A landmark in the Marconi-Alexandra neighbourhood

Upon construction, 400 Atlantic’s ten-storey structure immediately became a landmark in the Marconi-Alexandra neighbourhood, known today as Mile-Ex. 400 Atlantic has the attributes of light industrial buildings, which can satisfy the needs of the most discerning office users: high ceilings, abundant natural light, exposed structural frames, interior brick and hardwood floors. Over a century after its initial construction, 400 Atlantic has undergone an uncompromising modernization, resulting in the transformation from light industrial to Class-I office. It offers 10,000 SF floor plates with ensuite elevators. The redevelopment is aiming for LEED Gold Certification, reinforcing Allied’s environmental commitments while supporting those of our users.
