HMFH designed the renovation of the former Lowell Trade School located in the city's downtown historic district to house two unique K-8 magnet schools--the Arts School and the City School. The Arts School curriculum is built around dance, painting, sculpture and drama. The City School is organized as a micro-society with its own banking and currency system, newspapers, markets and government.

Each magnet school has its own classrooms and library. The Arts School has a small theater and studios for dance, television, painting, sculpture, and graphic art. The City School has courtrooms, a bank, and a store. Shared spaces include special education rooms and a gymnasium/cafeteria.

The renovation included installation of a new elevator, upgrade of mechanical, electrical, and plumbing systems as well as significant alterations to all interior spaces.
