance to first floor is made of marble and complemented by walls of carved paneling.
 The wooden floors on the upper-levels are made of North Carolina pine.

The building has a length (north-south) of 112 ft.
and a width (east-west) of 62'.
 The total floor area is 28,169 ft² (gross area) and 19,574 ft² (finished area).
 An unfinished attic accounts for 6,944 ft² of gross floor space, which is primarily used for storage.

A 2000 UVM Historic Preservation Program report describes Morrill Hall as a "Neoclassical style building"
"Three stories in height, including a tall basement, it is rectangular with a widely overhanging, flared, and bracketed hipped roof of red Spanish tile.
The building is faced with American bond yellow brick with a random rusticated rock faced sandstone ashlar foundation (with tinted mortar), and molded brick water table.
The main block extends three bays to either side of the central pavilion.
There are seven bays on the rear of the building and four on either end.
All windows, except as noted, are paired, one-over-one, double hung with aluminum storm sash.
Second story windows on the front facade and both ends have arched tops."

A 1956 architectural analysis report further describes Morrill Hall as "late Victorian Eclectic" with its balance of structure and some of the window arches having a "Palladian influence":
"The stress placed by the architect on the entrance is reminiscent of the Baroque, although the rest of the building has none of the distortion of most examples of that style.
 In addition to emphasizing the entrance by projecting it forward, Buckham added two massive Ionic columns which flank the main door.
 Here he borrows from the Classical Revival era but provides his own touch by resting the columns on brick supports which rise several feet above ground level.

The roof is a somewhat modified Mansard type which is found in the Second French Empire style.
The roof design aids in preserving the proportions of the building and avoiding a top heavy look.
 There is a three foot roof overhang all around the building which suggests a 'capped' effect."

Emergency exits are mounted on the rear of the building which traverse the central bays of the second and third stories.
 Open steel grated stairways and railings are assembled with horizontal platforms positioned at each exit, and at a halfway point between each level.
 The emergency exit doors are primarily made of glass with sidelights and transoms.
