At the same time Di Fausto, whose prolificity was impressive, was continuing also his work in Italy, above all in Rome—where he owned a thriving studio—and surrounding regions, where, in the second half of the twenties, he designed several housing complexes: among them, those for the civil servants of the MAE, in Via delle tre Madonne, characterized by its Roman barocchetto style.
In 1926–28 he designed on the hill of Montelarice near Loreto the villa of the famous tenor Beniamino Gigli, a pretentious and luxurious mansion, whose interest lies in its plan with a central body and two tilted lower wings, a concept that Di Fausto would re-use several times in the future.
On 21 February 1930 he had a bad airplane accident in the northern Tyrrhenian Sea, being rescued together with his crew after 12 hours by the ship Citta' di Tripoli.
In the thirties, his most important works in Italy were the Centrale del latte (dairy plant) in Pescara (1932), where Di Fausto abandoned his eclecticism in favor of a clean functionalism, the Casa del contadino ("Peasant house") in the new city of Littoria (today's Latina) and the military sanatorium in Anzio (1930–33).
The latter complex, placed in scenic position in a pine wood in front of the sea and near the ruins of the Villa of Nero, is a good example of Italian rationalism.
Here is particularly noteworthy the chirurgic tuberculosis pavilion, with a central body containing the operation room, whose semicircular outer wall is a single glass façade.
From this body diverge two long angled wings which host the patients.
The Peasant house in Latina, with a central tower and strutting wings, was demolished in the sixties.
The dairy in Pescara, also demolished ın 2010 amidst much controversy and legal fıghts, was a three-body building upholstered with Clinker, whose central body façade had a treble glass wall.
The last two buildings were commissioned by the agriculture ministry, which gave to the architect several other works, like the organization of the national exhibition of wheat, reclamations and fruit picking, held in Villa Borghese in 1932, and the design of the main seat of the Fascist Agricultural Worker Union (C.F.L.A.), in Corso d'Italia, Rome, in 1936–37.
In that case, Di Fausto radically altered a pre-existing edifice, transforming it in a typical stile littorio building.
between 1937 and 1939 he erected in Via Agri, Rome, the Villino Staccioli, a classical example of Italian rationalism.
The Stacciolis, a family from the Abruzzi, were the owners of a building company which executed many among the architect's works in Italy and abroad.

In the same period, he was active also in Albania (at that time practically an Italian protectorate), where he replaced Armando Brasini.
There he designed the new city plan for Tirana, with the city center and the monumental department buildings around Skanderbeg Square, in Neo-Renaissance style with articulate angular solutions and giant order fascias (1932).
In the same years he designed also the royal palace of Durrës (1928–30), with a central tower and two wings, and the royal villa at Scutari (1928), both works being commissioned by King Zog I.
